Absence of neutrophils impairs the host defense in murine footpad model of chromoblastomycosis.

ABSTRACT: Chromoblastomycosis (CBM), a chronic subcutaneous infection caused by black fungi such as Fonsecaea monophora (F. monophora), is characterized by a low cure rate, high recurrence rate, and prolonged treatment duration. Neutrophils, one of the most important innate immune cells, play complex roles in the prevention of fungal infections. This study investigated the function of neutrophils in host defense against F. monophora using a neutrophil-depleted mouse model and in vitro co-culture conditions. Fungal burden, histopathological changes, and cytokine profiles were compared between neutrophil-depleted mice and isotype control mice. Our findings demonstrated that neutrophil depletion in mice led to impaired fungal clearance, prolonged inflammation in F. monophora infected footpad tissues, h
