Mmetụta ọkwa cellular nke GHK-Cu na nrụzi akpụkpọ ahụ
Na-akwalite ọrụ Fibroblast
Fibroblasts bụ ụdị mkpụrụ ndụ bụ isi na-ahụ maka imepụta matrix extracellular (ECM) na akpụkpọ ahụ, nke gụnyere ihe ndị dị ka collagen, elastin, na glycosaminoglycans, bụ ndị niile dị oke mkpa maka idowe nhazi akpụkpọ ahụ na ngbanwe. GHK-Cu nwere ike kpalie fibroblast proliferation, na-enyere ndị ọzọ fibroblasts isonye na nhazi nhazi akpụkpọ ahụ. GHK-Cu nwere ike imezi okwu nke mkpụrụ ndụ ihe nketa metụtara njikọ njikọ collagen, dị ka ụdị ntinye koodu nke I na ụdị III collagen, si otú ahụ na-abawanye njikọ na nzuzo nke collagen. Collagen bụ protein kachasị ukwuu na akpụkpọ ahụ, ọkwa ya na-abawanye na-enye aka mee ka akpụkpọ ahụ dịkwuo ike na nkwụchi, na-akwalite nrụzi na mwughachi nke anụ ahụ mebiri emebi. GHK-Cu na-akpalikwa njikọ nke fibroblast nke elastin, nke na-eme ka akpụkpọ ahụ dịkwuo mma, na-enyere ya aka ịlaghachi n'ọnọdụ mbụ ya mgbe ọ gbatịchara. Nke a dị oke mkpa maka mweghachi nke ọrụ physiological nkịtị na ọdịdị akpụkpọ ahụ.
Na-achịkwa omume keratinocyte
Keratinocytes bụ akụkụ cellular bụ isi nke epidermis ma na-arụ ọrụ dị oke mkpa na ọrụ mgbochi akpụkpọ ahụ na usoro nrụzi. GHK-Cu na-akwalite mmụba nke keratinocyte, na-eme ka mmụba nke epidermal dịkwuo elu. Na-esochi mmerụ ahụ akpụkpọ ahụ, keratinocytes ga-amụba ngwa ngwa ma kwaga na ebe ọnya ahụ iji mepụta akwa epidermal ọhụrụ. GHK-Cu na-akwalite ịkwaga keratinocyte site n'ịkwalite ụzọ mgbaàmà intracellular, dị ka ụzọ nrịbama protein kinase (MAPK) nke mitogen-activated. Nke a na-enyere keratinocytes aka ikpuchi elu ọnya ngwa ngwa, belata ihe ize ndụ nke ibute ọrịa, ma nye ebe kwụsiri ike maka nrụzi akpụkpọ ahụ na-esote. Ọzọkwa, GHK-Cu na-achịkwa ọdịiche nke keratinocytes, na-enyere ha aka ịmepụta stratum corneum na-emekarị ma weghachite ọrụ mgbochi akpụkpọ ahụ.

GHK-Cu nwere ihe mgbochi mkpali, na-achịkwa okwu nke cytokines mkpali. Nnyocha na-egosi na GHK-Cu nwere ike igbochi mmepụta nke cytokines pro-inflammatory dị ka tumor necrosis factor-α (TNF-α) na interleukin-6 (IL-6), ebe ọ na-akwalite ntọhapụ nke cytokines mgbochi mkpali dị ka mgbanwe uto-β (TGF-β) na inducible nitric oxideOS synthase (iN). Site na usoro nhazi a, GHK-Cu nwere ike ibelata nzaghachi mkpali ma mepụta microenvironment dị mma maka ọgwụgwọ ọnya. N'ime ụdị mmerụ ahụ nke anụ ahụ zuru oke, ọgwụgwọ na GHK-Cu soluble microneedle patches mere ka mbelata dị ukwuu na okwu TNF-α na IL-6 n'ime anụ ahụ, ebe okwu TGF-β na iNOS mụbara, na-egosi na GHK-Cu na-egbochi nzaghachi mkpali ma na-akwalite ọgwụgwọ ọnya.
Mmetụta antioxidant
Nchegbu oxidative na-arụ ọrụ dị mkpa na mmerụ ahụ akpụkpọ ahụ na usoro ịka nká. Ụdị oxygen na-emebiga ihe ókè (ROS) nwere ike imebi biomolecules intracellular dị ka DNA, protein, na lipids, si otú ahụ na-emebi ọrụ cellular. GHK-Cu nwere ikike antioxidant, nke ọ na-enweta site n'ọtụtụ ụzọ iji wepụ ROS. GHK-Cu nwere ike imezi okwu nke enzymes antioxidant intracellular, nke na-eme ka ire ere nke ROS belata, si otú ahụ belata mmebi ha na sel. Na mgbakwunye, GHK-C nwere ike meghachi omume na ROS iji kwụsị ọrụ ha. Nnyocha ọmụmụ vitro egosila na GHK-Cu na-egbochi mmepụta ROS nke ọma na keratinocytes nke ultraviolet B (UVB) na-akpata, na-echebe mkpụrụ ndụ site na mmebi oxidative. Nke a dị oke mkpa maka nrụzi akpụkpọ anụ na mgbochi nke fotoaging.
