Coffee's Protective Signal May Not Be Caffeine
Laboratory models link caffeic acid and other coffee compounds to the stress-responsive receptor NR4A1.
Summary
Laboratory models link caffeic acid and other coffee compounds to the stress-responsive receptor NR4A1.
Texas A&M researchers found that several coffee compounds bind to and alter the activity of NR4A1, a nuclear receptor involved in inflammation, metabolism, and tissue repair. Polyphenolic compounds such as caffeic acid were more active in the models than caffeine, and protective cell effects disappeared when NR4A1 was removed. The work proposes a mechanism for prior population associations; it does not prove that coffee prevents disease in people or change drinking recommendations.
