Summary

Immunologists have long thought that certain populations of intraepithelial T lymphocytes (IELs) are born and raised in the gut mucosa. A new twist on the origin of IELs is provided by Guy-Grand and Vassalli in their Perspective, which discusses new work (Eberl and Littman) identifying the thymus as the birthplace of IELs.
