The researchers deleted the HIC1 gene in certain innate lymphoid cells in the mouse intestine and found that this increased the susceptibility of the mice to infection with the bacterium Citrobacter rodentium.

Further investigation revealed that the increased susceptibility was due to a reduction in production by the innate lymphoid cells of IL - 22, a protein that plays a key role in the intestinal immune response.

Gregory F. Sonnenberg, PhD, research associate in the Department of Medicine, Gastroenterology Division, and the Institute for Immunology at the Perelman School of Medicine, University of Pennsylvania, with postdoctoral researcher Matthew Hepworth, PhD, report in Nature that innate lymphoid cells (ILCs) directly limit the response by inflammatory T cells to commensal bacteria in the gut of mice.

Innate lymphoid cells (ILCs) are immune cells that regulate early immune responses against viruses, bacteria and parasites through the release of soluble factors.
