Definitions
- T cell receptors are members of the immunoglobulin superfamily and usually consist - -subunits.
- TCRs are thought to recognize the MHC.
- the constant domain of the TCR domain consists of short connecting sequences in which a cysteine residue forms disulfide bonds, which forms a link between the two chains.
- the affinity of TCRs for a specific antigen makes them valuable for several therapeutic approaches. For example, cancer patients, such as melanoma patients, can be effectively treated by using adoptive immunotherapy as TCRs areakily sensitive for their antigen and can direct immune responses at tumor cells expressing their cognate antigen. Accordingly, there is a need for TCRs against peptide- MHC complexes for development of new and effective therapeutics.
