Neutrophils may be also implicated in immunoregulation as a source of cytokines, such as interleukin-2 (IL-12), interleukin-10 (IL-10), gamma interferon (IFN-γ) and TNF-α [1], [2], thus establishing a link between innate and adaptative immunity during parasitic infection [3], [4]. Here, IFNG is linked to parasitic infectious disease.
