生物活性

Cinnamtannin D1 is an orally active polyphenolic compound with immunosuppressive activity. Cinnamtannin D1 regulates the balance of Th17/Treg cells by inhibiting AHR expression. Cinnamtannin D1 reduces apoptosis and ROS in INS-1 cells and primary cultured murine islets induced by Palmitic acid (PA) (HY-N0830). Cinnamtannin D1 reduces Th17 cell differentiation via downregulating p-STAT3/RORγt and promotes Treg cell differentiation via upregulating p-STAT5/Foxp3. Cinnamtannin D1 exerts excellent anti-arthritic efficacy in collagen-induced arthritis (CIA) model of mice. Cinnamtannin D1 can be used for the study of rheumatoid arthritis (RA)[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
