HIV immune activation plays an important role in the immune pathogenesis of this disease. The mechanisms that drive this immune activation are partially defined and may be the result of multiple factors. Although the introduction of concomitant antiretroviral therapy (cART) has improved life expectancy in HIV-infected individuals, some sustained immune activation occurs in these patients when plasma HIV RNA levels are \\\'undetectable\\\'. There is evidence that A better understanding of immune activation pathways should be of value in developing complementary therapies to restore the immune system in HIV-infected patients. This paper describes cytokine-mediated pathways of immune activation of her CD4 and CD8 T-cell pools during HIV infection.

The management of Human Immunodeficiency Virus (HIV) necessitates a nuanced comprehension of immune responses, with the CD4/CD8 ratio emerging as a pivotal parameter in this regard. This review investigates the clinical implications of CD4/CD8 ratios in HIV, encompassing their role as prognostic markers, treatment monitoring tools, and indicators of immunological reconstitution during antiretroviral therapy. We explore the baseline CD4/CD8 ratio in healthy individuals, scrutinize its prognostic significance in HIV progression, and assess its dynamic changes throughout treatment. Additionally, the article addresses challenges, controversies, and future directions in CD4/CD8 ratio research, offering a comprehensive overview of its potential as a key immunological marker in the ongoing battle against HIV.

The immune response against human immunodeficiency virus (HIV) infection is a complex interplay between various components of the immune system, with CD8+ T-cells occupying a central role in viral control. This review critically examines the functionality of CD8+ T-cells in HIV defense, highlighting their importance in controlling viral replication, the evasion strategies employed by HIV, and the challenges encountered in harnessing CD8-mediated immunity for therapeutic purposes. We discuss the heterogeneity of CD8+ T-cell responses, the mechanisms of viral escape, and the phenomenon of CD8+ T-cell exhaustion. Additionally, recent advancements and controversies in the field are addressed, along with future perspectives on enhancing CD8-mediated immunity as a therapeutic strategy against HIV. This review aims to provide a comprehensive understanding of the complexities surrounding CD8+ T-cell functionality in HIV defense, paving the way for further research and therapeutic developments in the fight against HIV/AIDS.
