Na Cocer Peptides 
hashize iminsi 25.
Ibisaza hamwe nuruhu bituruka ku ngaruka ziterwa nibintu byinshi, birimo uburyo bwibanze nko gutakaza kolagen, kwangirika kwa okiside, kwangiza melanin, kugabanuka kwa telomere, no kugabanuka kwingufu za selile. Ibintu bya peptide, nka molekile ya bioaktike, byerekana ibyiza byihariye mukugabanya iminkanyari, kugenzura melanine, kurinda telomere, antioxyde, no kwera uruhu bitewe nintego zabo zidasanzwe hamwe na biocompatibilité. Mu kwigana peptide karemano cyangwa guhindura imikorere ya molekile, ibyo bice bigira uruhare runini muburyo bwo gusaza kwuruhu, gusana ibyangiritse kurwego rwa selile no kuvugurura imiterere yuruhu rwurubyiruko, bityo bigatanga ibisubizo bishya muburyo bwo kurwanya gusaza no kwisiga mubuvuzi.
Igicapo 1 Abashoferi basaza n'indwara ziterwa n'imyaka. Inkomoko: Uburyo bwa molekuline bwo gusaza no kurwanya gusaza (2024).
Ibice byingenzi byo gusaba
1. Kugabanya Iminkanyari: Kuvugurura imiterere ya Dermal na Elastique
Gukora uruhu rwuruhu bifitanye isano rya hafi no gutakaza dermal collagen, fibre fibre elastique, hamwe na fibroblast idakora neza. Ibicuruzwa bya peptide biteza imbere iminkanyari mugukora inzira ya kolagen synthesis inzira no guhagarika matrix itesha agaciro ibikorwa bya enzyme.
Gutezimbere synthesis ya kolagen
Oligopeptide yihariye yigana ibintu bikura-β (TGF-β) byerekana ibimenyetso, bitera fibroblast guhuza ubwoko bwa I na III kolagen na aside hyaluronike. Ibi byongera umubyimba wa dermal kandi bitezimbere iminkanyari ihagaze (urugero, imirongo yuruhanga, imitsi ya nasolabial).
Kugenga kwanduza imitsi
Peptide zimwe na zimwe (urugero, Snap-8) zibuza ishingwa rya poroteyine SNARE ya presinaptic, kugabanya irekurwa rya acetyloline no kugabanya amplitude yo kugabanuka kwimitsi yo mumaso. Ibi bigabanya imyunyu ngugu (urugero, imirongo ya glabellar, ibirenge byikona), hamwe ningaruka zigereranywa nuburozi bwa botuline ariko bihinduka cyane numutekano.
Gusana matrix idasanzwe
Peptide nka GHK-Cu iteza synthesis ya glycosaminoglycan, kongera amazi ya dermal, no kwihutisha gusana fibre ya kolagen yangiritse, kunoza uruhu rworoshye kandi neza.
2. Amabwiriza ya Melanin: Kuringaniza umusaruro wa pigment na metabolism
Kwibika kwa melanin bidasanzwe biganisha kuri pigmentation (urugero, melasma, izuba) ni ingorabahizi mu kwisiga. Ibintu bya peptide bigera kumubiri wuruhu binyuze muburyo bubiri bwo kugenzura imikorere ya melanocyte.
Kubuza synthesis ya melanin
Oligopeptide yihariye ihagarika ibikorwa bya tyrosinase n'imvugo ya mRNA, bigabanya ihinduka rya dopaquinone kuri melanin; glutathione (GSH) ikuraho radicals yubusa binyuze muri antioxyde, ikabuza okiside yo mu nda ya melanocytes mugihe itera melanin granule kwangirika no gusohoka.
Gufotora no kugenzura ibicuruzwa
Peptide nka Melanotan-1 / -2 ikora nk'imisemburo ya melanocyte itera imisemburo igereranya kugirango ikore reseptor ya MC1R, iteza imbere synthesis ya melanin no kuyikwirakwiza. Ibi byongera uruhu rwo kwirinda imishwarara ya ultraviolet (UV), bigabanya ibyago byo gufotora, kandi bikagera no kumubiri kugirango wirinde kwangirika kwa ADN bitagaragara.
3. Kurinda Telomere: Gutinda gusaza kwa Cellular
Kugabanuka kwa telomere ni ikimenyetso cyibinyabuzima cyo gusaza kwa selile, kandi peptide ya telomere yongerera igihe cyimikorere mugutunganya ibikorwa bya telomerase.
Kugenga ibikorwa bya telomerase
Peptide nka Epitalon yibasira uturere twa telomere ya kirimbuzi, ikora imvugo ya telomerase catalitike subunit (TERT) kugirango itinda rya telomere itinda kandi itinde gusaza kwa fibroblast na keratinocytes, bityo bikomeze ubushobozi bwo kuvugurura uruhu. Iyi peptide yongerera ingirabuzimafatizo no kunoza imikorere yinzitizi yuruhu no gufata amazi.
Kugena imvugo ya gene
Muguhindura ingirabuzimafatizo zijyanye no gusaza nka p53 na p16, peptide ya telomere ibuza gufata ingirabuzimafatizo kandi bikagabanya irekurwa ryimpamvu ziterwa na senescence zifitanye isano na senescence zifitanye isano n’ibanga (SASP), bikarwanya kasake yuruhu rusaza kuva inkomoko yabyo.
Igishushanyo 2 Imiterere ya Telomere na telomerase, nubusabane bwabo na selile senescence. Inkomoko: Uburyo bwa molekuline bwo gusaza no kurwanya gusaza (2024).
4. Antioxyde: Gukuramo Radicals Yubusa no Kurinda Imiterere ya selile
Guhangayikishwa na Oxidative ni intandaro yambere yo gusaza kwuruhu, kandi ibintu bya peptide bigira ingaruka zo gukingira binyuze muri antioxyde-intego nyinshi.
Ubuntu bukabije
Precursor peptide nka NAD yongerera imbaraga imbaraga za selile metabolisme, ikongera ibikorwa byimisemburo ya antioxydeant nka SOD na CAT, ikanagabanya ibyangiritse kuri anion ya superoxide na hydrogen peroxide; glutathione itesha agaciro radicals yubuntu, irinda selile membrane lipide na ADN kwangirika kwa okiside.
Kurinda Mitochondrial
Peptide nka SS-31 yashyizwe muri mitochondrial y'imbere, ibuza kurekura cytochrome C hamwe no gukora inzira ya apoptose, gukomeza ubushobozi bwa mito-iyambere, no gutanga ingufu zihamye. Ibi bigabanya imbaraga za okiside iterwa na keratinocyte apoptose hamwe no kwangirika kwa dermal.
5.Kwera uruhu: Multi-path Synergy kubwuruhu rwa nimugoroba
Kwera ntibisaba gusa kubuza melanin gusa ahubwo bisaba no kugenzura byimazeyo ubwikorezi bwa pigment, metabolism, hamwe nimbogamizi yuruhu.
Kubuza gutwara melanin
Ibicuruzwa bimwe na bimwe bya peptide bibuza ihererekanyabubasha rya melanin granules kuva melanocytes kuri keratinocytes, bikagabanya kwanduza epidermal; bongera kandi stratum corneum metabolism, byihutisha exfolisiyasi ya melanin irimo keratinocytes.
Kwivanga muri hyperpigmentation nyuma yo gutwikwa
Peptide nka KPV ibuza inzira ya NF-κB yumuriro, kugabanya UV- cyangwa gutwika biterwa na melanine ikabije. Ibi birakwiriye cyane cyane gusana pigmentation kuruhu rworoshye ndetse no gukomeretsa nyuma ya acne.
Umwanzuro
Gukoresha ibintu bya peptide mukurwanya gusaza no kwisiga byerekana gusimbuka siyanse kuva 'guhindura imiterere ' kugeza 'kwifashisha imashini.
INGINGO ZOSE N'AMAKURU Y’IBICURUZWA BITANZWE KURI URU RUBUGA BISANZWE KUBONA AMAKURU N'INTEGO Z'UBUREZI.
Ibicuruzwa byatanzwe kururu rubuga bigenewe gusa mubushakashatsi bwa vitro. Mu bushakashatsi bwa vitro (Ikilatini: * mu kirahure *, bisobanura mu bikoresho by'ibirahure) bikorwa hanze y'umubiri w'umuntu. Ibicuruzwa ntabwo ari imiti, ntabwo byemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA), kandi ntigomba gukoreshwa mu gukumira, kuvura, cyangwa gukiza indwara iyo ari yo yose y’ubuvuzi, indwara, cyangwa indwara. Birabujijwe rwose n'amategeko kwinjiza ibyo bicuruzwa mumubiri wabantu cyangwa inyamaswa muburyo ubwo aribwo bwose.
