Chromogranin a Positive Mast Cells in the Dog Paranal Sinus

چکیده
The granin family (Chromogranin A (CgA), 4 Chromogranin B (CgB), Secretogranin (Sg) II, and the less well studied Secretogranins III-VII) comprises a group of acidic proteins that are present in the secretory granules of a wide variety of endocrine and neuro-endocrine cells [6, 22]. There is evidence that granins may be associated to the precursors of biologically active peptides [11, 12, 17]. However, granins cannot be considered simply as precursors of granule cargo. They may act as helper proteins in the packaging of peptide hormones and neuro-peptides [11, 12, 17].

متن کاملMast Cells Kinetics during Experimental Schistosomiasis mansoni in Mice
Increased number of mast cells at the site of infection is widely regarded as important host defense against parasites. The kinetics of mucosal mast cells and connective tissue mast cells responses were studied in the intestines of 68 female CFLP mice infected with 100 Schistosoma mansoni cercariae. The number of mucosal mast cells and the connective tissue mast cells increased from week 3 and ...
متن کاملMast cells density in fibrotic capsule of enchondroma and well-differentiated chondrosarcoma: a method for histopathologic differentiation
Background: An enchondroma is a benign and a well-differentiated chondrosarcoma is an invasive chondroid tumor with high recurrence potential. In spite of biologic differences, these two tumors have very similar histopathologic appearance. It has been shown that the biologic nature of the connective tissue around benign and malignant tumors varies in the number of mast cells. The aim of this s...
