Core Application Areas
1. Cov leeg nqaij loj: Txhawb nqa Myocyte Synthesis thiab inhibiting Catabolism
Cov tshuaj Peptide txhim kho cov leeg nqaij thiab ua haujlwm los ntawm kev tswj cov kab mob anabolic thiab catabolic.
Satellite cell activation thiab proliferation
Kev loj hlob hormone-tso peptides (xws li, CJC-1295) qhib kev loj hlob hormone secretagogue receptors, stimulating pituitary loj hlob hormone tso tawm thiab txhawb cov insulin zoo li kev loj hlob factor-1 (IGF-1) synthesis. Qhov no activates downstream txoj kev mus induce satellite cell hloov los ntawm ib tug quiescent xeev mus rau ib tug proliferative lub xeev, accelerating myofibrillar protein synthesis. Cov peptides no tseem inhibit ubiquitin-proteasome system kev ua haujlwm, txo cov leeg nqaij protein degradation, ua rau lawv tshwj xeeb tshaj yog haum rau kev laus, tsis siv cov leeg nqaij atrophy, thiab tom qab qoj ib ce kho mob.
Adipocyte metabolism thiab tiv thaiv cov leeg
Qee cov peptides (piv txwv li, AOD 9604) txo qis cov kab mob sib kis ntawm adipocytes thiab myocytes los ntawm kev ua kom cov nqaij ntshiv xim av thermogenesis thiab dawb adipose browning, txhim kho cov leeg nqaij microenvironment. Lawv tiv thaiv cov nyhuv ntawm myocyte mitochondrial muaj nuj nqi txo kev tawm dag zog vim oxidative puas tsuaj thiab txhawb kev qaug zog rov qab.
2. Kev Kho Hniav: Multistage Regulation of the Repair Process
Los ntawm inflammatory teb rau cov ntaub so ntswg remodeling, peptide tshuaj tswj tag nrho lub voj voog ntawm qhov txhab kho.
Inflammatory theem kev cai
Peptides xws li TB 500 inhibit kev ua haujlwm ntau dhau ntawm neutrophil thiab tso tawm dawb radical, txo qis kev puas tsuaj. Lawv kuj txhawb cov macrophage polarization mus rau cov tshuaj tiv thaiv kab mob M2 phenotype, ua rau kom tshem tawm cov ntaub so ntswg necrotic thiab tsim kom muaj qhov tsim nyog microenvironment kho.
Antimicrobial peptides (xws li, LL37) ncaj qha tua cov kab mob thiab tswj lub cev tiv thaiv kab mob chemotaxis, txo qhov mob ntawm qhov txhab. Lawv ua kom cov epidermal loj hlob yam receptors txhim kho keratinocyte migration peev.
Proliferation thiab remodeling theem nce qib
Kev tiv thaiv kab mob plab peptides (piv txwv li, BPC-157) ua kom vascular endothelial kev loj hlob zoo (VEGF) thiab fibroblast kev loj hlob (FGF) signaling, txhawb endothelial cell proliferation thiab neovascularization kom ceev lub qhov txhab ntshav reconstruction. Lawv kuj txhawb kev qhia ntawm hom I collagen thiab fibronectin, txhim kho granulation cov ntaub so ntswg lub zog.
Peptides xws li GHK-Cu, raws li cov neeg nqa khoom tooj liab ion, txhawb kev ua haujlwm ntawm lysyl oxidase, ua kom cov collagen fiber ntau sib txuas thiab kev loj hlob los txhim kho lub zog tensile ntawm caws pliav. Lawv inhibition ntawm matrix metalloproteinases txo qis ECM degradation ntau dhau, tiv thaiv caws pliav hyperplasia.
Daim duab 2 Bioactive peptides thiab cov proteins tswj ROS tsev neeg thaum lub sij hawm physiological thiab pathological txheej txheem. Tau qhov twg los: Bioactive peptides thiab cov proteins rau kev kho cov ntaub so ntswg: microenvironment modulation, rational delivery, and Clinical potential (2024).
3. Kev Kho Kho Kho: Kho pob txha mos thiab Synovial Inflamation Regulation
Lub hom phiaj ntawm pob txha pob txha hnav thiab synovitis, peptide tshuaj tiv thaiv chondrocytes thiab inhibit fibrosis.
Kho pob txha mos matrix
Chondroitin-related peptides (xws li, Chonluten) txhawb chondrocyte synthesis ntawm proteoglycans thiab hom II collagen, inhibiting pob txha matrix degradation thiab qeeb pob txha mos degeneration hauv osteoarthritis. Lawv upregulation ntawm cov noob caj noob ces tswj chondrocyte phenotype, txo hypertrophy thiab calcification.
Pob txha-tiv thaiv peptides (xws li, Cartalax) inhibit kev loj hlob ntawm fibroblast-zoo li synoviocytes (FLS) thiab pro-inflammatory factor secretion, alleviating synovial o vim pob txha mos erosion, haum rau adjuvant kho nyob rau hauv rheumatoid thiab traumatic mob caj dab.
Cell tiv thaiv thiab apoptosis inhibition
SS-31, mitochondria-targeted peptide, embeds nyob rau hauv chondrocyte mitochondrial daim nyias nyias, tswj daim nyias nyias muaj peev xwm stability thiab txo oxidative kev nyuaj siab-induced apoptosis los tiv thaiv cov ciaj sia taus ntawm sib sib zog nqus articular pob txha hlwb hlwb.
4. Kev Ua Si Kev Kho Mob Kev Kho Mob: Kev kho kom nrawm dua thiab ua haujlwm zoo dua qub
Rau cov leeg nqaij, cov leeg raug mob, thiab cov kua muag ligament, cov tshuaj peptide txhim kho kev ua haujlwm rov qab los ntawm kev tswj xyuas cov haujlwm ntawm tes thiab kho ECM.
Tendon / ligament kho txhim kho
Qee cov peptides (piv txwv li, TB 500 fragment) txhawb cov leeg qia cell sib txawv rau hauv tenocytes, txhawb kev qhia ntawm tenascin-C thiab tendonectin, txhim kho cov txheej txheem ntawm collagen fiber ntau, txo qis kev tsim cov nqaij mos, thiab txhim kho cov khoom siv ntawm cov chaw raug mob.
Peptides xws li CJC-1295, los ntawm kev loj hlob hormone tso tawm, txhawb satellite cell migration rau cov leeg raug mob, ua kom cov collagen fiber ntau synthesis thiab shortening lub voj voog rov qab ntawm kev raug mob kis las-tshwj xeeb rau cov neeg ncaws pob 'kev kho mob sai.
Xaus
Kev siv cov tshuaj peptide hauv kev kho cov leeg nqaij thiab cov nqaij ntshiv yog ib qho kev kho kho mob ntawm 'passive kho' mus ' nquag rov tsim dua tshiab.' Los ntawm kev tsom mus rau txoj hauv kev tseem ceeb xws li satellite cell activation, ECM remodeling, angiogenesis, thiab inflammatory regulation, cov tshuaj no sib npaug anabolic thiab catabolic metabolism hauv cov nqaij ntshiv kev loj hlob, kev sib koom ua ke ntawm cov txheej txheem sib koom ua ke, thiab tiv thaiv kev mob ntawm lub tsheb. kev ua haujlwm rov tsim kho dua tshiab hauv kev raug mob kis las-ua kom pom qhov zoo ntawm kev siv tshuab ntau yam.
