CXCR5 and infection: The requirement for effective Th2 priming by CXCR5‐expressing cDC is not restricted to T. muris infection, as a similar requirement during infection with H. polygyrus and the intracellular parasite Leishmania major has been described.21 A thorough understanding of the role of CXCR5‐expressing cDC in the induction of Th2 responses may identify novel therapeutic targets to enhance immunity to helminths or modulate the pathology caused by certain allergic inflammatory diseases.
