Molecular epigenetics, chromatin, and NeuroAIDS/HIV: immunopathological implications

Area of Science:

• Molecular biology
• Immunology
• Genetics

Background:

• Epigenetics investigates environmental influences on heritable traits.
• Molecular epigenetics differentiates non-coding DNA (ncdDNA) from coding DNA (cdDNA), impacting physiology.
• Molecular cartography (genomics, proteomics, interactomics) maps gene interactions in cellular and organ function.

Purpose of the Study:

• To explore the intersection of molecular cartography, epigenetics, and chromatin assembly, repair, and remodeling (CARR) with the RNA interfering signaling complex (RISC).
• To apply these integrated research areas to understand the immuno-neuropathology of HIV-1 infection.
• To propose a novel working hypothesis for molecular immune epigenetics in HIV/AIDS.

Main Methods:

• Examining the interplay between CARR and RISC in gene expression regulation.
• Analyzing the structure-function relationship of chromatin in HIV-1 infection.
• Investigating the cdDNA/ncdDNA ratio and nucleotide variations in untranslated regions (UTRs) of mRNA.

Main Results:

• The study integrates CARR and RISC research for a new perspective on HIV-1 immuno-neuropathology.
• A novel hypothesis of molecular immune epigenetics is presented for HIV/AIDS.
• Potential consequences of chromatin structure, cdDNA/ncdDNA ratio, and UTR divergence on immune surveillance in HIV/AIDS are discussed.

Conclusions:

• CARR plays a crucial role in cellular, humoral, and molecular immune epigenetics within HIV infection.
• Understanding these epigenetic mechanisms is vital for immune surveillance and health preservation in HIV/AIDS.
• This research highlights the intricate relationship between epigenetics and HIV-1 pathogenesis.
