[12] demonstrated that in HIV-positive patients, the level of IL-6 significantly increased while the levels of free radicals increased due to significant reduction of GSH levels, and the introduction of liposomal GSH (L-GSH) was able to significantly increase the levels of GSH in the patients CD4+ T cells
Methionine sulfoxide can be subsequently reduced back to methionine by specific reductases, thereby restoring A1ATs functionality and enabling continuous ROS scavenging ( Beside the described scavenging effect, however, oxidation of methionine residues leads to a decrease in the protective effect of A1AT as a protease inhibitor ( For this reason, an increasing number of studies reports the development of engineered forms of A1AT, with amino acid substitution at methionine 351 and 358, designed to keep the anti-protease activity, even in a oxidative microenvironment ( Additionally, the cysteine residues in A1AT may undergo oxidation, which decreases ROS levels
