Hormonal regulation of gap junction differentiation
Thin-section, tracer, and freeze-cleave experiments on hypophysectomized Rana pipiens larvae reveal that gap junctions form between differentiating ependymoglial cells in response to thyroid hormone. These junctions assemble in large particle-free areas of the plasma membrane known as formation plaques. Between 20 and 40 h after hormone application, formation plaque area increases approximately...

متن کاملRegulation of gap junction coupling in bovine ciliary epithelium.
Aqueous humor is formed by fluid transfer from the ciliary stroma sequentially across the pigmented ciliary epithelial (PE) cells, gap junctions, and nonpigmented ciliary epithelial (NPE) cells. Which connexins (Cx) contribute to PE-NPE gap junctional formation appears species specific. We tested whether small interfering RNA (siRNA) against Cx43 (siCx43) affects bovine PE-NPE communication and...
متن کاملRegulation of connexin biosynthesis, assembly, gap junction formation, and removal.
Gap junctions (GJs) are the only known cellular structures that allow a direct transfer of signaling molecules from cell-to-cell by forming hydrophilic channels that bridge the opposing membranes of neighboring cells. The crucial role of GJ-mediated intercellular communication (GJIC) for coordination of development, tissue function, and cell homeostasis is now well documented. In addition, rece...
متن کاملRegulation of hematopoiesis by gap junction-mediated intercellular communication.
Gap junctions are intercellular channels formed by individual structural units known as connexins (Cx) that allow the intercellular exchange of small molecules between cells. The presence of Cx protein in bone marrow and thymic stromal cells and the demonstration that these cells are functionally coupled have led to the hypothesis that groups of stromal cells in the bone marrow and thymus form ...
