概要 | We hypothesized that gap junctions mediate intercellular glucose transport in the cochlea in cooperation with facilitative glucose transporter 1 (GLUT1). Immunohistochemistry showed that GLUT1 and the tight junction protein occludin were expressed in blood vessels, and GLUT1, the gap junction proteins connexin26 and connexin30, and occludin were also present in strial basal cells in the lateral wall of the rat cochlea. Gap junctions were found among not only these GLUT1-positive strial basal cells but also GLUT1-negative fibrocytes in the spiral ligaments and strial intermediate cells. Glucose imaging using 6-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-6-deoxyglucose (6-NBDG, MW 342) together with Evans Blue Albumin (EBA, MW 68,000) showed that 6-NBDG was rapidly distributed throughout the stria vascularis and spiral ligament, whereas EBA was localized only in the vessels. |
