The presence of scattered tumor cells at the invading front of several carcinomas has clinical significance. These cells differ in their protein expression from cells in central tumor regions as recently shown for the EGF-TM7 receptor CD97. To understand the impact of such heterogeneity on tumor invasion, we investigated tumor cells with modified CD97(More)
We recently located a rare cytokeratin-positive (CK+) type of microvascular endothelial cell (MVEC) in the corpus luteum and aorta. Bovine corpus luteum MVEC are known to be involved in the cyclic accumulation of eosinophils and macrophages. Since leukocyte migration is specifically mediated by adhesion molecules and the release of cytokines, we compared(More)
CD97, an epidermal growth factor (EGF)-TM7 receptor, is not restricted to hematopoetic and carcinoma cells but is also found on smooth muscle cells (SMC). We have examined its location and biochemical structure in various normal and tumorigenic SMC-containing tissues. SMC of the urinary bladder, lung bronchi and bronchioles, myometrium, and gastrointestinal(More)
Leukocyte recruitment in response to inflammatory signals is governed, in part, by binding to Thy-1 (CD90) on activated endothelial cells (EC). In this study, we characterized the adhesion G-protein coupled receptor CD97, present on peripheral myeloid cells, as a novel interacting partner for Thy-1. CD97 was upregulated on polymorphonuclear cells (PMNC) of(More)
The adhesion G-protein-coupled receptor CD97 is present in normal colonic enterocytes but overexpressed in colorectal carcinoma. To investigate the function of CD97 in colorectal carcinogenesis, transgenic Tg(villin-CD97) mice overexpressing CD97 in enterocytes were generated and subjected to azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced(More)
The mechanisms by which T cells accumulate in the thyroid and support the autoimmune process in patients with Graves' disease (GD) are poorly understood. Chemokines and their receptors may be involved in this process. We have analysed the expression of CXCR3 and CCR5 as Th1-specific chemokine receptors, CCR3 as a marker for Th2 cells, CXCR4 (expressed on(More)
Thyroid glands affected by Graves' disease (GD) show striking lymphocytic infiltration, mainly by CD45RO(+) T cells. The mechanisms by which the various lymphocytic subsets are recruited and maintained in the thyroid are unknown. RANTES (regulated on activation, normal T cells expressed and secreted) in interaction with its receptors (CCR1, CCR3, CCR4 and(More)
OBJECTIVE Graves' disease (GD) and Hashimoto's thyroiditis (HT) are characterized by lymphocytic infiltrates partly resembling secondary lymphoid follicles in the thyroid. CXCR5 and its ligand CXCL13 regulate compartmentalization of B- and T-cells in secondary lymphoid organs. The aim of the study was to elucidate the role of this chemokine receptor-ligand(More)
An investigation into the use of blood chemistry variables in the identification of young adult alcoholics revealed that a combinative process utilizing 11 blood chemistry variables was superior to the use of individual measures. The investigation further validated the use of a linear discriminant analysis technique in identifying the blood chemistry(More)
Postnatal enlargement of the mammalian intestine comprises cylindrical and luminal growth, associated with crypt fission and crypt/villus hyperplasia, respectively, which subsequently predominate before and after weaning. The bipartite adhesion G protein-coupled receptor CD97 shows an expression gradient along the crypt-villus axis in the normal human(More)
