HIV persists in late coronary atheroma and is associated with increased local inflammation and disease progression.

Chronic inflammation contributes to the prevalence of cardiovascular disease in people living with HIV (PLWH). The immune mechanisms driving atherosclerosis progression in PLWH remain unclear. This study conducted comprehensive assessments of medium-sized coronary arteries and aorta from deceased PLWH and controls without HIV using DNA/RNA assays, spatial transcriptomics, and high-resolution mass spectrometry.

Cytokine and chemokine receptor profiles in adipose tissue vasculature unravel endothelial cell responses in HIV.

Chronic systemic inflammation significantly increases myocardial infarction risk in people living with HIV (PLWH). Endothelial cell dysfunction disrupts vascular homeostasis regulation, increasing the risk of vasoconstriction, inflammation, and thrombosis, contributing to cardiovascular disease. We aimed to characterize endothelial cell (EC) chemokines, cytokine, and chemokine receptors of PLWH, hypothesizing that in our cohort, glucose intolerance contributes to their differential expression implicated in endothelial dysfunction.

Inflammation in HIV and Its Impact on Atherosclerotic Cardiovascular Disease.

People living with HIV have a 1.5- to 2-fold increased risk of developing cardiovascular disease. Despite treatment with highly effective antiretroviral therapy, people living with HIV have chronic inflammation that makes them susceptible to multiple comorbidities.

Cytokine and Chemokine Receptor Profiles in Adipose Tissue Vasculature Unravel Endothelial Cell Responses in HIV.

Chronic systemic inflammation contributes to a substantially elevated risk of myocardial infarction in people living with HIV (PLWH). Endothelial cell dysfunction disrupts vascular homeostasis regulation, increasing the risk of vasoconstriction, inflammation, and thrombosis that contribute to cardiovascular disease. Our objective was to study the effects of plasma from PLWH on endothelial cell (EC) function, with the hypothesis that cytokines and chemokines are major drivers of EC activation.
