Professional Background

Dr. Dhillon received the PhD degree in 2003 from the Postgraduate Institute of Medical Education and Research in Chandigarh, India and then moved to the University of Kansas Medical Center for a postdoctoral fellowship, where she has risen to the rank of tenured Professor of Medicine. She also has a joint appointment in the Department of Molecular and Integrative Physiology. Dr. Dhillon is an international leader in studying disorders of the pulmonary circulation, including the cellular and molecular pathogenesis pulmonary hypertension in the setting of HIV-infection, and illicit drug use. As a Director of Pulmonary Research, she is actively involved in promoting the research careers of junior faculty members of the division.

Dr. Dhillon is also a Director of the Parker B Francis (PBF) Summer Fellowship Program that provides opportunities to undergraduate students, particularly those from underrepresented minorities in science and medicine for hands-on innovative research experience.

Research

Overview

Research in Dr. Dhillon laboratory is focused on understanding the pathogenesis of HIV-associated end stage diseases particularly cardio-pulmonary disorders. One of the primary research efforts is aimed at understanding how HIV-1 and drugs of abuse contribute alone and in concert to the vascular dysfunction associated with pulmonary hypertension and other cardiovascular/pulmonary complications. The other main focus of the laboratory is aimed at understanding the interplay of macrophages, T cells, cytokines and chemokines in lung pathology associated with HIV-infection. We demonstrated important role of extracellular vesicles (EVs) mediated cell-cell communication in HIV-related chronic lung diseases. Recently we began to question the relationship of alterations in the circulating EVs with the severity of illness in patients infected with SARS-CoV-2.

Current research is aimed at:
-Elucidating the role of long non-coding RNAs in the regulation of proliferative and anti-proliferative cascades in pulmonary smooth muscle cells.
-Investigating the role of inflammatory cell-derived extracellular vesicles in pulmonary vascular remodeling.
-Defining the mediators and markers of endothelial injury and disease severity in COVID-19 patients and how these changes may persist in individuals with long term complications
