FIG. 1.
NRP1 is up-regulated in activated T cells. Flow cytometry analysis of NRP1 surface expression in activated T cells. Purified primary T cells were stimulated with phytohemagglutinin in the presence of IL-2 (PHA/IL-2) or were incubated with activated dendritic cells (DC-activated). Cell surface NRP1 was detected by cytometry after labeling with phycoerythrin-conjugated control or anti-NRP1 (BDCA4) MAbs.
