Description
Background information
The CD3 antibody (OKT3) recognizes the human CD3 antigen which is expressed on mature T cells, thymocytes and NKT cells. CD3 is associated with the T cell receptor (TCR) and induces the signaling cascade for effector functions of the T cell.
Activation and proliferation of T cells can be induced by interaction of the T cell receptor (TCR) with peptide-MHC complexes expressed on the surface of antigen presenting cells (APC). T cell activation can also be achieved by agonistic stimulation with the CD3 antibody binding to the TCR complex.
Applications
The antibody is suitable for ex vivo T cell activation and expansion and is already established in a variety of clinical protocols for ex vivo T cell stimulation. For example, the transduction of T cells with viral vectors requires the previous activation, which can be achieved by stimulation with CD3 antibody1,2. Furthermore, T cell subsets, such as tumor infiltrating lymphocytes (TILs) can be expanded3, or T cells polyclonally activated by CD3 stimulation.
The CD3 antibody can be combined with CD28 antibody, which gives an additional costimulatory stimulus4.
