Fig. 1From: Interleukin 6 and interferon gamma haplotypes are related to cytokine serum levels in dogs in an endemic Leishmania infantum regionSerum levels of cytokines in Boxer (B) and Ibizan hound (I). Different P-values for cytokines are shown in figures a–e. a Interferon gamma (IFN-γ), b Interleukin 2 (IL-2), c Interleukin 6 (IL-6), d Interleukin 8 (IL-8), and e Interleukin 18 (IL-18). Squares represent LS means values for two breeds, and vertical lines represent standard deviation. Values for IL-8 and IL-18 are expressed in pg/ml, and for IFN-γ, IL-2, and IL-6 in ng/ml.
