The REPRIEVE Trial recently reported high rates of sudden cardiac death (SCD) middle-aged people living with HIV-1 infection (PWH) using the WHO/NIH-recommended two nucleoside reverse transcriptase inhibitors (NRTIs)/one integrase strand inhibitor (INSTI) regimen to manage HIV-1 viremia. To date, clinically relevant animal models to delineate underlying causes for this remain limited. Here, we assessed if HIV-1-infected NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ humanized mice (Hu-mice) treated with the WHO/NIH-recommended antiretroviral regimen, dolutegravir (DTG, INSTI)/tenofovir disoproxil fumarate (TDF, NRTIs)/emtricitabine (FTC, NRTIs), can recapitulate abnormalities in the ECG and subclinical structural heart disease that serve as harbingers of SCD in middle-aged PWH. …

Individuals with rheumatoid arthritis (RA) experience increased risk of heart failure. Malondialdehyde-acetaldehyde (MAA) adducts are overexpressed and co-localize with citrullinated (CIT) proteins in RA myocardium. This study investigated whether reactive aldehyde species (RASP) inhibitors prevent MAA formation in vitro and attenuate cardiac dysfunction in a collagen-induced arthritis (CIA) mouse model. Among eight RASP inhibitors screened, ADX-246 demonstrated the greatest inhibition of MAA formation in vitro. Mice with early CIA (week 5) exhibited elevated levels of myocardial MAA adducts, myocardial inflammation, and reduced ejection fraction, but normal cardiac collagen deposition and diastolic function vs. control. By weeks 10-12, mice with chronic …

Early-onset heart failure is a major treat to healthy aging individuals with HIV-1 infection. Women with HIV-1 infection (WLWH) are especially vulnerable and develop heart failure with preserved ejection fraction (HFpEF), of which left ventricular diastolic dysfunction, vascular deficits, myocardial infarction, and fibrosis are major components. HIV-infected rodent models that exhibit these pathophysiological features remain under-reported, and this has left a void in our understanding of their molecular causes and therapeutic strategies to blunt its development. Here, we show that female NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ humanized mice (Hu-mice) infected with HIV-1ADA and treated for 13 weeks with dolutegravir …

Q2S Enhancing Pedagogy
The project details how Comparative Animal Physiology, a two-semester upper division biology elective, is transformed to meet writing-intensive discipline-appropriate criteria. Targeted and scaffolded assignments allow students to write about physiology in a variety of styles, and to help revise each other’s work to better understand the iterative process of writing. Assignments are aligned with WI student learning outcomes, to promote critical, reflective and effective communication skills.
