The B cell helper side of neutrophils.

Neutrophils use opsonizing antibodies to enhance the clearance of intruding microbes. Recent studies indicate that splenic neutrophils also induce antibody production by providing helper signals to B cells lodged in the MZ of the spleen. Here, we discuss the B cell helper function of neutrophils in the context of growing evidence indicating that neutrophils function as sophisticated regulators of innate and adaptive immune responses.
