In this study, we determined the effects of glutathione (GSH)-enhancing agents in restoring the levels of GSH in isolated macrophages from individuals with HIV infection thereby resulting in improved control of Mycobacterium tuberculosis. Our results indicate that treatment with N-acetyl cysteine or a liposomal formulation of glutathione (lGSH) resulted in replenishment of reduced also known as free GSH (rGSH), and correlated with a decrease in the intracellular growth of M. tuberculosis. Finally, we observed differences in the amount of the catalytic subunit of glutamine-cysteine ligase (GCLC), glutathione synthase, and glutathione reductase present in macrophages derived from healthy and HIV-infected individuals. These changes correlated with changes in free radicals as well as rGSH levels. Our results indicate that HIV infection leads to increased production of free radicals and decreased production of GCLC resulting in depletion of rGSH and this may lead, in part, to the loss of innate immune function observed in HIV patients. These findings represent a novel mechanism for control of M. tuberculosis infection, and a possible supplement to current HIV treatments.

This article reports in silico analysis of methyl isocyanate (MIC) on different key immune proteins against Mycobacterium tuberculosis. The analysis shows that MIC is released in the Bhopal gas tragedy in 1984, which is highly toxic and extremely hazardous to human health. In this study, we have selected immune proteins to perform molecular docking with the help of Autodock 4.0. Results show that the CD40 ligand and alpha5beta1 integrin have higher inhibition compared to plasminogen activator urokinase, human glutathione synthetase, mitogen-activated protein kinase (P38 MAPK 14), surfactant protein-B, -D (SP-D), and pulmonary SP-D. MIC interacted with His-125, Try-146 residue of CD40 ligand and Ala-149, and Arg-152 residue of alpha5beta1 integrin and affects the proteins functioning by binding on their active sites. These inhibitory conformations were energetically and statistically favored and supported the evidence from wet laboratory experiments reported in the literature. We can conclude that MIC directly or indirectly affects these proteins, which shows that survivals of the disaster suffer from the diseases like tuberculosis infection and lung cancer.
