Like other immune cells, most Tregs reside in the body's lymph nodes, but some live permanently in other tissues, where they seem to have evolved to assist with local metabolic functions as well as playing their normal anti-inflammatory role.

Their research seeks to investigate how these T cells, called natural killer T cells (NKT), survive, grow, and regulate other immune cell types.

In a typical immune response, for instance, inflammatory proteins called cytokines will be released by immune cells at a site of inflammation and then other immune cells will use these cytokines like a trail of breadcrumbs to home in on the site of infection and destroy the pathogens that are causing it.

Still other immune cells just eat the invaders whole.

T cells detect cellular abnormalities, directly destroy bacterially infected cells, and support other immune cells to produce antibodies.

The release of inflammatory cytokines, or intercellular signaling molecules such as interleukin - 1 (IL - 1), interleukin - 2 (IL - 6), and tumor necrosis factor alpha (TNF - α) at the site of immune activation causes other immune cells migrating throughout the lymphatic vessels of the body to express more cell adhesion molecules (CAMs).
