CD40–CD40L信号通路研究用产品

CD40是由抗原呈递细胞(APC)和B细胞表达的TNF受体家族的成员,而其配体CD40L(CD154)由活化的T细胞表达。 CD40-CD40L之间的相互作用刺激B细胞的细胞因子分泌,并活化T细胞和抗肿瘤免疫。CD40-CD40L通路的T细胞致敏效应有望成为抗癌免疫疗法中的有效方法。

◆高效B细胞激活剂和T细胞致敏(priming)试剂

CD40激活工具可用于扩增B细胞。作为抗原呈递细胞(APCs),B细胞与树突细胞一样有效,并有望简化抗肿瘤CD8+ T细胞的产生。大量研究表明,激动性抗CD40抗体(FGK45)(产品编号:AG-20B-0036PF)和MultimericCD40L(产品编号:AG-40B-0010)是抗肿瘤免疫的强激活剂。
