半岛bd体育手机客户端 说明
一般描述
CD5 (cluster of differentiation 5) is a lymphocyte surface receptor. It is expressed by all T cells and the B1a subset of mature B cells (participating in the generation of low-affinity polyreactive antibodies). The CD5 gene is mapped to human chromosome 11q12.
Recombinant human CD5 protein, fused to His-tag at N-terminus, was expressed inEscherichia coli.
生化/生理作用
CD5 (cluster of differentiation 5) is required for fine tuning of TCR (T-cell receptor) signaling. It also controls activation-mediated T cell death and recognizes pathogen-associated molecular patterns. In T and B1 cells, CD5 negatively regulates the signaling by clonotypic antigen-specific receptor. CD5 is present in patients with rheumatoid arthritis, systemic lupus erythematosus, Sj?gren syndrome, Grave′s Basedow thyroiditis and type 1 diabetes mellitus. In infants, high levels of CD5+cells suggest the risk of development of allergic disease. The gene is also associated with peripheral T-cell lymphoma and mature B-cell neoplasms (mainly chronic lymphocytic leukemia and mantle cell lymphoma).
