Immune Priming Unit
Oyebola Oyesola, DVM, Ph.D. (She/Her/Hers)
NIH Independent Research Scholar
The Immune Priming Unit is focused on understanding how previous infection and exposure to environmental antigens can reprogram the immune system to influence outcomes to subsequent insults and injury.
Helminths infections are widespread and affect over a billion people worldwide. These worms have co-evolved with their vertebrate host for hundreds of millions of years before recent regional efforts aimed at eradication. Some of these worms can migrate through different tissue sites, such as the lungs, to induce a Type 2 inflammatory and regulatory response. This response can persist even after worm clearance and may influence responses to subsequent immunological challenges.
Furthermore, humans are constantly exposed to various antigens and microbes in their immediate environment. These microbes can play important roles in shaping immune response and contributing to immune variation within a population. However, use of mice in specific pathogen free (SPF) facilities has not favored an understanding of the contribution of an individual environmental history in responses to subsequent insults.
Our unit is focused on understanding how helminth infection and exposure to environmental antigens can reprogram the immune system to influence outcomes to other insults. To answer this question, we use various murine models, infection models, environmental models, multicolor flow cytometry and other single cell approaches to dissect the contributions of reprogrammed innate cells to the development of host resistance and/or susceptibility to other insults.
Ph.D. Immunology and Infectious Disease, Cornell University
M.Sc. Infection and Immunity, University of Leicester
DVM Doctor of Veterinary Medicine, University of Ibadan
Dr. Oyesola obtained her Veterinary Degree (DVM) from the University of Ibadan, Nigeria graduating with several distinctions at the end of her study at Ibadan. Motivated by her interest to better understand diseases of global and zoonotic importance, Dr. Oyesola pursued a postgraduate MSc. training in Infection and Immunity at the University of Leicester as a Commonwealth Shared Scholar. Following this, as a recipient of the Cornell African Scholar and Graduate Research Award, she obtained her Ph.D in Immunology and Infectious Disease at the Cornell University College of Veterinary Medicine. Her dissertation work in the Tait-Wojno lab focused on dissecting the role of prostaglandin D2 in the regulation of mucosal responses during Type 2 inflammation.
In 2020, Dr Oyesola moved to the NIH where she became a visiting post-doctoral fellow in the Loke lab at the Laboratory of Parasitic Diseases, NIAID, NIH. Her work here was focused on understanding how an individual’s macro and/or microenvironment together with its interaction with host genetic factors can influence their susceptibility to disease, disease pathogenesis, and outcomes.
In 2023, Dr. Oyesola received an Independent Research Scholar Award from NIH, allowing her to continue her study on how an individuals’ environmental and/or infection history alter the immune system and influence their response to subsequent infections.
Dr. Oyesola is passionate about global health issues and promotion of diversity in science and engages with the community through this lens.
