Tissue localization and kinetics of pit cells or large granular lymphocytes in the liver of rats treated with biological response modifiers
Luc Bouwens, Eddie Wisse – 1 January 1988 – The numbers of Kupffer cells (macrophages) and pit cells (large granular lymphocytes) were counted by light and electron microscopy in perfusion‐fixed liver sinusoids. After a single intravenous injection of the biological response modifiers zymosan, Propionibacterium acnes and OK‐432, a 4‐ to 6‐fold increase in the number of pit cells and a 2‐ to 4‐fold increase in the number of Kupffer cells were observed within a period of 4 to 7 days.
