Edratide (TV 4710) is a synthetic peptide of 19 amino acid based on the complementarity-determining region 1 (CDR1) of a human anti-DNA antibody that expresses a major idiotype denoted 16/6 Id. Edratide reduces the rates of apoptosis (Apoptosis) and down-regulates of caspase-8 and caspase-3, up-regulates Bcl-xL. Edratide has the potential for the research of systemic lupus erythematosus (SLE).
