Role of B Cells in Vaccine-Induced Immunity against Coccidioidomycosis

We investigated secondary immunity against coccidioidomycosis by using gene expression microarrays. Surprisingly, a high percentage of B-cell-related genes were associated with protective immunity. A functional confirmation of the importance of B cells against coccidioidomycosis was achieved by demonstrating that vaccination was not fully protective in B-cell-deficient MuMT mice.
