About B7-33

What it is
B7-33 is a single-chain analog of the hormone relaxin, simplified from the natural two-chain structure into one linear peptide that still activates the relaxin receptor RXFP1. It is described as a functionally selective agonist that favors pathways reducing tissue scarring. In rodent models of heart and lung disease it reduced organ fibrosis, supporting interest as an anti-fibrotic agent. It has only been studied in preclinical research.
How it works
It is a single-chain relaxin analog that selectively activates the RXFP1 receptor, favoring signaling that reduces fibrosis.
