Precise immunolocalization of proteins within a cell is central to understanding cell processes and functions such as intracellular trafficking and secretion of molecules during immune responses. Here we describe a protocol for ultrastructural detect

Mast cell (MC) activation through the high-affinity IgE receptor FcεRI leads to the release of mediators involved in immediate-type allergic reactions. Although Abs against the tetraspanins CD63 and CD81 inhibit FcεRI-induced MC degranulation, the

Major basic protein (MBP), the predominant cationic protein of human eosinophil specific granules, is stored within crystalloid cores of these granules. Secretion of MBP contributes to the immunopathogenesis of varied diseases. Prior electron microsc

Mast cell carboxypeptidase A (Mc-cpa) is a highly conserved secretory granule protease. The onset of expression in mast cell progenitors and lineage specificity suggest an important role for Mc-cpa in mast cells. To address the function of Mc-cpa, we

Using mice in which the eGfp gene replaced the first exon of the Il4 gene (G4 mice), we examined production of interleukin (IL)-4 during infection by the intestinal nematode Nippostrongylus brasiliensis (Nb). Nb infection induced green fluorescent pr

The distribution of ribosomes was investigated in mature human mast cells with a chelation-based staining protocol known to bleach DNA-rich structures, leaving RNA-rich structures unbleached. With this method, electron-dense ribosomes were adjacent t

Isolated human lung mast cells were used to identify subcellular sites of basic fibroblast growth factor using a postembedding immunogold method. The factor was present in quantity in secretory granules and cytoplasmic lipid bodies. Cisterns of smoot

Mature human mast cells are classical secretory cells that are filled with secretory-storage granules but are poorly endowed with visible free or membrane-bound cytoplasmic ribosomes. We recently reported close associations of ribosomes and various c

Human mast cells are professional secretory cells that store synthetic products in large granules filling their cytoplasm. Unlike many secretory cells, the principal synthetic organelle, ribosome-rich endoplasmic reticulum, is a minor component of th

The distribution of ribosomes in mature human mast cells, a major granulated secretory cell, does not resemble that in other secretory cells, such as pancreatic acinar cells and plasma cells. By routine ultrastructural analysis, ribosomes in human ma
