Interleukin-12 receptor β1 deficiency predisposing to disseminated Coccidioidomycosis

Donald C Vinh et al. Clin Infect Dis. 2011.

Abstract

Severe disseminated Coccidioides is rare while localized, contained disease is common. We report a family with disseminated coccidioidomycosis due to a novel homozygous C186Y mutation in interleukin (IL)-12 receptor β1. This family confirms the centrality of the IL-12/IFN-γ axis to human immunity to Coccidioides spp.

C, Offset histograms showing progressive STAT4 phosphorylation in response to added IL-12 (isotype control [bottom], 0, 2.5, 5, and 10 [top] ng/mL, respectively). D, Activated T lymphocytes from patient 1 failed to express IL-12Rβ1 on the cell surface. E, Phosphorylation of STAT4 is absent in lymphocytes from patient 1 at the same IL-12 doses used in C.
