1. Structural changes in the thymus during the evolution experimental renal hypertension were investigated to determine their possible role in the genesis of hypertensive vascular disease. 2. The thymus, adrenal glands and the progression of hypertensive vascular lesions were investigated in rats during the first 30 days after occlusion of the aorta between the two renal arteries. 3. Hypertensi...

Spleen cells from mice treated with cyclophosphamide (100 to 200 mg/kg) were unable to generate effective cytotoxic thymus-denived cells to allogeneic tumor cells in vitro. The inability of lymphoid cells from cyclophosphamide-treated mice to generate thymus-denived cytotoxic cells became more ap parent as the number of responding cells became limited. This depressed response was not due to the...

We have examined whether the thymus can produce immature T cell precursors for subsequent positive selection in the periphery. Using the intestine as a model system, we demonstrate that extrathymic MHC class I molecules positively select thymus-derived TCR-alpha beta CD8+ intestinal intraepithelial lymphocytes. Grafting of MHC class I+ thymus onto MHC class I- hosts resulted in the generation o...

Lectin agglutination and cell surface galactosyltransferase (EC 2.4.1.67; 1-O-alpha-D-galactosyl-myo-inositol:raffinose galactosyltransferase) enzyme activity have been studied with thymus and spleen lymphocytes of neonatal rats. Thymus lymphocytes were more agglutinable by concanavalin A than by wheat germ agglutinin, whereas spleen lymphocytes were more agglutinable by wheat germ agglutinin t...

Chemokines regulate leukocytes trafficking in normal and inflammation conditions. Thymus-seeding progenitors are made in bone marrow and migrate to the thymus where they undergo their maturation to antigen-specific T cells. Immature T cells are in thymic cortex, while mature thymocytes are in medulla. Chemokines may be important for homing of thymus-seeding progenitors, and/or differential thym...

The in vitro secondary cytotoxic T lymphocyte (CTL) response to Sendai virus-treated stimulator cells by primed spleen cells from thymus gland-grafted nude mice was examined. BALB/c (H-2d) nude mice grafted with allogeneic C57BL/10 (H-2b) thymus glands developed CTL responses directed exclusively to Sendai virus-infected H-2d target cells. (C57BL/6 X BALB/c)F1 nude mice grafted with thymus glan...
