The infection is associated with severe pulmonary and systemic manifestations. Previous studies have highlighted the role of fungal proteases in adhesion, invasion, and the modulation of host immune responses, implicating them as key virulence factors. Our group previously demonstrated that\n                    <jats:italic>Paracoccidioides restrepiensis<\/jats:italic>\n                    secretes proteases that activate protease\u2010activated receptors (PAR\u20101 and PAR\u20102) in human lung epithelial cells, stimulating the secretion of proinflammatory cytokines, including IL\u20106 and IL\u20108. We hypothesized that\n                    <jats:italic>P. restrepiensis<\/jats:italic>\n                    secretes proteases that are capable of degrading key host cytokines, such as IL\u20106, thereby contributing to modulate the host immune response during infection. This study is aimed at identifying and characterizing proteases secreted by\n                    <jats:italic>P. restrepiensis<\/jats:italic>\n                    that degrade human IL\u20106. Proteases secreted by\n                    <jats:italic>P. restrepiensis<\/jats:italic>\n                    were isolated using a\n                    <jats:italic>p<\/jats:italic>\n                    \u2010aminomethylbenzamidine (\n                    <jats:italic>p<\/jats:italic>\n                    ABA)\u2010Sepharose affinity column. Protease\u2010containing fractions were incubated with recombinant human IL\u20106 and further analyzed by Western blot to evaluate their ability to degrade this cytokine. Fractions were submitted to liquid chromatography and mass spectrometry to characterize the proteome content, focusing on the identification of fungal proteases. The hydrolysis of IL\u20106 in the presence of different protease inhibitors was also analyzed to confirm the specific activity of the fungal proteases. Enzymatic assays revealed proteases that hydrolyze human IL\u20106, suggesting a mechanism by which\n                    <jats:italic>P. restrepiensis<\/jats:italic>\n                    modulates the host immune response. In addition, mass spectrometry analysis confirmed the presence of a serine protease in the protease activity\u2013containing fractions.
