A Study of the Mechanisms of Attachment of Allergised Lymphocytes to BP8 Ascites Tumour Cells

摘要

The attachment of allergised and non-allergised lymph-node cells from C57B1 mice to BP8 ascites tumour cells were compared in vitro in the presence of vaso-active agents and mediators of the inflammatory reaction. It was found that Priscol, noradrenaline, adrenaline, 5-HT and histamine caused some cell adherence, while bradykinin and lysolecithin caused a marked increase of adherence of the allergised lymph-node cells to the BP8 cells. Electrophoretic studies of BP8 cells in the presence of polyornithine showed an abolition of the anodic mobility. Theories of action of the various agents are discussed.
