IRBP651-670(Interphotoreceptor retinoid-binding protein (651-670))是IRBP(亦称为retinoid-binding protein 3)的肽段,参与色素再生,通过将视黄醇和视黄醛从光感受细胞传输到视网膜色素上皮。在C57BL/6小鼠中,利用IRBP651-670诱导自身免疫性葡萄膜炎,这些小鼠携带H-2b单体型。用IRBP651-670(300 µg/动物)免疫增加了小鼠眼部IL-1β、IL-6、IL-17、TNF-α和IFN-γ水平,免疫细胞浸润及光感受器损伤。
Body Protection Compound 157 (BPC 157) is a pentadecapeptide derived from BPC, identified in gastric juice, exhibiting diverse biological activities. At 2 µg/ml, BPC 157 enhances primary rat tendon fibroblast cell migration and F-actin formation. Furthermore, doses of 0.01 and 10 µg/kg, intraperitoneally (i.p.), mitigate paw swelling, bone erosion, and mononuclear cell infiltration in the joints of rats with rheumatoid arthritis induced by complete Freund's adjuvant (CFA). It also diminishes gastric ulcer size in rats caused by indomethacin, aspirin, or diclofenac at these doses. Additionally, BPC 157 reduces catalepsy duration and tremor severity in a mouse model of Parkinson's disease triggered by MPTP.
MACTIDE-V 是一种口服活性和选择性的肽-药物偶联物,靶向CD206。它将Verteporfin 递送至 CD206+ 肿瘤相关巨噬细胞 (TAM),通过抑制YAP/TAZ信号通路,促使YAP从细胞核中排除,诱导 TAM 偏向抗肿瘤表型,增强其吞噬和抗原呈递功能,并促进 T 细胞浸润和 NK 细胞活性。MACTIDE-V 有效抑制三阴性乳腺癌 (TNBC) 小鼠模型的原发肿瘤生长及肺转移。
