span style= font-family:Times,serif;font-size:9pt; The CD282 monoclonal antibody specifically binds to CD28, a 44 kDa homodimeric transmembrane glycoprotein present on most mature T cells, thymocytes and plasma cells CD28 is a costimulatory receptor that binds CD80 and CD86 as ligands and plays a very important role in T cell-B cell interactions It has been suggested that CD28 initiates and regulates a separate and distinct signal transduction pathway from those stimulated by the TCR complex Additionally, it has been reported that CD28 antibody clones vary in their ability to stimu

Whereas co-stimulation of the T-cell antigen receptor (TCR) and CD28 triggers T-cell activation, stimulation of the TCR alone may result in an anergic state or T-cell deletion, both possible mechanisms of tolerance induction1,2 Here we show that T cells that are deficient in the adaptor molecule Cbl-b (ref 3) do not require CD28 engagement for interleukin-2 production, and that the Cbl-b-null mutation (Cbl-b-/-) fully restores T-cell-dependent antibody responses in CD28-/-mice The main TCR signalling pathways, such as tyrosine kinases Zap-70 and Lck, Ras/mitogen-activated kinases, phosp
