The dynamics of tight junctions (TJs) and adherens junctions (AJs) under EGTA treatment were investigated in Madin Darby canine kidney (MDCK) cells. Detailed information about the behavior of TJ and AJ proteins during the opening and resealing of TJs and AJs is still scarce. By means of the "calcium chelation" method, the distribution and colocalization of(More)
To examine the dynamics of tight junctions (TJs) in living cells, chimera between the TJ-associated protein ZO-1 and green fluorescent protein (GFP) were constructed. If ZO-1 fused to the C-terminus of GFP (ZO1-CGFP) was stably expressed in MDCK cells, it was fully incorporated into TJs and colocalized with endogenous ZO-1. The GFP tag did not influence(More)
In order to investigate chloroquine retinopathy, the effect of chloroquine on the viability and differentiation of primary cell cultures of embryonic chick neuronal retina, retinal pigment epithelium (RPE), brain and meninges were investigated. The sensitivity of the cells, measured as reduction of viability, showed the following order: RPE greater than(More)
