Concentrations of IFN‐γ peak on the day of treatment or soon after, correlating with parasitemia.59, 60, 61, 62, 63, 64, 65, 66 IFN‐γ also enhances expression of CXCL965, 66, 67 and release of soluble granzyme A and B,59 suggesting enhancement of cytotoxic cell activity. Here, IFNG is linked to parasitic infectious disease.
