Program for Immunophysiology and Disease

Revealing mechanisms of immune control and disease pathogenesis to prepare for, and protect against, future global health threats

Our Focus

The Program for Immunophysiology and Disease is dedicated to understanding the immune system’s role in both normal physiology and disease pathogenesis. This knowledge is crucial for preparing for and protecting against current and emerging global health threats.

This program explores how the immune system maintains balance in the body, studying the physical and chemical conditions that must be preserved for optimal health. Researchers also investigate how the immune system recognizes and responds to specific threats, effectively neutralizing pathogens or harmful agents that can cause illness.

In addition, the program addresses situations where the immune system’s responses go awry, either failing to eliminate threats or causing damage to healthy tissues. These dysfunctions can create new health challenges, and understanding them is crucial for developing treatments that restore proper immune function.

These researchers also study the immune system’s role in maintaining normal health. It investigates scenarios where immune function may be compromised and how this impacts overall physiology. Through these efforts, the Program for Immunophysiology and Disease aims to reveal critical insights that will inform the development of targeted therapies and interventions, contributing to global health security.

Our Initiatives

Homeostasis

The Homeostasis initiative focuses on understanding the steady-state conditions that a living system maintains to ensure optimal function. By exploring the physical and chemical balance that the immune system preserves, researchers aim to uncover how disruptions to this balance can lead to disease. This research provides valuable insights into maintaining health and preventing immune dysfunction that can arise from environmental or internal factors.

Productive

The Productive initiative examines how the immune system responds effectively to specific threats, such as pathogens. This research aims to identify the immune mechanisms that function properly to detect, target, and eliminate infectious agents or harmful stimuli like cancer cells. By studying these successful responses, researchers can develop strategies to enhance immune function in individuals whose systems fail to respond adequately.

Destructive

The Destructive initiative investigates how immune responses become harmful or ineffective, shifting from defense to dysfunction. This includes conditions where the immune system not only fails to clear pathogens but also turns its defenses against the body’s own tissues—a hallmark of autoimmune diseases. By examining these maladaptive patterns, researchers seek to understand the mechanisms that drive self-inflicted damage and chronic inflammation. Unraveling how healthy immune regulation breaks down, and learning how to restore it, is key to preventing these destructive cycles and developing interventions that preserve health instead of endangering it.

Kwon Lab Study Links Gut Immune Cell Metabolism to Barrier Damage in HIV

Sep 11, 2025 Features

A new study led by investigators at the Kwon Lab and collaborators shows how energy use by gut immune cells can weaken the intestinal lining in people living with HIV, even when the virus is controlled by treatment. The work identifies a metabolic switch inside these cells as a promising target to help protect the […]
