Dr. Alexander Poltorak's lab at Tufts University studies how the body responds to bacterial infections, specifically focusing on a protein called ZBP1. They explore how ZBP1 influences cell death and inflammation in response to lipopolysaccharides (LPS), which are components of bacterial cell membranes. Their research aims to uncover new pathways in the immune response and identify potential therapeutic targets to improve treatments for infections.

Dr. John J. Iacomini's lab at Tufts University focuses on understanding how microRNAs regulate gene expression and influence kidney transplant rejection. By studying these small RNA molecules, the lab aims to uncover the mechanisms behind chronic antibody-mediated rejection, which is a leading cause of transplant failure. Their research involves a combination of advanced techniques to map interactions between microRNAs and their target mRNAs, providing insights that could improve the success rates of kidney transplants.

Dr. Xudong Li's research lab focuses on understanding how certain cellular processes affect the function and fitness of regulatory T cells, which are essential for maintaining a healthy immune response. The lab particularly investigates the role of heme synthesis, an important biological process, in controlling these T cells' abilities to prevent autoimmune diseases. By studying the effects of a specific enzyme on Treg cells, the goal is to develop new therapies that could enhance the body's natural defenses against autoimmune disorders.
