Research
Research Overview:
Dr. Segal and his lab studies innate immune responses to infection, injury, and the tumor microenvironment. One major interest of his lab is to study NADPH oxidase as a critical regulator of inflammation and host defense. NADPH oxidase is an emergency host defense pathway that is rapidly activated in response to certain microbial products, and converts molecular oxygen to superoxide anion and downstream reactive oxidant intermediates (ROIs).
In addition to its critical host defense role, NADPH oxidase also functions to restrain inflammation by modulating redox-sensitive innate immune pathways during infection and injury. Over the past few years, they have extended their research to understand how products of cellular necrosis and the innate immune responses they induce affect the tumor microenvironment, with a specific focus on ovarian cancer. They found that innate immune responses in the tumor microenvironment mimic those stimulated by infection and likely contribute to tumor progression.
Current Program
- Innate immune responses during infection and injury
