Ac2-26 TFA
Based on 8 publication(s) in Google Scholar
Ac2-26 TFA is the N-terminal peptide of annexin 1, and has anti-inflammatory activity. Ac2-26 induces a decrease in IKKβ protein in lysosomes by chaperone-mediated autophagy (CMA). Ac2-26 ameliorates lung ischemia-reperfusion injury. Ac2-26 also inhibits airway inflammation and hyperresponsiveness in an asthma rat model.
