Infection with Paracoccidioides brasiliensis induces B-1 cell migration and activation of regulatory T cells


Paracoccidioidomycosis is a systemic mycosis endemic to Latin America. The infection is initiated by inhalation of conidia into the lung and may develop as localized or disseminated disease depending on the depression of cellular immunity. In the present study, we observed that intratracheal infection with P.b. caused the percentage of resident B-1 cells to decrease. Using xid mice reconstituted with B-1 cells, we observed that B-1 cells migrate to the spleen and stimulate increases in the regulatory T cell subpopulation in response to P.b.
