Kevin J. Tracey, a neurosurgeon and inventor, is the president and CEO of the Feinstein Institute for Medical Research, professor of neurosurgery and molecular medicine at the Zucker School of Medicine, and president of the Elmezzi Graduate School of Molecular Medicine [1] in Manhasset, New York. The Public Library of Science Magazine, PLOS Biology, recognized Tracey in 2019 as one of the most cited researchers in the world. [2]

Early life and education

Tracey was born in Fort Wayne, Indiana. He earned a Bachelor of Science (B.S.) degree in chemistry from Boston College in 1979 and a Doctor of Medicine (M.D.) degree from Boston University in 1983. From 1983 to 1992 he completed his neurosurgical training at New York Hospital-Cornell University Medical Center [3] under neurosurgeon, Russel Patterson. During his residency, he conducted research as a guest investigator at Rockefeller University. [4]

Career

In 1992, Tracey joined Northwell Health (then North Shore-LIJ Health System), [5] in Manhasset, New York, where he practiced neurosurgery and founded the Laboratory of Biomedical Science, later renamed the Tatyana and Alan Forman Family Laboratory of Biomedical Science. In 2005, he was appointed president and CEO of the Feinstein Institute for Medical Research, and president of the Elmezzi Graduate School of Molecular Medicine. [1]

He co‑founded '''SetPoint Medical''', a biotechnology company developing vagus nerve stimulation devices for autoimmune diseases, and co‑founded the '''Global Sepsis Alliance''', an international non‑profit organization for sepsis awareness and prevention. [6] [7] [8] [9]

In 2021, Tracey and colleagues at the Feinstein Institutes received a five‑year, $3.7 million grant from the National Institutes of Health to investigate the molecular mechanisms underlying bioelectronic medicine. [10]

Research and scientific contributions

Tracey’s research focuses on the interaction between the nervous and immune systems, particularly the neural regulation of inflammation.

Tumor necrosis factor and HMGB1

In early studies, Tracey and his collaborators identified '''tumor necrosis factor (TNF)''' as a key mediator of shock and tissue injury. [11] [12] They first demonstrated the anti‑inflammatory activity of monoclonal anti‑TNF antibodies, a discovery that supported the development of biologic therapies targeting TNF for rheumatoid arthritis and Crohn’s disease. [13]

In 1999, his team reported that '''high mobility group box 1 (HMGB1)'''—a nuclear DNA‑binding protein—acts as a late‑phase inflammatory mediator, explaining mechanisms of sterile inflammation following trauma and sepsis. [14]

The inflammatory reflex and vagus nerve

In the 1990s, Tracey and colleagues discovered that electrical or pharmacologic stimulation of the '''vagus nerve''' inhibits cytokine release, including TNF, through an anti‑inflammatory neural pathway. He described this mechanism as the '''inflammatory reflex''', a bidirectional feedback circuit between the nervous and immune systems. [6] [8] [15]

The Tracey lab mapped the inflammatory reflex using genetic, immunological, and bioelectronic tools to define the molecular and neuroscience mechanisms. [14] An unexpected finding from this work is the vagus nerve, a parasympathetic nerve, controls the splenic nerve, a sympathetic nerve. [16] Additionally in 2011, Tracey and colleagues discovered a memory T cell subset that secretes acetylcholine in the spleen when activated by signals arising in the vagus nerve, named "T ChAt" cells. [16] These regulatory T cells produce acetylcholine, the chemical signal to macrophages which turns off production of TNF and other inflammatory mediators. [16]

In May 2018, Tracey's team was first to decode specific signals that the nervous system uses to communicate immune status and alert the brain to inflammation. Identifying these neural signals and what they're communicating about the body's health provides insight into diagnostic and therapeutic targets, and device development. [17] In February 2019, Tracey along with a team led by Tak Mak, PhD, and Maureen Cox, PhD, reported that T ChAt regulate the development of immunity during virus infections. [18]

In November 2020, they reported that neurons in the brainstem dorsal motor nucleus (DMN) of the vagus nerve transmit signals to the celiac-superior mesenteric ganglia in the abdomen. This experiment combined optogenetics, anatomical and functional mapping, and measurement of TNF production to show for the first time that parasympathetic vagus neurons control sympathetic splenic neurons, because the parasympathetic and sympathetic nervous systems were believed to be independent. [19]

In May 2025, Kevin J. Tracey published The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes, a book exploring the role of the vagus nerve in regulating the immune system. [20] Drawing from research, Tracey discusses how stimulating the vagus nerve can turn off inflammation and could offer treatments for rheumatoid arthritis and inflammatory bowel disease, among others.
