Gap Junctions
Gap junctions are sites of intercellular communication where cells are interconnected by small aqueous channels (Figure 1b). The term is morphological, for in transmission electron micrographs of thin sections, the unit membranes of the joined cells are seen to remain separated by a gap of about 2 nm (Figure 1a, inset). The gap of gap junctions distinguishes them from tight junctions, or zonula...
متن کاملGap junctions in development.
Almost since their discovery gap junctions have attracted attention as possible means by which cell growth and cell development could be controlled since they provide for direct cell-cell communication (Potter et al, 1966; Loewenstein, 1968; Sheridan, 1968; Crick, 1970; Bennett, 1973). A corollary, of course, is that gap junctions play an important role in embryogenesis. This idea is made espec...
متن کاملGap junctions
In vertebrates and invertebrates, signaling among neurons is most commonly mediated by chemical synapses. At these synapses neurotransmitter released by presynaptic neurons is detected by receptors on the postsynaptic neurons, leading to an influx of ions through the receptors themselves or through channels activated by intracellular signaling downstream of the receptors. But neurons can commun...
متن کاملon the teacher-generated v.s. leaner-generated noticing-the-gap activities in language classes
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
Gap junctions in C. elegans
As in other multicellular organisms, the nematode Caenorhabditis elegans uses gap junctions to provide direct cell-to-cell contact. The nematode gap junctions are formed by innexins (invertebrate analogs of the connexins); a family of proteins that surprisingly share no primary sequence homology, but do share structural and functional similarity with connexins. The model organism C. elegans con...
