Rafael B Polidoro, Ph.D, is an Assistant Research Professor of Pediatrics infectious diseases at the Indiana University School of Medicine in the Ryan White Center for Pediatric Infectious Diseases and Global Health. He completed his Bachelor, Masters and PhD from Universidade Federal de Minas Gerais, Brazil, studying live-attenuated viral vector vaccines against T. cruzi and T. gondii, and one visiting PhD year at Harvard School of Public Health. He has done postdoctoral training on the role of gamma-9 delta-2 T cells in recognizing and killing Plasmodium falciparum infected red blood cells at Harvard Medical School/Boston Children’s Hospital; using CRISPR-Cas9 in primary human NK and CD4 T cells to study the roles of APOBEC and stress granules in innate lymphocytes at Harvard Medical School/Brigham and Women’s hospital; and in the role of gut microbiome on the impairment of systemic immunity against Plasmodium yoelii in mouse model.
Dr. Polidoro is interested in how the gut microbiome modulates the local and systemic immunology during infections. Particularly, how shifts in gut microbiome homeostasis can result in “immunological distraction” and its impacts in how the systemic immunity is then mounted. This work can have important consequences regarding vaccination, treatments, and major understanding of different immune responses in similar settings, where the major variable might be the gut microbiome.
