PG - 1095-104 AB - Mycobacterial infections are critically controlled by interferon-gamma (IFN-gamma) and the cellular responses it elaborates, as shown by patients with mutations in the IFN-gamma receptor ligand-binding chain (IFN-gamma R1) who have disseminated nontuberculous mycobacterial infections. The immunologic sequelae of IFN-gamma R1 deficiency were characterized in 2 unrelated patients from the Indian subcontinent with novel homozygous recessive IFN-gamma R1 mutations. In vitro, these patients' peripheral blood mononuclear cells produced 10% of normal IFN-gamma and interleukin-12 (IL-12) in response to phytohemagglutinin (PHA) but normal amounts of IFN-gamma in response to PHA plus IL-12. Tumor necrosis factor-alpha (TNF-alpha) production was normal in response to endotoxin and to PHA but was not augmented by the addition of IFN-gamma. An abnormal phenotype was not found in heterozygous patient relatives. These patients demonstrate the critical role that the IFN-gamma receptor plays in the regulation of IFN-gamma, IL-12, and TNF-alpha.
