Endogenous Interleukin-12 regulates macrophage phagocytosis of Sporothrix schenckii
Resumen
Context: Sporothrix shenckii is a widespread dimorphic fungus that causes sporotrichosis, an acute and chronic infection of the skin and subcutaneous tissues. It displays a range of clinical forms from fixed cutaneous to systemic infection[1]. Systemic sporotrichosis occurs mainly in immunodeficient patients and can be potentially fatal [2]. In the host defense against S. schencki, macrophages play an important role [3-5] through both phagocytosis and oxidative processes
