- Abstract
Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungus within the genus Paracoccidioides, particularly Paracoccidioides brasiliensis. The traditional approach to treating this pulmonary infection involves prolonged therapy periods, ranging from weeks to years, often resulting in a notable frequency of disease relapse. Nanotechnology has emerged as a promising avenue for developing novel antifungal therapies and effective vaccines. This is attributed to its capability to facilitate targeted drug and antigen delivery, thereby mitigating toxicity and treatment expenses. This study investigates the synergistic properties of the CHO-rPb27 vaccine nanoformulation against experimental PCM. The therapeutic efficacy of CHO-rPb27 treatment is juxtaposed with the prophylactic protocol. Our findings demonstrate that both protocols effectively control P. brasiliensis pulmonary infection by eliciting a robust cellular and humoral immune response. This response attenuates chronic tissue damage and mitigates pulmonary mechanical dysfunction in mice., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024.
