  • Tool name: CHEC-9 immunomodulatory Peptide
  • Alternate name: Human neuroprotective polypeptide Diffusible Survival Evasion Peptide (DSEP)
  • Research fields: Immunology;Neurobiology
  • Sequence: CHEASAAQC
  • Description: The CHEC-9 (peptide sequence CHEASAAQC) sequence is a fragment of a human diffusible survival evasion peptide (DSEP). CHEC-9 is an anti-inflammatory/neuroprotective peptide that uncompetitively binds and inhibit secreted phospholipase A2 (sPLA2). Allowing for the study of PLA2-directed inflammation of traumatic and autoimmune (Autoimmune Myeloencephalitis) neurodegenerative disorders. CHEC-9 also binds HSP70 and may influence HSP70-dependent dissolution of protein aggregates that accumulate in aging and disease models like Parkinson’s and Alzheimer’s Disease.
