系統詳細
The CD40 gene encodes CD40, a transmembrane protein belonging to the tumor necrosis factor receptor (TNFR) superfamily. Primarily expressed on antigen-presenting cells (APCs) such as B lymphocytes, macrophages, and dendritic cells, CD40 is also found on a variety of non-immune cells including endothelial cells, fibroblasts, epithelial cells, and smooth muscle cells, as well as many tumor cells [1]. The CD40LG gene is located on the X chromosome (Xq26.3) and encodes CD40 ligand (CD40L, also known as CD154), a type II transmembrane protein mainly expressed on activated T cells, platelets, and some B cells. Under inflammatory conditions, monocytes, natural killer cells, mast cells, and basophils can also be induced to express CD40L [2-4].
The interaction of CD40 with its ligand, CD40L (CD154), is a critical costimulatory signal essential for T-dependent humoral and cell-mediated immunity. This interaction triggers downstream signaling pathways, including NF-κB, JNK, and JAK/STAT, leading to B cell activation, proliferation, differentiation, isotype switching, memory B cell development, germinal center formation, and enhanced APC function and cytokine production [5]. Dysregulation of CD40/CD40L signaling pathway is implicated in the pathogenesis of numerous diseases, including autoimmune disorders like inflammatory bowel disease (IBD), type 1 diabetes (T1D), multiple sclerosis, and rheumatoid arthritis (RA), as well as cardiovascular diseases such as atherosclerosis, certain neurological conditions including Alzheimer's disease (AD) and traumatic brain injury, and various cancers [5-7].
Due to the important role of the CD40/CD40L interaction in immune activation, CD40/CD40L has been an important target for immunotherapy. In recent years, significant progress has been made in CD40/CD40L-targeted therapy. Various drugs have been developed, including agonistic/antagonistic monoclonal antibodies, cellular vaccines, adenoviral vectors, and protein antagonists, and have shown therapeutic potential in malignant tumors, autoimmune diseases, and allograft rejection [1].
The B6-hCD40/hCD40LG mouse is a dual-gene humanized model (for CD40 and CD40LG) generated by crossing B6-hCD40 mice (Catalog No.: C001721) with B6-hCD40LG mice (Catalog No.: C001720). The B6-hCD40/hCD40LG mouse model can be used for research on the mechanisms and therapeutic approaches of diseases such as autoimmune diseases, cancer, and cardiovascular diseases, as well as for the development of CD40/CD40L-targeted drugs.
