Podell Lab

Dr. Podell’s laboratory studies the pathogenesis of tuberculosis (TB) to better understand the host immune response to M. tuberculosis infection, known as the granuloma. Our laboratory focuses on identifying immune correlates of protection against M. tuberculosis, the influence of acquired risk factors on the spectrum of TB disease outcomes, and the influence of metabolism on host response to infection. Through this research, we aim to identify targeted responses for vaccine candidates and new approaches to host-directed therapy for improving the prevention and treatment of TB.

Immune Mechanisms of Protection Against TB Center (IMPAc-TB)

The mechanisms of immune function that correlate with protection from M. tuberculosis infection remain elusive. This limits our ability to improve upon vaccination strategies. Using a harmonized cross-species approach, this multi-center award applies innovative computational pathology approaches to better understand vaccine-induced immunity in situ.

research project

The role of vitamin A in TB pathogenesis

Vitamin A deficiency increases the risk of progression to clinically active TB disease by up to 10-fold in human subjects. Known as the “anti-infective” vitamin, vitamin A plays a critical in immunity to infection. Our goal is to understand how a deficiency in vitamin A alters immune function in TB, and whether supplementation represents a treatment approach.

research project

Immune dysfunction in the comorbidity of diabetes and tuberculosis

The incidence of type 2 diabetes is rapidly increasing in nations where TB is endemic. Increasing the risk of TB disease progression by 3-fold, there is a critical need to understand how uncontrolled diabetes impacts TB immunity and whether diabetes management can improve the response to infect.

research project

Lipid antigens in immunity to TB

CD1 is an antigen presentation molecule exclusive to lipid antigens. Specific cell wall lipids of the organism M. tuberculosis serve as CD1-restricted antigens for T cells. The goal of this research is to understand which lipids participate in the immune response within infected tissue and whether CD1 contributes to protection from progressive TB disease.
