Hepatic sinusoidal endothelial cells can store and metabolize serum immunoglobulin
Shinichi Iwamura, Hideaki Enzan, Toshiji Saibara, Saburo Onishi, Yasutake Yamamoto – 1 November 1995 – Sinusoidal inclusion‐containing endothelial cells in the liver were investigated with particular interest in their capacity of metabolizing immunoglobulin. Formalin‐fixed deparaffinized liver specimens were used for immunohistochemistry, and pronase digestion was proved to be effective for antigen retrieval of immunoglobulin. The inclusions in sinusoidal endothelial cells were strongly immunostained with anti‐immunoglobulin (Ig)G, IgA, and IgM antibodies in predigested sections.
