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) . In Vivo Edratide (20-50 µg; s.c.; once a week for 10 weeks) exerts beneficial effects on SLE is through regulation of gene expression. Edratide (50 μg/mouse; s.c.; 10 weekly) reduces the rates of apoptosis and down-regulates of caspase-8 and caspase-3, up-regulates Bcl-xL in SLE mouse. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: 6-7 months female mice (with established SLE)Dosage: 20-50 µg Administration: Subcutaneously injection; once a week for 10 weeks Result: Up-regulated the RNA transcripts of Tnfsf4, Il5ra, Zbtb20, Nid1, down-regulated the transcripts of Tfpi and S100a8. Animal Model: 7-8 months SLE-afflicted BWF1 female miceDosage: 50 μg/mouse Administration: S.c.; 10 weekly Result: Reduced apoptosis, down-regulated caspase-8 and caspase-3, and up-regulated Bcl-xL.
