CD40LG and parasitic infectious disease: This can lead to (a) improved B cell survival, (b) IgM antibody secretion, (c) IgG and IgA isotype switching and (d) somatic hypermutation induction.27 Finally, neutrophils can positively regulate antigen‐specific T cell responses and can act as antigen‐presenting cells.28, 29 Collectively, these neutrophil effector functions could all contribute to parasitemia control by triggering both innate and adaptive defence responses.
