背景介绍
Cluster of differentiation 40 (CD40) is a costimulatory protein located on antigen presenting cells and is required for their activation. CD40 is a member of the tumor necrosis factor (TNF) receptor (TNFR) family.
What is the molecular weight of CD40?
The molecular weight of CD40 is 43 kDa.
What is the cellular localization of CD40?
CD40 can be secreted by cells or found in the cell membrane.
What is the tissue specificity of CD40?
CD40 is expressed in B cells and primary carcinoma cells but is also found in dendritic cells and macrophages (PMID: 10209159).
What is the function of CD40?
CD40 acts as a receptor for TNFSF5/CD40LG, which is expressed on activated T cells. This interaction is essential for B cell proliferation, expression of activation markers, immunoglobulin production, and isotype switching (PMID: 8809473). This interaction is also crucial for the formation of memory B cells and germinal centers, and signaling through CD40 prevents apoptosis of germinal center B cells.
What is the role of CD40 in disease?
Defects in CD40 lead to hyper-IgM immunodeficiency syndrome type 3 (HIGM3) (PMID: 11675497). This is an autosomal recessive disorder that includes the inability of B cells to undergo isotype switching, a key step in the final differentiation of the humoral immune response, and an inability to mount an antibody-specific immune response.

细胞激活；④通过转基因表达CD40L的成纤维细胞。也能刺激B细胞；⑤CD40或CD40L基因敲除的小鼠，抗体产生形成的缺陷类似人类的X性联高IgM血症，患者只产生了IgM，而无其他类别的抗体，也无生发中心，抗感染能力明显下降。 CD40与其配体CD401。的结合，导致CD40分子的寡聚化，使胞质中的TNF受体相关因子(TNF receptor-associ-atedfactor，TRAF)与CD40的胞内结构域结合。TRAF参与启动的酶催化级联反应，最终导致转录因子NFκB和AP-1等活化。
