Research Description
Our bodies are constantly exposed to infectious agents wanting to invade and proliferate within us. One of the areas with high exposure to foreign antigens is the mucosa of the digestive tract. The mucosal immune system protects the intestines from pathogenic invaders and at the same time discriminates those organisms that are important for our overall homeostasis. My research focuses on the role of intestinal intraepithelial lymphocytes, IEL (a group of immune cells present in the intestinal epithelium) during immune responses in the mucosa.
Our current research involves a novel IEL population discovered in our lab known as innate CD8alpha-alpha cells (or iCD8alpha). We have shown that this population of cells is important for controlling the colonization of pathogenic bacteria, such as Citrobacter rodentium. We believe that one of the roles of these cells is to provide survival signals to other IEL via the cytokine osteopontin. Moreover, we have also observed that iCD8alpha cells mediate mucosal immune responses through secreted granzymes.
These are exciting areas of research that once better understood will provide evidence of how mucosal immune responses occur in the intestinal epithelium, and will provide foundations for therapeutic interventions of gastrointestinal diseases.

Available Postdoctoral Position Details
Posted: 12/17/2020
The laboratory of Dr. Olivares-Villagómez is looking for a candidate for a 3-year postdoctoral position. This individual should or plan to have a Ph.D. degree or equivalent, preferentially with expertise on the area of molecular and/or cellular immunology. The candidate should be able to work independently, be capable of fully grasping the relevant literature on the field, formulate appropriate hypothesis and experiments, and be creative. Experience with mouse models is preferred, although not a requirement. The candidate should possess excellent English conversational and writing skills. All the members in the laboratory of Dr. Olivares-Villagómez work as a team, and we expect the candidate to have a positive attitude and be a good lab citizen.
Dr. Olivares-Villagómez investigates different aspects of mucosal immunology. One of the main projects relates to the biology of intestinal intraepithelial lymphocytes (IEL), with special emphasis on inflammatory diseases. His laboratory also studies the role of two molecules in intestinal homeostasis: osteopontin and granzyme B.
The laboratory of Dr. Olivares-Villagómez is part of the Department of Pathology, Microbiology and Immunology at Vanderbilt University Medical Center and the Vanderbilt Institute for Infection, Immunology and Inflammation. VUMC is at the vanguard of biomedical research with a vibrant scientific community and within the top 20 universities with substantial funding from the National Institutes of Health. VUMC is well equipped for biomedical research and possess state-of-the-art cores for sequencing, flow cytometry, mass spectrometry, etc.
VUMC is located in Nashville, Tennessee, an energetic city recognized for its eclectic music, friendly Southern atmosphere, high standard of living, great food and extensive green areas.
Individuals interested in this position should send their CV, brief statement of research experience/interests, and contact information for at least two references.
