Dr. Manish Sagar is a Professor of Medicine at the Chobanian and Avedisian School of Medicine. My laboratory is primarily interested in human immunodeficiency virus type 1 (HIV-1) mucosal HIV-1 transmission and antibodies. One of our focus is to understand the biological mechanisms for the selection observed during HIV-1 transmission. Even though chronically infected subjects harbor extensive variants during transmission, only a limited number of viruses are acquired by newly infected partners. Genotypic examination of viruses present in the newly infected subject compared to those circulating in the transmitting partner suggests that the observed genetic bottleneck during transmission is not due to random chance. Laboratory studies explore the hypothesis that during transmission there is selection of specific variants with properties that confer fitness for transmission.

Another focus in the lab is to decipher correlate of immune protection. Even though infants are exposed to infected breast milk, only a small proportion (around 30%) acquire HIV-1 from their infected mother in the absence of antiretroviral protection. We hypothesize that maternally acquired antibodies present in the infant prevent HIV-1 acquisition either through neutralization or antibody dependent cellular cytotoxicity against the variants circulating in the maternal breast milk. Defining the immune correlate of protection will have important implications for HIV-1 vaccine design. Our work focuses on understanding HIV-1 envelope and host antibody evolution and impact on disease pathogenesis.

Dr. Sagar has served on numerous committees including NIH study sections and Doris Duke Charitable Foundation Early Career Development Award Review Committee. He is an active member of the Infectious Diseases Society of America (IDSA).

Diversity, Equity, Inclusion and Accessibility

As an immigrant from India, I am acutely aware of the challenges encountered by foreign born students, physicians, and researchers. My experiences as a minority, albeit not one characterized or labeled as underrepresented minority in medicine, has raised my awareness for increasing diversity in medicine and science. To that end, I have actively promoted the training and careers of those underrepresented, such as women and minorities. I have consistently mentored foreign students and physicians in my laboratory and medical practice. I have also had number underrepresented minorities who have completed their PhD and other research training in my laboratory. I will continue to promote diversity and inclusion in scientific and medical education.
My childhood in India along with my education in the United States has heightened my awareness of the inequities in medicine. I have trained in and provided care to communities that house some of the most socio-economically disadvantaged populations in the United States. I pursued a career in Infectious Disease and specialization in HIV because of infectious diseases and HIV, specifically, overwhelmingly impact minority populations with limited economic and social means. Over my career and to this day, I am committed to providing medical care and conduct research that will help alleviate these structural inequities.
