Novel interactions of neutrophils with other immune cells. (A) Neutrophils (PMN) accumulate in the splenic marginal zone upon microbial challenge and facilitate the antibody production and maturation of marginal zone B cells (MZB) in response to T cell–independent (TI) antigens. (B) Neutrophils participate in a vicious cycle during autoimmune disease (e.g., SLE) pathogenesis by releasing NETs that trigger pDCs to release IFN-α, which then promotes antibody production by B cells (B). (C) Neutrophils may directly present antigens to T cells (T) and they also activate DCs and deliver antigens to them. (D) Neutrophils and DCs jointly activate NK cells (NK).
