MeSH Heading: Thymalfasin
Tree Number(s): D06.472.910.850.500; D12.644.548.869.500; D12.776.922.500
Unique ID: D000077596
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000077596
Scope Note: A thymus hormone polypeptide found in thymosin fraction 5 (a crude thymus gland extract) but now produced by synthesis. It is used alone or with interferon as an immunomodulator for the treatment of CHRONIC HEPATITIS B and HEPATITIS C. Thymalfasin is also used for the treatment of chemotherapy-induced immunosuppression, and to enhance the efficacy of influenza and hepatitis B vaccines in immunocompromised patients.
