Lymphocyte aggregation in response to adrenergic stimulation.
A nonanemic chronic lymphocytic leukemia patient with nearly 500,000 lymphocytes/microL underwent leukapheresis when she presented with CNS symptoms and retinal vascular engorgement. Respiratory distress developed during the cell separator run, which led us to ask whether the procedure could have changed the adhesive properties of her cells. C5a desarginine, N-f-Met-Leu-Phe, adenosine diphospha...
متن کاملLymphocyte stimulation: a rapid multiparameter analysis.
Several parameters of stimulation of individual lymphocytes are measured simultaneously by flow-cytofluorometry after differential staining of cellular DNA and RNA with the metachromatic fluorescent dye acridine orange. The method provides a means of analyzing the progression of stimulated cells through the cell cycle (G1, S and G2 + M), in addition to measuring the accumulation of RNA per cell...
متن کاملInvolvement of gangliosides in lymphocyte stimulation.
N4-Dinitrophenyl-L-2,4-diaminobutyric acid hydrazide was attached covalently to the aldehyde groups produced by periodate oxidate of bovine brain gangliosides and it was incorporated into mature thymocytes. High concentrations of antibodies to dinitrophenyl (DNP) or lower concentrations followed by protein A agglutinated the cells and stimulated DNA synthesis. Incubation of the thymocytes conta...
متن کاملAutologous stimulation of human lymphocyte subpopulation
The background stimulation universally seen when lymphocytes are cultured in vitro has been shown to be markedly lowered by reducing the proportion of B lymphocytes. B-rich fractions of lymphocytes had extremely high background stimulation. It is concluded that stimulation of T cells, probably by autologous B cells, provides the most probable explanation for the findings described.
متن کاملT lymphocyte-dependent B lymphocyte proliferative response to antigen. I Genetic restriction of the stimulation of B lymphocyte proliferation
For the purpose of examining more closely the interaction between T and B lymphocytes, we have developed an in vitro T lymphocyte-dependent B lymphocyte proliferation assay. Proliferation of B lymphocytes in response to antigen was found to depend on the presence of primed T lymphocytes; the B lymphocytes could be derived from nonprimed animals. It appears that these B cells were nonspecificall...
