MSK Study Is the First to Link Microbiota to Dynamics of the Human Immune System

MSK researchers have shown for the first time that the concentration of different types of immune cells in the blood changes in relation to the presence of different bacterial strains in the gut.

At Work: Computational Biologist Joao Xavier

Computational biologist Joao Xavier combines computer models and laboratory experimentation to understand how cells interact.

Turning to Bacteria for Clues

Several Memorial Sloan Kettering investigators are focused on the study of bacteria, which can teach us much about human health, and about cancer in particular.

Disclosures

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.

MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.

Joao Xavier discloses the following relationships and financial interests:
