Existing proof suggests that chronic inflammation linked with HIV is particularly attributed to the dysregulated production of reactive oxygen species (ROS) that contribute to neurodegeneration and poor clinical outcomes. When ROS have effective effects in eliciting immune responses to infection, chronic ROS production causes damage to macromolecules for instance DNA and lipids that has been linked to altered redox homeostasis connected with antioxidant dysregulation. As a result, this disruption within the balance between antioxidant-dependent mechanisms of ROS inactivation and ROS production by enzymes for example the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase household, too as from the electron transport chain with the mitochondria can result in oxidative strain. This is particularly relevant to the brain, which is exquisitely susceptible to oxidative pressure as a consequence of its inherently high lipid concentration and ROS levels that have been linked to numerous neurodegenerative ailments which have similar stages of pathogenesis to HAND. In this critique, we go over the feasible function and mechanisms of ROS production leading to oxidative strain that underpin HAND pathogenesis even when HIV is suppressed by existing goldstandard antiretroviral therapies. Additionally, we highlight that pathological ROS can serve as biomarkers for HIV-dependent HAND, and how manipulation of oxidative pressure and antioxidant-dependent pathways may perhaps facilitate novel techniques for HIV remedy.1. Background To date, human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) has impacted more than 70 million persons worldwide (Globe Overall health Organisation. Worldwide Overall health Observatory (GHO), 2019). It can be estimated that 38 million people are at present living with HIV/AIDS, with 690,000 individuals getting died of HIV-related illnesses in 2019 alone (Planet Wellness Organisation. Global Overall health Observatory (GHO), 2019). The arrival of antiretroviral therapy (ART) regimens that suppress viral replication has brought regarding the transformation of HIV/AIDS from a progressive and fatal illness to one that may be chronic but manageable. Having said that, no scalable remedy for HIV exists, for that reason, requiring people living with HIV (PLWH) to preserve long-term therapy on suppressive ART. Although successful viral suppression strategieswith ART have dramatically decreased the threat of PLWH developing AIDS-defining situations; even a quick, two-w
