IFNA1 and leishmaniasis: Gudmundsdottir et al. (1999) demonstrated that IFN-ɣ production in a murine model is strongly related with cellular division (Gudmundsdottir et al., 1999), as well as Keshavarz Valian et al. (2013) who described in humans infected with leishmaniasis that cells that had more division cycles expressed higher IFN-ɣ levels compared with low division ones (Keshavarz Valian et al., 2013).
