We have studied here the effects of ITIM-bearing FcγRIIB2 on the FcεRI-dependent activation of rat basophilic leukemia (RBL-2H3) cells by atomic force microscopy (AFM). AFM images showed that ruffling and degranulation of RBL-2H3 cells were significantly reduced but the cell spreading was not by the co-clustering of FcγRIIB2 and FcεRI. From the results it was shown that the co-clustering of ITIM-bearing...
We have studied the degranulation in rat peritoneal mast cells by atomic force microscopy (AFM). Although AFM has advantages close to electron microscopy (EM) in spatial resolution, visualization of surface topography in peritoneal mast cells has not been reported yet. In the present paper we have succeeded in visualizing the degranulation process of rat peritoneal mast cells by AFM. AFM images showed...
