Research

Renata Salatini and Claudia Arab Visting PhD Students from Brazil Carll Lab, Summer 2018Effects of e-cigarette aerosol (black) on cardiac conduction in mice.Carll Lab alumnus, Affan Irfan, MD, PhDExposure to airborne toxins is tied to arrhythmia, cardiac arrest, and heart failure in the general public. Our team seeks to validate and better understand these associations. We investigate how inhaled toxins impair cardiac conduction and contraction in both rodents and humans, with particular interest in the nervous system’s role. We study the impacts of multiple toxins, including e-cigarette aerosols, volatile organic compounds, and particulate matter from many sources (automobiles, urban atmospheres, and consumer products).

Current Investigative Questions

In both rodents and humans, the Carll lab investigates; 

  1. What are the neural and cellular pathways underlying pollutant-induced myocardial dysfunction and remodeling?
  2. How do e-cigarette aerosols adversely affect cardiac function, intracellular signaling, and neuroregulation? 
  3. How do constituents contribute to the cardiac risks of exposure to e-cigarette aerosols?

Findings

Our recent findings suggest that tobacco product aerosols alter cardiac conduction and promote arrhythmia in both mice and humans through autonomic, neural, and endocrine pathways.
