As its other names suggest, this chemokine is selectively chemotactic for B cells belonging to both the B-1 and B-2 subsets, and elicits its effects by interacting with chemokine receptor CXCR5.
This chemokine, as suggested by its multiple names, has a particular attraction to B cells from both the B-1 and B-2 categories, and it exerts its influence through interaction with the chemokine receptor CXCR5, which is a key component in the regulation of immune responses.
