Munguva dzekare, vanhu vaifa vadiki nekuda kwechirwere, kusvibiswa uye kuzvarwa. Nhasi, muchikamu chikuru chepasi rose, vanhu vanofa vachiri vadiki, uye vanofa nechirwere chinotadza kupararira: chirwere chemoyo, chirwere cheshuga, chirwere chegomarara, chirwere chepfungwa, chirwere cheshuga uye chirwere chemapfupa. Kana munhu akafa, anopiwa mari yechiremba wake, chikafu, uye mishonga. Asi vane imwe chete yakakura kwazvo yekuwedzera, uye haisi kusvibiswa kweropa, kudya kana hunhu. Inguva. Kukura kwesainzi, inonzi geroscience, kunobvunza mibvunzo mishoma: sezvatisingazvipinde nechirwere chepakutanga chete, tingaitei kuti tirambe tichiramba tichikura? Iyi peji inotaura, zvakajeka uye zvakarurama sezvatinogona, kuti izvi zvinoratidzwa sei neongororo iyi, zvipi zvazvisina kuratidzwa, uye kuti zvinogona kuita sei kwatiri.

$38 trillioninofungidzirwa kukosha kweUS yekuderedza aging zvakakwana kuti vadzivise gore rimwe rehupenyu hunogona kutarisirwa (Scott et al., 2021)

Nei kukura kwevanhu kuri kuwedzera kukonzera chirwere cheshuga

Ona chero chirwere chinotambura nemakore uye chinoratidzawo kuti: chinowanzoitika muvadiki, asi ichikwira zvakanyanya nemakore. MuUnited States muna 2025, pamusoro 0.5 muzana yevanhu vakura makore 18 kusvika 44 aiva nguva dzose akawanikwa ane coronary moyo chirwere; pakati pevanhu vane makore 75 uye kupfuura yakanga 19 muzana. Any cancer: 2 percent against 33 percent. Arthritis: 6 muzana ne53 muzana (NCHS, NHIS 2025). New cancer diagnoses rinobva pamusoro 236 per 100,000 vanhu gore pamakore 40 kusvika 44 kuti pamusoro 2,400 pa 80 kusvika 84 (NCI SEER). Kunyanya vanhu vari pasi pemakore 65, huwandu hwevanhu vari kurwara nechirwere ichi hunowedzera kaviri pagore kusvika pakusvika mumwe muzana wevanhu vane makore 90 kana kupfuura.Manly et al., 2022).

MuUS data pamusoro, coronary chirwere chemoyo ndezve 38 nguva sezvinoitika pa 75 uye kupfuura sepa 18 kusvika 44. Izvi ndizvo zvakaita kuti nyanzvi dzehutano dzipinde munyaya yekuti vanhu vakura sei, vachiti “izvi ndezvekukonzera chirwere chikuru chinokonzeresa chirwere cheshuga” uye kuti kuongororwa kwevanhu vakakura kunotibatsira sei kuti tirambe tiri pahupenyu hwakanaka.Kennedy et al., 2014). Chii chinonzi geroscience? Iine zvikonzero zvekushandisa. Kurapa chirwere chepakutanga chinowedzera upenyu hwakawanda, asi vamwe vari kumirira: vanhu vakachengetwa kubva pamoyo vanotanga kurwara nekanzera, dementia kana stroke makore mashoma gare gare. Kuderedza kuora mwoyo kunozozvibata zvese zvakadzokera kumashure pamwechete.

Vachiremba vakaedza kuisa mari panyaya iyi. Muongororo wakaitwa mu2013 kuUS yakaratidza kuti kana vanhu vakarasikirwa nemakore akawanda, vanokwanisa kuramba vachirarama kwemakore 2.2, uyewo vari pahutano hwakanaka, izvo zvinoda mari inosvika $7.1 trillion pamusoro pemakore 50 (Goldman et al., 2013). Kudzidza kwe2021 kwakafungidzira kuti kunonoka kwekukura kwakakwana kuwedzera gore rimwe rehupenyu hwakareba zvichave zvakakwana $38 trillion to the US, and ten years $367 trillion (Scott, Ellison neSinclair, 2021). Izvi ndezvemamodeli akavakwa pazvinhu zvakajairika, asi zvinoratidza kuti nei magovera nevanoita mari vachipa pfungwa dzavo.

Chii chinogona kuitika: zviratidzo zvekukura kwevanhu

Kukura kwevanhu hakusi imwe nzira asi mimwe, inoitika pamwe chete uye ichibatsirana. Mu 2013 timu yakatungamirirwa naCarlos López-Otín yakavaunganidza muzvina pfungwa dzekukura, uye mu2023 yakakanganisa runyorwa rwemazana maviri (López-Otín et al., 2013; López-Otín et al., 2023). Mumashoko akajeka:

  • Genomic instability: dambudziko reDNA rinowedzera nekukurumidza kupfuura zvarinogadzirirwa.
  • Telomere attrition: zvinodzivirira zvipfeko pamadziro echromosomes zvinovhara pasi.
  • Epigenetic zvikonzero: zvekemikari marks kuti switch genes pamusoro uye off drift kunze yavo youthful pattern.
  • Kurasikirwa neproteostasis: mapuroteni anozvibata zvakaipa uye anotambanudza pamwe chete.
  • Disabled macroautophagy: chigadzirwa cheiyo cell’s recycling system chinononoka.
  • Deregulated nutrient sensing: kukwira masignals semuenzaniso mTOR uye insulini kumira wakaiswa pashure apo kudzoreredza zvaizoita zvakanaka.
  • Mitochondrial dysfunction: simba remagetsi re cell rinoita mashoma emagetsi uye zvigadzirwa zvinokuvadza.
  • Cellular senescence: zvakakuvadzwa muviri kubvisa kuparadzana asi vanobvuma kufa, uye kuburitsa inflammation mapoinzi.
  • Stem cell exhaustion: zviwanikwa zvinogadzirisa tishu zvinomira.
  • Alterated intercellular communication: masimba pakati pezvirwere uye mishonga inoitika zvakaipa.
  • Chronic inflammation: a low, constant inflammation, sometimes called “inflammageing”.
  • Dysbiosis: kugadzikana kwemicrobes muzvipfuwo zvinochinja.

Nekuti zvose zvinotaurwa pawebhusaiti ino zvinotarisana neimwe kana zvakawanda dzezviratidzo izvi. Zvinodiwa zvemufananidzo ndezvekuti: inofanira kuonekwa nemakore, ichiwedzera nguva yacho, inofanira kuwedzera nguva yekukura kwayo, uye ichiideredza nguva yake, inofanirwa kuwedzera nguva yekukura kwayo. Chimwe chezvikonzero nei pfungwa iyi ichishandiswa zvakanyanya ndechekuti, kune vamwe vanhu, kuongorora kwevanhu kunoda nguva yakareba kupfuura kuongorora kwenyama.

Tinoziva sei? An evidence scale

Chirevo “anti-ageing” chinotaura nezvezvose kubva kune zviito zvakaratidza kubudirira muvanhu vanopfuura mamiriyoni maviri kusvika kune zviito zvakaongororwa nemunhu mumwe chete. Kuti tichengete zvakasiyana, chero nzira pane iyi peji inotakura imwe yemhando mbiri:

  • Yakaratidza muvanhu: dzidzo huru dzevanhu uye kuongororwa kwaka randomized zvinoratidza zvishoma chirwere uye kufa.
  • Kuedza kwevanhu kunopa chivimbo: kuongororwa kwakaitika muvanhu zvinoratidza kuti zvinoita basa, asi hazvisizvo panyaya yekukura kwevanhu.
  • Strong in animals: yakapetwa, yakasimba mikana muzvinyama; vanhu chokwadi chidiki, zvakasiyana kana chete kutangira.
  • Early kana speculative: yakaderera, yakapikisana kana imwe-yekudzidza chokwadi, kana kuedza kwevanhu kusvika parizvino zvakanyanya pasina chikonzero chakajeka.

Kuti zvive pachena: hapana chinhu paiyi peji chakaratidzwa kuti chinoderedza kana kudzosera hupenyu hwevanhu sechinhu chega. Hapana chiremba, chikafu kana chiremba wegene anobvumidzwa kurapa hupenyu hwevanhu chero kupi pasi rose. Saka nei vakazvipira vatsvakurudzi vachifara? Nekuti makore makumi maviri apfuura hapana munhu aigona kuvimbisa kusimudzira hupenyu hwenyama inorarama neropa, uye zvino mishonga yakawanda inoita izvi, muzvidzidzo zvakaomarara mumalaboratories akasiyana-siyana; nekuti ma cell akawandisa anogona kuita kuti aite sezvinoita vana vechidikizve mumvura yekudya uye, muzvimwe zvirwere, muzvipfuwo; uye nekuti zvinotarisirwa kuti vanhu vatsva vaone biology yekukura kwevanhu, kwete chirwere chimwe chete. Kufamba kubva panyama kuenda kumunhu kunotora nguva yakareba, uye mikana yakawanda inotarisirwa haisi kuitika. Asi chinangwa chacho chinoratidzika pachena.

Kuziva zvinhu zvinovaka muviri: mTOR nerapamycin

Evident grade: kuvimbisa ongororo dzevanhu

Chii chinonzi? Kana muviri wako uchida kurarama, unofanira kuita zvinhu zviviri: Kukura kana kuti kubvisa. A protein complex called mTOR (The mechanistic chinangwa rapamycin) inoita kuti kufona: kana kudya uye kukura zviratidzo vari akawanda, mTOR inoti “kura”; kana vachiri vashoma, inodzokera kumashure uye cell switches kune maintenance, kusanganisira rekudzokorora yayo yakadzingwa zvinhu kuburikidza autophagy. Panguva yepakutanga, mTOR inoramba ichishanda kupfuura zvainoda kuti iite. Kudzokera pasi ndeimwe yenzira dzakaomarara dzekuwedzera hupenyu hweyeast, maworms, fly uye mouse.

Rapamycin ichirimwa chinonzi chinodzivirira mTOR. Yakawanikwa mumufananidzo wevhu kubva kuRapa Nui (Island yePasi), iyo yakapa zita rayo, uko inogadzirwa nebacteria, Streptomyces hygroscopicus (Vézina, Kudelski and Sehgal, 1975). Pazviyero zvakakwirira zvashandiswa kwemakore akawanda kuti zviite kuti muviri usabvumire kusvibiswa kwemararamiro.

Muzvinyama. Mu 2009 US National Institute on Aging’s Interventions Testing Program, iyo inoongorora zvinhu mumishonga yemuromo yakasiyana-siyana nemhando dzakasiyana dzemishonga palaboratories matatu panguva imwe chete, yazivisa kuti rapamycin yakawedzera upenyu hwemunhu kunyange kana ichipihwa pazuva re600, risati rasvika pakukura kwemuromo. Kutanga pazera iri, kutarisirwa kwehupenyu kwakakwira ne28 muzana muvakadzi uye 38 muzana muvarume (Harrison et al., 2009). Pakuwedzera kwedosi rakatangira mumakore epakati, hupenyu hwehupenyu hwakakwira ne23 muzana muvakadzi uye 26 muzana muvarume (Miller et al., 2014). Rapamycin ndiyo chete mishonga inoshandiswa mumishonga iyi inoshanda zvakasimba pavanhu vaviri, uye iriwo mishonga ine simba kwazvo rekusimudzira hupenyu hwemamamiriro ekunze.

Muvanhu. Mumwe munhu muenzaniso ndewechokwadi asi zvishoma. In a randomised trial in older volunteers, six weeks of everolimus, a close relative of rapamycin, improved the response to a flu vaccine by about 20 percent (Mannick et al., 2014), and a later trial of a related combination reduced infections over the following year (Mannick et al., 2018). But a larger phase 3 trial of a similar drug, in more than 1,000 older people, found no reduction in respiratory illness (Mannick et al., 2021). PEARL trial yakapa vanhu vane hutano vadiki madosi e rapamycin kwevhiki imwe chete kwemazuva 48. Hapana chaakachinja chiyero chayo chekutanga, visceral fat, uye zviratidzo zvepamberi zvakafanana neplacebo; zvimwe zvepamusoro zvinodiwa, senge masimba emakumbo evanhukadzi pakuwedzera kwedosi, zvakavandudzwa (Moel et al., 2025). Kuongorora kwe2024 kwe19 dzidzo hakuone chero zvakaipa zvinokonzerwa nehutano hwevanhu, asi zvimwe zvirwere uye zvishoma zveropa muvanhu vakange vaine hutachiona hwakafanana nehupenyu (Lee, Kuerec and Maier, 2024).

Risks. At transplant doses, rapamycin suppresses the immune system and carries warnings about serious infections and some cancers. Muromo ulcers, kukwira cholesterol uye triglycerides, slower kurapwa kweropa uye fluid build-up ndezvimwe zvemhedzisiro (US FDA sirolimus label). Mumishonga, kushandiswa kwenguva refu kunokonzerawo kuoma kweinsulini (Lamming et al., 2012). Vatsvakurudzi vari kuedza nhamba shoma uye dzakasvibiswa dzezvirwere, pamwe nezvinodhaka zvitsva zvinorambidza chete chikamu chemTOR chinokonzera hupenyu hwakareba.

Senolytics: kubvisa “zombie” macell

Evident grade: strong in animals

Chii chinonzi? Kana muviri wemunhu uchikuvadzwa zvakaipa, unogona kusangana nemamiriro anonzi senescence: unomira kuparadzana, izvo zvinodzivirira kubva kune cancer, asi haufarire. Senecious selula dzinova nemakore. Zvakaipa, ivo kuburitsa cocktail yeinflammatory masimba, senescence-inobatanidza secretory phenotype (SASP), iyo inokuvadza zvakachengeteka macells pamusoro pavo (Coppé et al., 2008). Senolytics zvinonzi majekiseni anoshandiswa kuuraya chirwere cheshuga.

Muzvinyama. Mu2011, vatsvakurudzi vakagadzira maminetsi emhando yepamusoro kuti hupenyu hwavo hwese hunogona kugadziriswa pavanoda. Kubvisa kwavo kwakaderedza kukuvadzwa kwepamuviri mufashoni, mishonga uye maziso (Baker et al., 2011). Muzvipfuyo zvakajairika, kubvisa izvi zvirwere kubva kumashure kwemakore akapetwa ne24 kusvika 27 muzana (Baker et al., 2016). Iyo yekutanga senolytic drug combination, dasatinib pamwe quercetin, yakawanikwa mu2015 (Zhu et al., 2015). Yakapihwa kune vanhu vadiki kwazvo, yakavandudza muviri webasa uye yakawedzera kurarama kwehupenyu ne36 muzana (Xu et al., 2018). Fisetin, a natural compound found in strawberries, extended lifespan when given to old mice (Yousefzadeh et al., 2018).

Muvanhu. The first human results are small and mixed. Muvanhu 14 vane hutachiona hwepafu, idiopathic pulmonary fibrosis, zvitatu zvemasvondo edasatinib plus quercetin zvakavandudza kufamba kwekufamba uye kumhanya, kunyangwe hazvo kwete kutenderera kweropa, mubvunzo pasina placebo group (Justice et al., 2019). Muvanhu vasere vane chirwere cheshuga cheshuga, mishonga yakaderedza senescent cells mufashoni uye muviri uye yakaderera inflammatory signals muropa (Hickson et al., 2019). Asi mubvunzo wakatorwa nevanhukadzi vane makore 60, mishonga iyi yakaratidza kuti haisi kuvandudzwa kwemapfupa; chete varume vane macells ane makore akawanda vakaona kuti vanowana mari (Farr et al., 2024). Mudzidzo yekuita muvanhu vashanu vane chirwere cheAlzheimer, dasatinib yakasvika mukutenderera kwepfungwa asi quercetin haisi (Gonzales et al., 2023). Mazhinji fisetin bvunzo paMayo Clinic iri kuenderera mberi (ClinicalTrials.gov NCT03675724).

Iyo yekutanga kambani yakavakwa pamusoro pesenolytics, Unity Biotechnology, yakati iongorore inouraya maziso, UBX1325 (foselutoclax), yechirwere chemaziso chediabetic. Mushure mekukurudzira kuedza kwekutanga, kuwedzera kwechikamu che2 chekuongorora ichienzanisa nechirongwa chekurapa chakasiya chinangwa chayo chakakosha (Unity Biotechnology, 2025), uye kambani yakaparadzwa mushure megore iro (SEC filing, 2025).

Risks. Dasatinib ichiri chiremba chekanzera nematambudziko ekunze, kusanganisira zvikonzero zvekushaya mvura muropa. Senescent selulawo vane mabasa anokosha, semuenzaniso pakurapa zvirwere, saka kubvisa kwavo hakusi pasina njodzi.

NAD +, NMN uye NR

Evident grade: yakatanga kana speculative

Chii chinonzi. NAD + ndeimwe yemamolecule ezvidiki izvo zvese zvikamu zvinoda kushandura kudya kuita simba uye kugadzirisa DNA. Zviyero zvayo zvinodzikira nemakore muzvirwere zvakawanda. Mamwe maprecursors ayo muviri anogona kushandura kuita NAD +, nicotinamide mononucleotide (NMN) uye nicotinamide riboside (NR), anotengeswa sezvipfuwo.

Muzvinyama. Mumishonga, gore reNMN mumvura yekunwa yakagadzirisa akawanda shanduko dzinokonzerwa nemakore, kusanganisira kukwira kwehuremu uye kudzikira kwekushandisa simba (Mills et al., 2016), uye NR yakavandudza mitochondrial uye stem cell function uye yakawedzera zvakanyanya upenyu hwevanhu vadiki (Zhang et al., 2016). Asi apo Interventions Testing Program yakaongorora NR neyakaomarara dhizaini, haisi kusimudzira huremu hwehupenyu mune chero chiito (Harrison et al., 2021).

Muvanhu. NR neNMN zvinowedzera zvakachengeteka NAD + muropa (Martens et al., 2018). Iyo yakanyanya kuzivikanwa yakajairika bvunzo yakapa NMN kune 25 vakadzi vane prediabetes kwemakumi maviri evhiki: kugadzikana kweinsulin yemuscle kwakavandudzwa ne25 muzana, asi chirwere cheropa, mafuta eropa uye kuumbwa kwemuviri hakuchinja (Yoshino et al., 2021). Mudiki bvunzo muchirwere cheParkinson, NR akawedzera NAD mupfungwa neyakajeka chiremba kuvandudzwa (Brakedal et al., 2022); kuwedzera bvunzo yakati wandei yakapera uye zvidzidzo zvayo zvinotarisirwa. Kuongorora kuti pool kuedza kusvika parizvino kuwana zvipfuwo zvakachengeteka munguva pfupi asi nevamwe hapana chiratidzo chakakosha kubatsira glucose muviri, muviri mafuta kana mishonga (Zhang et al., 2025; Prokopidis et al., 2025). Chii hachiratidzwe: kuti kusimudzira NAD + kunoderedza hupenyu hwevanhu kana kubvisa chero chirwere muvanhu.

Regulation. Mu2022, US Food and Drug Administration yakataura kuti NMN haigone kutengeswa sekudya kwekudya nekuda kwekuti yaive ichidzidza sechiremba; muna Zvita 2025 yakachinja iyo maonero (FDA, 2025). Kuve pakutengesa inoti hapana nezve kana chigadzirwa ichishanda.

Sirtuins uye resveratrol nyaya

Evident grade: yakatanga kana speculative

Chii chinonzi. Sirtuins ndeimwe yemhuri ye enzymes, makumi mana mumamiriro ezvinhu, ayo anoshandisa NAD+ kudzora DNA yekudzoreredza, metabolism uye gene activity. Mu 2003, ongororo yakazivisa kuti resveratrol, a compound yakawanikwa mu red grapes, akavhura sirtuin uye akawedzera upenyu hweyeast (Howitz et al., 2003). Mu 2006 resveratrol yakawedzera hutano uye kurarama kwemazino pa high-calorie kudya (Baur et al., 2006). Mu 2008, GSK yakatenga Sirtris, kambani inogadzira sirtuin activators, yemadhora anenge 720 miriyoni (GSK uye Sirtris, 2008).

Zvino yakanga yakafa. Nyaya iyi haisi kutevedzera zvakanaka. Resveratrol haana kusvikira hupenyu hwemaminetsi ezvipfuyo zvakajairika pakudya (Pearson et al., 2008), kusanganisira muInterventions Testing Program (Miller et al., 2011). Biochemists vakawana kuti zvakajeka kumisikidza kwayo kweSIRT1 sirtuin yaive yakatarisana neyakagadzirwa fluorescent tag yakashandiswa mubvunzo (Kaeberlein et al., 2005; Pacholec et al., 2010). Nekuti zvakajairika hupenyu hwehupenyu hwekuwedzera sirtuin muzvirwere uye mabhureki zvakanga zvadzikira zvakanyanya kana genetic backgrounds yakanyatso kudzorwa (Burnett et al., 2011).

What remains credible. Sirtuins still matter. Mishonga yakagadzirwa kuti iite zvakawanda zvemumwe sirtuin, SIRT6, yaive nehupenyu hwakareba: mukadzi chete mukutanga dzidzo (Kanfi et al., 2012), uye mune imwe yekupedzisira dzidzo 27 muzana yakareba median hupenyu muvakadzi nevarume uye 15 muzana muvarume, nekuwedzera kwehutachiona (Roichman et al., 2021). Chii chinonzi genetics, kwete pill. No sirtuin-activating zvipfuwo zvakaratidzwa kuti kuwedzera kwemakore muvanhu.

Telomeres uye telomerase

Evident grade: yakatanga kana speculative

Chii chinonzi. Telomeres ndezvimwe zvemasimba eDNA ayo anowedzera kana kuchinja zvikamu zvechromosome yedu, sezvinoita mabhureki ekushongedza. Vachakurumidza kuderera pavanoparadzana; kana vachiita kuti vaite sekuti vari vadiki, muviri wemunhu unomira kuparadzana kana kuti anofa. An enzyme called Telomeres anogona kuvakwazve. Elizabeth Blackburn, Carol Greider uye Jack Szostak vakabatanidzwa mu2009 Nobel Prize muPhysiology kana Medicine yekutsvaga kuti sei izvi zvinoshanda (Nobel Prize, 2009).

Muzvinyama. Mu2012, nyanzvi dzemuSpanish National Cancer Research Center dzakapa midzi yakakura mushonga wegene uyo wakachinja telomerase kuti iite basa rayo. Median hupenyu hwaive ne24 muzana mumidzi yakagadziriswa pagore rimwe chete uye 13 muzana mumidzi yakagadziriswa pamakore maviri, pasina kukwira kwechirwere (Bernardes de Jesus et al., 2012). Izvi zvinoramba zvichireva kuti hapana chikonzero chekuzviisa pasi.

The cancer problem. Cancer cells need to divide without limit, and most of them do it by switching telomerase on: in a landmark study, 90 of 101 tumour samples had telomerase activity, and none of 50 normal tissues did (Kim et al., 1994). Vanhu avo magene anovapa telomeres akareba vane kuwedzera kwechirwere chemoyo asiwo kukonzera chirwere cheshuga, gliomas, adenocarcinoma yepamuviri uye melanoma (Haycock et al., 2017). Telomeres pfupi hazvisi chete “zvakaipa” uye zvose “zvakanaka”.

Muvanhu. Zvimwe zvirwere zvakadai sedyskeratosis congenita zvinokonzerwa nematambudziko e telomerase uye zvinogona kukonzera chirwere cheshuga yeropa, kurwadziwa kwepamuviri uye kufa kwakaoma.Armanios uye Blackburn, 2012). Mubvunzo muzviremba, hormone danazol akawedzera telomeres mu11 ye12 vanhu vaigona kuongororwa (Townsley et al., 2016). Chirwere ichi chine chirwere chinoitika kakawanda, asi hachikonzere kuora mwoyo. Kuzvipira ye chero mashoko kuti chigadzirwa kana kliniki “inowedzera telomeres yako” kuti iwe uite uchikura: mu2015 mukuru wekambani imwe akati aive akagamuchira telomerase gene therapy kunze kwenyika, asi mapepa haasi kunyatsoongororwa mune peer-reviewed study (MIT Technology Review, 2015).

Kugadzirisa kwechinguvana neYamanaka factors

Evident grade: strong in animals, first human trial underway

Chii chinonzi? Mu 2006 Shinya Yamanaka akaratidza kuti kuchinja kweanenge maviri chete emhando dzemagene, ayo anonzi Yamanaka factors (OCT4, SOX2, KLF4 uye c-MYC, kana OSKM), anoshandura muviri wemunhu wepakutanga kuita muviri we embryo-yakaita stem cell iyo inogona kuve chero mhando yechigadzirwa che cell (Takahashi and Yamanaka, 2006). Akawana mu2012 Nobel Prize for Physics.Nobel Prize, 2012). Panzira, makore e cell anobvisa: makemikari emazita paDNA ayo anodzokera kurudziro yevadiki. Chii chinonzi partial reprogramming ndechokuti tiite zvinhu izvi chete kwenguva pfupi, nguva yakareba zvakakwana kuti tidzosere zviratidzo zvemakore asi kwete nguva yakareba zvakakwana kuti muviri urege kuziva zvazvinoreva.

Muzvinyama. Mu2016, maminetsi ayo achiri kukura zvakapihwa OSKM mumigwagwa, mazuva maviri nemakumi mana ezuva. Masimba avo akaratidza zviratidzo zvakaderera zvekukura uye vakararama kwenguva yakareba (Ocampo et al., 2016). Mu 2020, matatu ezvikonzero (OSK, kubvisa c-MYC inobatanidza katsi) yakapihwa kumaziso emazino ane glaucoma-senge kurasika uye emazita emakore, uye akadzosa kuona kwavo nekuisazve mazita paDNA yechiropa chemoyo (Lu et al., 2020). Kuenderera mberi kwenguva refu kwekudzokorora kurongwa muzvipfuyo zvinokura zvakajairika kwakachinja akawanda emolecular markers kuenda kune yakaderera mamiriro (Browder et al., 2022), uye mune imwe ndogo studie, een OSK genetherapie die wordt gegeven aan zeer oude mannelijke muizen dubbeld hun resterende mediane levensverwachting (Macip et al., 2024).

The companies and the first trial. Partial reprogramming has attracted some of the largest investments in biotechnology. Altos Labs launched in January 2022 with $3 billion (Altos Labs, 2022). Retro Biosciences, backed with $180 million by Sam Altman (MIT Technology Review, 2023), works on reprogramming and says its first drug, a pill aimed at cellular recycling, entered a phase 1 trial in 2025 (Retro Biosciences, 2026). NewLimit raised $435 million in 2026 and says it plans a first human trial of a liver therapy (NewLimit, 2026). The first reprogramming therapy to reach people is ER-100 from Life Biosciences, an OSK gene therapy injected into the eye for two diseases of the optic nerve, glaucoma and non-arteritic anterior ischaemic optic neuropathy (NAION). The US Food and Drug Administration cleared the trial in January 2026 (Life Biosciences, 2026), and the first patient was treated in June 2026 in a phase 1 safety study of 18 people (ClinicalTrials.gov NCT07290244; Life Biosciences, 2026). Results will take years. Company announcements are not peer-reviewed evidence, and we will update this page as results are published.

Kana nzvimbo dzese dzichichinja. Zvimwe zvezvinhu zvakaomarara zvave kuitika kana vanhu vachichinja pamwe chete. In North Karelia, Finland, a region-wide programme from 1972 cut smoking, cholesterol and blood pressure, and deaths from coronary heart disease among people aged 35 to 64 fell by 82 percent in men and 84 percent in women by 2012 (Jousilahti et al., 2016; Puska et al., 2016).

Mazuva akareba sei ekurarama nehutano angachinja huwandu hwevanhu

Iyo nyika iri kusangana nemamiriro ezvinhu anochinja munyaya dzezvematongerwo enyika ayo haasi kuitika kare. Sezvo United Nations inoti, huwandu hwevakadzi vanozvarwa pasi rose pari zvino huri pa2.25 emadzimai ese, zvichikwira kubva pa3.31 muna 1990; kupfuura hafu yenyika dzese nenzvimbo dzine huwandu hwevana hwaisvika pasi pe2.1, uye anenge mumwe muzana ane hukuru hwevana hwakaenzana kana kuti 1.4.

Munyika nenzvimbo 63, dzinobata 28% yevanhu, huwandu hwevanhu hwasvika pakumuka. By the late 2070s, people aged 65 and over are projected to outnumber children under 18 (UN World Population Prospects 2024). Zvikonzero zvekuti kubereka kunodzikira, uye nei Local Solar System Foundation ichitsigira dzidzo nesarudzo dzakanaka dzese dzemhuri, zvinoratidzwa pawebhusaiti yedu ye vanhu, kushandiswa kwezvinhu uye zvinhu.

An older population is usually described as a burden: fewer workers supporting more retirees. The standard measure, the old-age dependency ratio, counts people aged 65 and over for every 100 people aged 20 to 64. Maererano nehuwandu hweUN, muna 2024 vanhu vepasi rose vaisvika pa18 uye zvinotarisirwa kuti vachasvika pa29 mu2050 uye pa44 mu2100; muJapan vanhu vacho vari pa55 (UN World Population Prospects 2024).

Kukura kwevanhu hakusi nhamba yakamira

Chiyero ichi chinoti munhu ane makore 65 ekuberekwa mu2100 achave nemakore 65 ekuberekwa sezvaaiita muna 1950. Demographers Warren Sanderson uye Sergei Scherbov vakapikisa kuti izvi zvinovhiringidza. Vachikurudzira kuongorora makore vanhu vakanga vasingagoni kurarama, kwete makore avo vakanga vagara, uye vakaratidza kuti vanhu vanogona “kukura vachiri vadiki” nekudaro kunyange zvazvo makore avo anenge ari pasi pemakore makumi maviri nemasere (Sanderson naScherbov, 2005; Sanderson naScherbov, 2010). Mumwe mufananidzo unoisa chiyero chemakore ekare apo kutarisirwa kwehupenyu hwakaremara kunosvika pasi pe15 makore: kune vechiFrench, iyo yaive 58 muna 1900 uye yakasvika 75 muna 2012 (Sanderson and Scherbov, 2015).

Chii chinonzi healthy. Pasirese, kutarisirwa kwehupenyu kwakakwira kubva pamakore 66.8 kusvika pamakore 73.1 pakati pe2000 ne2019, uye hukama pakati pekutarisirwa kwehupenyu uye kutarisirwa kwehupenyu hwakanaka hwakawedzera kubva pamakore 8.5 kusvika pamakore 9.6 (World Health Organization; Garmany neTerzic, 2024).

Pashure, hutano hwevana

Vabereki vari kubereka vana vadiki zvakanyanya. Munyika dzeOECD, huwandu hwemakore emadzimai pavanenge vachizvarwa vasati varoora hwakwira kubva pa26.4 mu2000 kusvika pa29.6 mu2024 (OECD Family Database). The ovaries show marked ageing earlier than most other tissues in the body (Garrison, 2026), and declining fertility in the late thirties and forties limits how many children people who start later can have. Kuongorora kwepabonde kunoitwa negeroscience: semuenzaniso, VIBRANT trial yakaitwa kuColumbia University yakati inoratidza kuti sei kurapwa nerapamycin pazera rakareba rinogona kubatsirawo pakuderedza kushaya kwevakadzi vane makore 35 kusvika 45 (ClinicalTrials.gov NCT05836025); izvo zvinonzi zvakaitika hazvo hazvina kuburitswa.

Nei vakawanda demographers kutarisira kushushikana kuti kupera

Ichokwadi kuti zvinokosha kuva nechokwadi nezvekutaura kwakasiyana. Vaongorori veGlobal Burden of Disease vanofungidzira kuti 155 kubva ku204 nyika nenzvimbo dzichave nehuwandu hwevana hwaisvika pasi pekuchinja kwevanhu kusvika muna 2050 uye 198 kusvika muna 2100; kubva kumatunhu e47 uko huwandu hwevana hwawedzera, zvitatu chete zviri pamusoro pekuchinja kwevanhu (GBD 2021 Kubereka uye Kufungidzira Vatsigiri, 2024). The UN judges that countries with very low fertility whose populations have already peaked are highly unlikely to return to replacement within 30 years (UN World Population Prospects 2024). Vamwe demographers kuratidzwa anogona low-fertility trap, uko kushaya kwemakore akawanda, kushoma kwemhuri uye kushushikana kwezvehupfumi kunowedzerana (Lutz, Skirbekk uye Testa, 2006), uye vaongorori vezvehupfumi Dean Spears naMichael Geruso vanotaura kuti pasina kuchinja kwechirongwa, huwandu hwevanhu pasi rose huchadzikira kwenguva yakareba mushure mekusvika pakumutswa (Spears uye Geruso, 2025). Kurarama kwenguva yakareba kusingagadzirise dambudziko iri: zvinoderedza kuwedzera kwevanhu, asi munguva pfupi vanhu vane vana vashoma vanowedzera.

Isu hypothesis: kuderera ndechinguvana dambudziko

Local Solar System Foundation’s view is that population decline is a temporary problem, a transition to adapt to rather than a permanent crisis. Ticharatidza izvi sechirevo, nemamiriro edu uye nechokwadi chekuti zvinoratidza kuti zviri pachena kana zvisina.

Kufunga.

  1. Kurarama kwenguva yakareba nehutano kunoreva kuti kuzvarwa kuri pasi pehuwandu hwevanhu hwakakodzera kuti huve hwakachengeteka. Muhurombo hunoramba huripo, huwandu hwevanhu huchaenzana nehuwandu hwevanhu vanozvarwa pagore zvichienzaniswa nehuwandu hwevanhu vari kutarisirwa kurarama pavanenge vazvarwa, izvo zvinonzi demos (Preston, Heuveline and Guillot, 2001). Kana kutarisirwa kwehupenyu kuchikwira kubva pamakore 73 kusvika pamakore 90, vanhu vakafanana vanogona kuchengetwa nezana regumi nemasere emavambo mashoma pagore.
  2. Kuita tsvakurudzo yezvehutano, kwete makore, ndiko kuri kutungamira pakuziva kuti munhu anofanira kubatsirwa. Kana geroscience ichikwanisa kuderedza hutachiona hwemakore nemakore mashoma chete, huwandu hwevanhu vari kurarama vachida rubatsiro rwavo hucharamba huri pedyo nehuwandu hwevanhu vari munyika pari zvino, kunyange hazvo vanhu vachiwedzera kukura, sezvakaratidzwa mumifananidzo iri pamusoro apa.
  3. Kuita kuti vanhu vawane vana vakawanda kupfuura zvavanoda kunogona kubatsira. Kana kushaya mwana kuchikwanisa kunonoka, kurarama nemwana munguva pfupi hakusi kuzoreva kuti munhu anenge aine vana vashoma.
  4.
