Tumanov, Alexei V., M.D., Ph.D.
Dr. Alexei Tumanov’s research focuses on the regulation of mucosal immunity and cancer. We investigate how the immune system regulates the delicate balance between protective immunity and immunopathology at mucosal surfaces, particularly in the gut. The goal of Dr. Tumanov`s research program is to combine molecular data with in vivo models to understand the mechanisms underlying homeostatic and pathological conditions for the development of effective immunotherapies.
Dr. Tumanov graduated from Russian State Medical University, Moscow, Russia. He did his PhD work in the laboratory of Dr. Sergei Nedospasov at the Engelhardt Institute of Molecular Biology, Moscow, in collaboration with several laboratories in Europe and US, including NCI-Frederick (NIH), the Jackson Laboratory (Dr. Chervonsky`s lab), Institute of Experimental Immunology, Zurich (Dr. Zinkernagel`s lab). In 2004, Alexei joined laboratory of Dr. Yang-Xin Fu at the University of Chicago, Department of Pathology for postdoctoral training. In 2011, Alexei started his research lab at Trudeau Institute, NY. Dr. Tumanov was recruited to the Department of Microbiology, Immunology, and Molecular Genetics as an Associate Professor in Fall 2016.

We are interested in the regulation of mucosal immunity and cancer. Our main research is centered on understanding the biology of lymphotoxin (LT), member of tumor necrosis factor superfamily of cytokines. Although LT and its receptor, LTβR are known as key regulators of lymphoid organ development and maintenance, recent studies revealed the critical role of LT in protection against several mucosal pathogens and in regulation of intestinal inflammation. To understand the role of LT signaling in disease, we generated various mouse strains with genetically modified components of LT pathway. Specific ongoing projects include:
1) Understanding the role of lymphotoxin (LT) in inflammatory bowel disease and colorectal cancer.
Our recent studies reveal the critical role of LT in the regulation of innate lymphoid cells (ILCs) in the gut. ILCs are heterogeneous cell population which play key roles in the regulation of inflammation and immunity at mucosal surfaces, particularly in gastrointestinal tract. Despite recent advances in dissecting the roles of different ILC populations in intestinal homeostasis, the cellular and molecular mechanisms of protective versus pathogenic responses mediated by distinct populations of ILCs in inflammatory bowel disease (IBD) remain poorly understood, which limits the development of novel therapies. The goal of this project is to elucidate how LTβR signaling regulates intestinal inflammation in IBD and colitis-associated cancer, the major fatal complication for patients with IBD. We are also developing nanomaterial-based therapeutic approaches in intestinal injury.
2) Investigating the role of innate lymphoid cells in Campylobacter-induced colitis.
Campylobacter jejuni is a common human enteric pathogen that causes acute enterocolitis and increases the risk of developing long-term intestinal dysfunction. Our data suggest that innate immune mechanisms contribute to intestinal pathology in C. jejuni-induced colitis. We investigate how distinct populations of ILCs regulate intestinal inflammation in C. jejuni-induced colitis.
3) Immune control of chronic pain.
Chronic pain is a significant health problem that has led to an epidemic of opioid analgesic overuse and overdose. Persistent inflammation is associated with chronic pain, however the cellular and molecular mechanisms remain poorly understood. The goal of this project is to define immune mechanisms controlling inflammatory- and chemotherapy-induced neuropathic pain.
4) Tumor immunotherapy.
Novel immunotherapies for cancer are having major clinical impact. However, accompanying immune-mediated adverse reactions, such as liver toxicity, remain the major obstacle of these therapies. The goal of this project is to improve effectiveness of cancer therapy by targeting LTβR pathway in the liver.
