peprotech細(xì)胞因子120-30 Human DKK-I重組蛋白*
細(xì)胞因子是一組蛋白質(zhì)及多肽在生物中用作信號(hào)蛋白.這些類似激素或神經(jīng)遞質(zhì)的蛋白用作細(xì)胞間溝通的信號(hào).細(xì)胞因子多是水溶性蛋白和糖蛋白,分子量小(8-30千道耳頓).細(xì)胞因子可以由多種細(xì)胞釋放,尤其重要的是在先天性免疫反應(yīng)和適應(yīng)性免疫反應(yīng).由于其免疫系統(tǒng)中的作用,細(xì)胞因子參與免疫性疾病.炎癥及傳染性疾病.不過(guò),并非所有的功能*于免疫系統(tǒng),細(xì)胞因子還涉及多個(gè)胚胎發(fā)育環(huán)節(jié).
