Activated lymphocyte (liver inflammation, human)

Electron microscopy. A cytotoxic T cell (2) is localized within the sinusoid (3) in the liver (8), surrounded by erythrocytes (1) and debris. The lymphocyte with an irregular indented nucleus shows juxta-nuclearly partly swollen Golgi areas (*) and aggregation of mitochondria (4) in the cytoplasm. Few dense-stained granules (5) and pleiomorphic structures (6) are present in the vicinity of the Golgi area. At (→) close contact with irregular microvilli of a hepatocyte. (7) activated endothelial cell in the liver sinusoid. (8) part of a hepatocyte.
