چکیده

Skin is the third most zinc (Zn)-abundant tissue in body, In skin, mast cell (MC) granules are enriched Zn. Cellular Zn levels strictly regulated by two groups of transporters: transporters (ZnTs) and Zrt-, Irt-like protein (ZIPs). ZnT expressions were previously determined bone-marrow derived MCs (BMMCs). contrast, little known about ZIP expressions. Thus, aim this study to determine murine MCs. Rodent categorized into connective (CTMCs) mucosal (MMCs). The former latter presumed correspond human tryptase- chymase-positive (MCTC) tryptase-positive (MCT), respectively. CTMCs MCTC constitutively distributed gut lamina propria, pulmonary perivascular tissues, whereas MMCs MCT epithelium lungs. Fetal skin-derived (FSMCs) which obtained as follows; skin from fetal mice was enzymatically digested with trypsin prepare single-cell suspensions. Cells cultured a medium containing IL-3 stem factor for three weeks. Non-adherent cells collected purified using c-kit microbeads. Although FSMCs express various ZIPs mRNA varying degrees, ZIP7 overwhelmingly expressed. BMMCs bone marrow 8-10 w C57BL/6 female isolated same five line result FSMCs, only highly expressed BMMCs. Collectively, we elucidated that both tissue-type mucosal-type facilitates normal dermal development suppresses endoplasmic reticulum stress. We currently investigating function

Murine bone marrow-derived mast cells express chemoattractant receptor-homologous molecule expressed on T-helper class 2 cells (CRTh2).

Mast cells are bone marrow-derived effector cells that can initiate inflammatory responses to infectious organisms or allergens by releasing a multitude of pro-inflammatory factors including prostaglandin (PG) D(2). We demonstrate that primary murine bone marrow-derived mast cells (BMMCs) express the PGD(2) receptor; chemoattractant receptor-homologous molecule expressed on T(h) class 2 cells (...

Mast Cells Express 11 beta-hydroxysteroid Dehydrogenase Type 1: A Role in Restraining Mast Cell Degranulation

Mast cells are key initiators of allergic, anaphylactic and inflammatory reactions, producing mediators that affect vascular permeability, angiogenesis and fibrosis. Glucocorticoid pharmacotherapy reduces mast cell number, maturation and activation but effects at physiological levels are unknown. Within cells, glucocorticoid concentration is modulated by the 11b-hydroxysteroid dehydrogenases (1...
