Biochem/physiol Actions

IDR-1 is an anti-infective peptide that acts on the host to stimulate the innate immune response.
IDR-1 is an anti-infective peptide that acts on the host to stimulate the innate immune response. IDR-1 is believed to act by enhancing monocyte chemokines, while reducing pro-inflammatory cytokines (decreased TNF and IL-6 and increased IL-10).

Emily Turner-Brannen et al.
Arthritis research & therapy, 13(4), R129-R129 (2011-08-13)
Innate defence regulator (IDR) peptides are synthetic cationic peptides, variants of naturally occurring innate immune effector molecules known as host defence peptides. IDR peptides were recently demonstrated to limit infection-associated inflammation selectively without compromising host innate immune functions. This study
