Abstract:
Heavily treatment-experienced (HTE) individuals carry a high inflammatory burden, which is potentially increased in those with vertical HIV transmission (VT), due to lifelong viral exposure. We assessed inflammation and T-cell activation/exhaustion/senescence in HTE with VT or horizontal transmission (HT). Interleukin-6 (IL-6) was lower in VT and positively correlated with age. T-cell dysfunction was greater in HTE than people without HIV (PWOH), mainly driven by viremic VT and HT. Age and viral replication, rather than transmission mode, underlie immune dysregulation in HTE.

Immune Response Against Viral Pathogens
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
