Wanjalla MD, PhD
Assistant Professor of Medicine

Dr. Celestine (Celly) Wanjalla is a physician scientist in the Division of Infectious Diseases. She earned her undergraduate degree in Biological Sciences with a distinction in research from Cornell University in Ithaca, and her MD PhD in Immunology and Microbial pathogenesis at Thomas Jefferson University in Philadelphia. She was awarded the Jefferson Graduate School Award in Translational Medicine. She completed residency and fellowship training in Internal Medicine and Infectious Diseases at VUMC. She was awarded a Vanderbilt Scholars in HIV and Heart, Lung, Blood and Sleep Research (V-SCHoLARS) K12 award during her postdoctoral training with Dr. John Koethe studying Adipose Tissue T cells and endothelial cell dysfunction in people living with HIV. Her current research seeks to comprehensively define the role of virus-specific immune cells in the pathogenesis of atherosclerotic cardiovascular disease and other diseases of aging. When she is not in the laboratory, she enjoys hiking with her family, trying out new recipes and traveling.

Cardiovascular disease remains the leading cause of death globally despite advancements in the detection and mitigation of risk factors. Though inherently multifactorial, chronic immune activation and inflammation are key mediators of atherosclerotic cardiovascular disease and other comorbidities. Persons living with HIV have twice the risk of developing cardiovascular disease. Persistent exposure to HIV antigens and co-infection with chronic herpes viruses such as CMV or hepatitis B/C contribute to chronic inflammation in PWH and appear to be important in cardiovascular disease pathogenesis.

My lab has adopted a multidisciplinary approach to i) Define virus-specific innate and adaptive immune cells in the peripheral blood and coronary arteries of persons with cardiometabolic disease using existing multiparameter flow cytometry and single-cell techniques. ii) Optimize techniques to better understand the antigenic drivers of the adaptive immune response at the tissue level. Specifically, we design studies that link the viral reservoirs, virus-specific memory T cells, and epitope discovery. iii) Apply/Implement changes in cardiovascular disease risk assessment and therapeutic approaches to improve outcomes in patients.

Major research questions:

  • What is the role of chronic herpes and other viral infections in the pathogenesis of CVD? Do viral antigens expressed in coronary plaques contribute to residual cardiovascular risk?

  • Is there synergy between viral antigens and lipids in the stimulation of adaptive immune cells within coronary plaque? Does this modify the viral epitopes?

  • Can we reduce the burden of residual CVD risk and improve clinical outcomes by targeting viral reservoirs and/or anti-viral cells of the immune system?

Virus-specific immune responses, chronic inflammation and aging

Monkeypox – what do we know about the virus, and how can we treat the disease?

Monkeypox – what do we know about the virus, and how can we treat the disease? The monkeypox virus has been studied, and its mechanism of replicating and invading human cells are understood. Due to prior research on orthopoxviruses, there is a test currently available for diagnosing monkeypox. Additionally, antiviral therapies are currently under investigation. Finally, a monkeypox vaccine is approved and available for individuals at high risk for contracting the virus. While monkeypox treatment options continue to be studied, a variety of medical resources currently exist for high-risk individuals as well as those who were recently exposed to monkeypox.

Our research focuses on how obesity and aging reshape immune responses and lead to inflammatory diseases. Immune cells are sensitive to their metabolic environment, which affects intracellular metabolism and signaling and fine-tune immune functions. We are interested in understanding how metabolic cues regulate communication between immune cells, focusing on dendritic cells and T cells. Our Lab studies how obesity and aging disturb the immune and metabolic balance and lead to excessive inflammation, including diseases such as psoriasis and asthma. We decode molecular mechanisms that link dendritic cell metabolism to tissue inflammation by combining mouse models of inflammatory skin and lung diseases with systems immunology approaches.

Monkeypox – symptoms, transmission, and prevention

Monkeypox – symptoms, transmission, and prevention. Since the 1970s, there has been a steady rise in monkeypox virus cases. While the Orthopoxvirus genus is no stranger to the United States, the specific virus responsible for the monkeypox outbreak has largely been found in African countries, until recently. The geographic footprint of the virus and age of those contracting the disease has steadily expanded. While the epidemiology and symptoms associated with monkeypox are complex, the Centers for Disease Control (CDC) and World Health Organization (WHO) have multiple resources to educate us on the disease progression and modes of transmission.
