The experiments presented here assess the contribution of T cells to NK cell regulation and transforming growth factor-beta TGF-beta production. T cell-deficient mice exhibited high NK cell activity for longer periods of time post-infection. To determine whether the reduction in NK cell activation at later times post-infection of normal mice resulted from induction of negative regulatory elements, mice were treated with the chemical IFN and NK cell inducing agent polyinosinic-polycytidylic acid poly I:C.

In vivo expression of TGF-beta protein in normal and T cell-deficient mice was evaluated by immunohistochemical studies on splenic sections. TGF-beta proteins were not detected in sections from uninfected mice but were induced in all strains during infection.

High levels of TGF-beta proteins were localized to discrete cells, and diffuse staining was observed along marginal zones. The ability of the splenic leukocytes to release TGF-beta into conditioned media was evaluated in the Mv 1 Lu biologic assay. Transient acid treatment to release active factor from the latent form and use of specific neutralizing antibodies demonstrated that leukocytes from all strains of infected mice had released latent TGF-beta 1 into conditioned media.

Treatment with active TGF-beta 1 reduced the s of NK cells per spleen in infected nude mice to the levels found in infected littermate controls.
