Description
The TKS-1 antibody reacts with 4-1BB Ligand (4-1BBL), a 97kDa member of the NGF/TNF superfamily which is present on antigen-presenting cells and activated B lymphocytes. 4-1BBL interacts with 4-1BB (CDw137), found predominantly on activated T lymphocytes. This ligand-receptor pair is grouped with pairs such as CD27/CD70, CD30/CD153, OX-40/OX-40L, CD80/CD28, and CD86/CD28, which costimulate T-cell proliferation and cytokine production. The interaction of 4-1BB with 4-1BBL may be reciprocally costimulatory in that 4-1BBL may deliver proliferative signals to B lymphocytes activated by anti-IgM. The TKS-1 mAb stains B cells activated for three days with anti-IgM polyclonal antibody, consistent with an earlier report that soluble 4-1BB-alkaline phosphatase fusion protein binds to anti-IgM-activated B cells. Furthermore, 4-1BBL mRNA has been detected in activated T lymphocytes and activated macrophages. The TKS-1 mAb has been reported to inhibit the binding of soluble 4-1BB to 4-1BBL transfectants and block the in vitro costimulation of T-lymphocyte proliferation by 4-1BBL transfectants.
