[Leu144,Arg147]-PLP (139-151)是髓鞘脂蛋白(PLP)的一种突变肽段,包含位于144和147位置的色氨酸到亮氨酸以及组氨酸到精氨酸的替换。使用[Leu144, Arg147]-PLP (139-151)(50 µg)乳化于完全弗氏佐剂(CFA)免疫后,能增加小鼠脾脏中的IL-4水平。它在体外抑制Th1细胞激活,但在体内不抑制,其中它诱导调节性T细胞的产生。用[Leu144, Arg147]-PLP (139-151)预免疫可以延迟由脑炎肽PLP (178-191)、髓磷脂少突细胞蛋白(MOG) (92-106)或髓鞘基础蛋白(MBP)在小鼠中诱导的实验性自身免疫性脑炎(EAE)的发病。

产品描述 | [Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund’s adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice. |
