These potential phosphorylation sites may be important for intracellular signaling events and/or extracellular molecular interactions
These potential phosphorylation sites may be important for intracellular signaling events and/or extracellular molecular interactions. anti-CD99 monoclonal antibody was observed. == Conclusions == We provide evidence that CD99 directly interact and form the complex with the MHC Loratadine class Loratadine I and II, and tetraspanin CD81, and is functionally linked to the formation of the immunologic synapse. Upon T cell activation, CD99 Loratadine engagement can inhibit T cell proliferation. We speculate the CD99-MHC-CD81 complex is a tetraspanin web that plays an important part in T cell activation. == Background == Upon T cell activation, T cell activation is initiated when a T cell receptor (TCR) encounters specific antigen peptide-MHC complexes indicated on the surface of antigen showing cells (APCs). The connection of various co-stimulatory molecules indicated on T cells and…
