摘要

To study whether cerebral mycobacterial infection induces granuloma and protective immunity similar to systemic infection, we intracerebrally infected mice with Mycobacterium bovis bacilli Calmette-Guerin. Granuloma and IFN-gamma(+)CD4(+) T cell responses are induced in the central nervous system (CNS) similar to periphery, but the presence of IFN-gammaIL-17 double-positive CD4(+) T cells is unique to the CNS. The major CNS source of TNF-alpha is microglia, with modest production by CD4(+) T cells and macrophage. Protective immunity is accompanied by accumulation of Foxp3(+)CD4(+) T cells and PD-L2(+) dendritic cells, suggesting that both inflammatory and anti-inflammatory responses develop in the CNS following mycobacterial infection.
