title: Modulation of lymphocyte-fibroblast interactions by 2-chloro-2'-deoxyadenosine (2-CdA) in subarachnoid hemorrhage.
abstract: The adherence to monolayers of human fibroblasts of chromium-51 labelled peripheral blood mononuclear cells (PBMC) from normal subjects, and from patients after single or multiple subarachnoid hemorrhage (SAH), and the effect of 2-CdA on cell adhesion have been quantified. The fraction of cells adhering to fibroblasts were the lowest for multiple SAH patients and the highest for normal subjects, which can be explained by depletion of activated lymphocytes from peripheral blood of SAH patients. 2-CdA decreased the fraction of adhering cells isolated from normal subjects, did not change the adherence of cells from single SAH patients and increased the fraction of adhering cells isolated from multiple SAH patients. We conclude that the influence of 2-CdA on the adherence of PBMC to fibroblasts is inversely related to the degree of immune system activation.
