Core Application Areas
1. Txoj Cai Tiv Thaiv Kab Mob: Hloov Kho Lub Cev Lub Cev Lub Cev Muaj Zog Sib Nqus
Cov tshuaj Peptide ua tiav cov kev cai bidirectional ntawm kev siv thiab kev coj ntawm lub cev tiv thaiv kab mob los ntawm kev hloov kho qhov sib txawv, kev loj hlob, thiab kev ua haujlwm ntawm lub cev tiv thaiv kab mob.
Kev tswj hwm ntawm T cell subsets
Peptides xws li TA1, raws li bioactive peptides muab tau los ntawm thymus, feem ntau txhawb kev loj hlob ntawm T cell precursors rau hauv cov T cells ua haujlwm, pab txhawb kev sib koom ua ke ntawm CD4⁺ pab T hlwb thiab CD8⁺ cytotoxic T hlwb. Los ntawm activating intracellular signaling pathways, cov peptides txhim kho cov antigen paub peev xwm ntawm T hlwb, txhawb cytokine secretion, thiab txhim khu lub cev efficiency ntawm clearing pathogens thiab txawv txav hlwb, ua rau lawv tsim nyog rau kev tiv thaiv kab mob nyob rau hauv immunocompromised cov neeg thiab adjuvant cancer kho.
Regulatory T cell-inducing peptides
Cov peptides luv luv muab tau los ntawm tib neeg cov proteins tuaj yeem xaiv ua kom muaj kev loj hlob ntawm kev tswj T hlwb (Tregs) thiab inhibit overactivated effector T cells. Cov Tregs no tswj kev tiv thaiv kab mob hauv lub cev tsis kam lees thiab kab mob autoimmune los ntawm secreting inhibitory cytokines txhawm rau txhawm rau tiv thaiv kev tiv thaiv ntau dhau.
Txhim kho cov haujlwm hauv lub cev tiv thaiv kab mob
Antimicrobial peptides (AMPs) xws li LL37 nthuav tawm ob txoj haujlwm ntawm cov tshuaj tiv thaiv kab mob thiab kev tiv thaiv kab mob. Lawv ncaj qha ua rau cov kab mob hauv cov kab mob rau cov kab mob bactericidal thiab induce dendritic cell maturation, txhawb kev nthuav qhia antigen thiab T cell activation, yog li ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob ntawm lub cev tiv thaiv xws li daim tawv nqaij thiab mucosa.

2. Inflammation Alleviation: Multi-pathway Blockade of Inflammatory Cascades
Targeting cov nodes tseem ceeb ntawm cov inflammatory teb, peptide tshuaj exert los ntawm inhibiting pro-inflammatory signals, txhawb anti-inflammatory mediator ntau lawm, thiab kho cov ntaub so ntswg microenvironment.
Central inhibition ntawm txoj kev NF-κB
Kev tiv thaiv kab mob plab peptides xws li BPC-157 cuam tshuam rau hauv cov khoom siv hluav taws xob nuclear κB (NF-κB) kev taw qhia txoj hauv kev, inhibiting cov ntaub ntawv thiab tso tawm cov pro-inflammatory cytokines thiab txo cov ntaub so ntswg hauv zos inflammatory edema. Tsis tas li ntawd, lawv txhawb kev nthuav qhia ntawm mucosal kho cov kab mob ntsig txog cov noob, ua kom lub cev zoo ntawm cov ntaub so ntswg puas, ua kom pom ob qho kev tiv thaiv kab mob thiab rov kho cov kab mob xws li mob plab hnyuv thiab plab hnyuv.
Kininogen-derived peptides
Peptides xws li KPV tswj kev ua haujlwm ntawm neutrophil thiab adhesion molecule qhia, txo cov infiltration ntawm inflammatory hlwb ntawm qhov chaw raug mob, txo oxidative kev nyuaj siab puas tsuaj, thiab txhim kho lub zos microenvironment. Cov khoom no ua rau lawv tsim nyog rau kev kho mob ntsig txog kab mob xws li ischemia-reperfusion raug mob thiab mob ntshav qab zib ko taw.
Synergistic tswj ntawm mitochondria thiab oxidative kev nyuaj siab
Mitochondria-targeted peptides xws li SS-31 lub hom phiaj mitochondrial membrane cov qauv, tiv thaiv mitochondrial kev ua haujlwm ncaj ncees, txo qis ntau cov pa oxygen ntau ntau (ROS) ntau lawm, thiab inhibiting apoptosis teeb liab ua kom. Qhov no alleviates oxidative stress-induced cov ntaub so ntswg puas thiab muab kev tiv thaiv lub cev nyob rau hauv lub plawv o thiab neurodegenerative kab mob.
3. Adjuvant Therapy for Autoimmune Diseases: Reconstructing Immune Tolerance Microenvironment
Lub hom phiaj ntawm kev tawm tsam tsis ncaj ncees ntawm kev tiv thaiv kab mob ntawm tus kheej hauv cov kab mob autoimmune, cov tshuaj peptide tawm dag zog kho cov teebmeem los ntawm kev tswj hwm lub cev tiv thaiv kab mob thiab cov haujlwm ua haujlwm.
Antigen tshwj xeeb tiv thaiv kab mob induction
Cov peptides luv luv muab tau los ntawm tus kheej-antigen epitopes khi rau cov molecules ntawm lub ntsej muag ntawm cov tshuaj tiv thaiv kab mob, ua rau lub cev tiv thaiv kab mob rau tus kheej-antigens. Qhov no txo qis kev tsim cov autoantibodies thiab cov ntaub so ntswg tawm tsam los ntawm effector T hlwb, muab cov phiaj xwm kev cuam tshuam rau cov kab mob xws li mob caj dab rheumatoid thiab kab mob lupus erythematosus.
Balanced kev cai ntawm cytokine network
Qee cov peptides modulate qhov sib txawv ntawm Th1 / Th2 / Th17 cell subsets thiab cytokine secretion qauv, inhibiting ntau tshaj tawm ntawm pro-inflammatory yam thiab txhawb zus tau tej cov anti-inflammatory cytokines. Qhov no alleviates inflammatory teb nyob rau hauv cov kab mob autoimmune thiab txhim kho cov ntaub so ntswg puas.
