功能: Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in co
njunction with TCR/CD3 ligation and CD40L costimulation (PubMed:8617933).
Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells (PubMed:15067037).
产品背景: T-cell-specific surface glycoprotein CD28(CD28) is a single-pass typeI membrane protein which co
ntains one Ig-likeV-type(immunoglobulin-like) domain. It belo
ngs to the immunoglobulin(Ig) superfamily. CD28 is one of the molecules expressed on T cells that provide co-stimulatory signals, which are required for T cell activation. CD28 co-stimulation is necessary for CD4 positive T-cell proliferation and survival, interleukin-2 production, and T-helper type-2 development. Human post-thymic regulatory T cells require CD28 co-stimulation to expand and maintain potent suppressive function in vivo. Apoptosis plays a key role in the age-related decline of CD28 ex
pression and in immunosenescence. CD28 is the receptor for CD80(B7.1) and CD86(B7.2). When activated by Toll-like receptor ligands, the CD80 ex
pression is upregulated in antigen presenting cells(APCs). The CD86 ex
pression on antigen presenting cells is constitutive. CD28 is the o
nly B7 receptor co
nstitutively expressed on naive T cells.
