Requirements for CD8 T-cell migration into the human arterial wall.

Atherosclerotic lesions develop in the arterial intima. Among the leukocytes that accumulate in advanced atherosclerotic plaques, CD8 T cells play a quantitatively important role. They may be involved in disease progression and plaque destabilization, leading to plaque rupture or erosion.

Association of polymorphisms of the transforming growth factor-beta1 gene with the rate of progression of HCV-induced liver fibrosis.

Background: The objective of the present study was to elucidate possible relationships between four polymorphisms of the TGF-beta1 gene (-800G>A; -509C>T; Leu10Pro; Arg25Pro) and stage, histological activity grade and progression rate of liver fibrosis, classified according to the METAVIR-score.

Methods: Three study groups, i.e.
