Resumo
O objetivo deste estudo foi avaliar a influência da testosterona sobre a atividade funcional de macrófagos murinos residentes frente ao Trichophyton mentagrophytes. Nas condições ensaiadas, a testosterona influenciou a liberação da H2O2 levando a redução da atividade microbicida dos macrófagos, facilitando o crescimento e diferenciação dos conídeos fagocitados.
