ABSTRACT

The global burden of HIV continues to affect over 37 million individuals, disproportionately impacting populations in sub-Saharan Africa (SSA), where access to antiretroviral therapy (ART) is often limited. Chronic immune activation and inflammation remain key contributors to HIV progression, even in patients on ART. This has led to increased interest in complementary therapies, particularly the use of traditional medicinal plants with immunomodulatory properties. This paper investigates the immunological mechanisms behind HIV pathogenesis, reviews the ethnopharmacological use of medicinal plants such as Moringa oleifera, Azadirachta indica, and Momordica foetida, and evaluates their phytochemicals and immunomodulatory potential in modulating HIV-induced CD4+ T cell activation and exhaustion. Results from in vitro and community-based studies demonstrate that these plants can influence immune responses, reduce markers of T cell exhaustion (e.g., CD69, HLA-DR, PD-1), and exhibit hepatoprotective and nephroprotective effects. The study emphasizes the value of integrating ethnobotanical knowledge with modern pharmacological research to develop novel immunotherapeutic agents. However, more rigorous clinical trials and toxicity profiling are essential to validate their efficacy and safety, particularly when used alongside ART.
