Identification of histamine-receptor leukocytes in the bovine

Subpopulations of leukocytes have been characterized by using cell surface membrane markers, and attempts have been made to correlate membrane receptors with cellular function. Histamine receptors on cell membranes have been identified in the mouse, man and rhesus monkey by numerous methods. In this study, an immunofluorescent technique was used to identify and enumerate histamine-receptor leukocytes in the peripheral blood of cattle. This report appears to be the first documenting these cells in the bovine.
