Modulation of gap junction mediated intercellular communication in TM3 Leydig cells

Modulation of gap junction mediated intercellular communication in TM3 Leydig cells.

Long-term modulation of intercellular communication via gap junctions was investigated in TM3 Leydig cells, under low and high confluence states, and upon treatment of the cells for different times with activators of protein kinase A (PKA) and protein kinase C (PKC). Cells in low confluence were readily coupled, as determined by transfer of the dye Lucifer Yellow; on reaching confluence, the ce...

Gap junction-mediated intercellular communication in the immune system.

Immune cells are usually considered non-attached blood cells, which would exclude the formation of gap junctions. This is a misconception since many immune cells express connexin 43 (Cx43) and other connexins and are often residing in tissue. The role of gap junctions is largely ignored by immunologists as is the immune system in the field of gap junction research. Here, the current knowledge o...

Gap junction-mediated intercellular communication in ischemic preconditioning.

Gap junction-mediated communication can modulate cell death in different tissues. In myocardium, gap junction communication is altered during ischemia, which contributes to the development of arrhythmias, but still allows synchronization of the onset of rigor contracture in the progression of injury. During reperfusion, gap junction communication allows cell-to-cell spread of hypercontracture a...

Regulation 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 ...
