Human Plexin B1 Antibody

Detection of Plexin B1 in Jurkat Human Cell Line by Flow Cytometry.

Jurkat human acute T cell leukemia cell line was stained with Mouse Anti-Human Plexin B1 Monoclonal Antibody (Catalog # MAB37491, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')₂Secondary Antibody (Catalog # F0102B).

SEMA4D triggers receptor-mediated astrocyte reactivity, including changes in astrocyte morphology, expression of key transporters for glutamate recycling and energy metabolism and impairs astrocyte function of glucose uptake. a Primary human astrocyte cultures were stained for PLXN receptors (blue), compared to isotype control antibodies (red). Antibody blocking effect was determined by incubation with rSEMA4D or control protein, in presence/absence of anti-SEMA4D antibody/VX15 (human IgG4) or isotype-matched control antibodies for 48 h. Cultures were stained for b EAAT-2, and c GLUT-1 and MCT-4 transporters. d In a separate experiment, blocking of receptors was assessed using anti-PLXNB1 (mouse IgG1) and/or anti-PLXNB2 (mouse IgG2a) or isotype-matched control antibodies and the same conditions as above. Quantification is shown as; mean + SEM of replicates for each treatment. e Glucose uptake was measured in human astrocyte cultures treated as above. rSEMA4D was added at time 0 and antibodies were added at t = 0 (solid lines and circles) for inhibition or t = 24 h (dotted lines and triangles) to evaluate reversal of activity. Quantification for each condition is shown as average + SEM from 3 wells/condition/timepoint. f Morphologic changes showing length and number of primary processes. For b to f, multivariate regression analysis was performed to determine the effect treatment conditions and dependent variables with treatment type. The significance levels are reported with Tukey post hoc tests for multivariate analysis Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/35933420), licensed under a CC-BY license.
