It is also hypothesized that the increased production of inflammatory mediators (interleukin-1α [IL-1α], IL-1β, IL-2, IL-4, IL-6, IL-10, IL-12, gamma interferon [IFN-γ], and tumor necrosis factor alpha [TNF-α]) in infected skin cells caused by Melassezia furfur, and the Malassezia genus in general, may play a role.
