A woman aged 48 years was found to be suffering from intravascular endothelioma. The initial clinical presentation was the presence of red, painless swellings in the skin of the lower limbs. The other clinical features, and the histological changes in skin biopsies, are described and compared with those in the two previously reported patients. It is suggested that the condition is analogous to ...
Wagner’ in Germany in 1870 was the first to describe a tumor with the characteristics of a pleural mesothelioma and to recognize it as a pathological entity. He called it “a tubercle-like lymph adenoma.” From the time of this first description there has been a controversy among medical authorities until recently relative to the origin, histology and nomenclature of this dIsease. It has been var...
Endothelial intercellular adhesion molecule 1 (ICAM-1) and ICAM-2 are both involved in lymphocyte extravasation during immunosurveillance and inflammation. To define their exact role during T-cell extravasation, we used mouse T cells and ICAM-1-/-ICAM-2-/- brain endothelioma cells. ICAM-1-/-ICAM-2-/- brain endothelioma cells did not support transendothelial migration (TEM) of T cells in vitro. ...
Endothelioma cell lines transformed by polyoma virus middle T antigen (mTa) cause cavernous hemangiomas in syngeneic mice by recruitment of host cells. The production of nitric oxide (NO), as measured by nitrite and citrulline production, was significantly higher in mTa-transformed endothelial cells in comparison with nontransformed control cells. The maximal activity of NO synthase (NOS) was a...
We have distinguished five TNF-alpha-inducible cell adhesion mechanisms on microvasculature-derived endothelioma cells of the mouse which mediate the binding of different types of leukocytes. Three of these mechanisms could be identified as the mouse homologs of ICAM-1, VCAM-1, and E-selectin, of which the latter was defined by the novel mAb 21KC10. The fourth TNF-alpha-inducible cell adhesion ...
