Immuno-cell metabolic changes in HIV-1 infection.

Area of Science:

• Immunology
• Metabolic pathways
• Viral infections

Background:

• Immune cell metabolic reprogramming is integral to human immunodeficiency virus 1 (HIV-1) infection and immune responses.
• Metabolic shifts in immune cells occur throughout HIV-1 infection stages, from acute to chronic and latent phases, mirroring T-cell exhaustion.
• Dysregulated immune metabolism impairs immune cell function, contributing to immune dysfunction and chronic inflammation.

Purpose of the Study:

• To review the metabolic profiles and roles of key immune cells (T cells, monocytes-macrophages, dendritic cells, NK cells, B cells) during HIV-1 infection.
• To emphasize the impact of HIV-1 on the metabolic pathways of various immune cell types.
• To highlight therapeutic strategies targeting immune metabolism for HIV-1 management.

Main Methods:

• Literature review of studies on immune cell metabolism in HIV-1 infection.
• Analysis of metabolic alterations across different immune cell populations.
• Examination of metabolic pathway changes during acute, chronic, and latent HIV-1 infection.

Main Results:

• HIV-1 infection significantly alters the metabolic pathways of diverse immune cells, including T cells, monocytes-macrophages, dendritic cells, natural killer cells, and B cells.
• These metabolic dysregulations are linked to immune cell dysfunction, T-cell exhaustion, and persistent inflammation.
• Metabolic reprogramming is a critical factor in HIV-1 pathogenesis and progression.

Conclusions:

• Immune cell metabolism is a key determinant of immune responses and disease progression in HIV-1 infection.
• Targeting metabolic pathways in immune cells presents promising therapeutic avenues for inhibiting viral replication and restoring immune function.
• Further research into immune cell metabolic profiles can lead to novel strategies for controlling HIV-1 and associated chronic inflammation.
