pubmed:abstractText |
Millions of people harbor latent infections of the fungus Histoplasma capsulatum. Such persistent infections represent a stalemate between mechanisms of virulence and the immune response. The differing responses of inbred mouse strains to the same pathogen reflect variation in the genes that control the outcome of infection. Here we show that a 250-fold difference in H. capsulatum susceptibility between inbred mouse strains is attributable to the genotype at the MHC H2 locus. Gene expression analysis of strains varying only at the H2 locus identified genotype-specific and genotype-independent expression signatures, including infection-induced genes such as the fungal pattern recognition receptor Clec7a. Surprisingly, B-cell-specific gene expression was negatively correlated with fungal burden, whereas neutrophil-specific genes were correlated with superior disease outcome. Indeed, disease outcome improved when B cells were eliminated and neutrophils were more active, a previously unknown aspect of the host response. These data refine the understanding of genetic influences on histoplasmosis, reveal how shifts in the composition of immune cell populations compel different disease outcomes, and uncover how innate immunity modulation alters histoplasmosis.
