abstract：:Mediators of lymphocyte infiltration in inflammatory thyroid disease have yet to be identified. Here we examine the ability of IL-1beta to enhance the production of chemoattractants by human thyrocytes. Primary cultures, when treated with the cytokine, release T lymphocyte chemotactic activity.
