My laboratory studies the pathophysiology of tuberculosis in the context of HIV co-infection and type II diabetes. We are pioneers in reporting that glutathione (GSH) has both antimycobacterial effects and immune enhancing effects and is necessary for the control of Mycobacterium tuberculosis (Mtb) infection. We also reported that the levels of GSH were significantly compromised in macrophages, natural killer (NK) cells and T cells derived from individuals with HIV infection. Decreased levels of GSH in individuals with HIV infection was accompanied by diminished control of intracellular Mtb infection. We then demonstrated that the levels of enzymes that are responsible for the synthesis of GSH such as GSH synthase (GSS), g-glutamyl cysteinyl ligase (GCLC), and GSH reductase (GSR) were significantly reduced in individuals with HIV infection and this reduction correlated with decreased levels of intracellular GSH. We recently conducted a clinical trial in HIV positive individuals to test the efficacy of liposomal glutathione (L-GSH) in restoring the levels of GSH and improving the functions of immune cells. Findings from this study indicate a link between lower levels of GSH and dysregulation in the production of TH1 and TH2 associated cytokines. Furthermore, supplementing individuals with HIV infection for 13 weeks with L-GSH resulted in a significant increase in the levels of TH1 cytokines (IL-1ß, IL-12, IFN-y and TNF-a) along with a substantial decrease in the levels of free radicals and immunosuppressive cytokines (IL-10 and TGF-ß), relative to those in a placebo-controlled cohort. Our studies established a correlation between low levels of GSH and increased susceptibility to Mtb infection via TH2-directed response, which may be relieved with L-GSH supplementation enhancing the TH1 response. I look forward to continuing this important research work (preclinical and clinical studies) and develop immunotherapeutic agents that can be used as adjunct to prevent the development of active tuberculosis in individuals with HIV infection and in people with type II diabetes.
