At 25 and 40 minutes, the contact sites formed between CTL with active Zap70 and target cells show typical secretory synapses (Stinchcombe et al., 2001b) with flat stretches of tight membrane interactions between the cells surrounding a central intercellular gap between the two cell membranes, termed the secretory cleft.
However, we did not observe fusion between the two cell membranes themselves.
On the other hand, since sperm-oocyte fusion occurs between their two cell membranes, CD81 localized at the inner portion of ZP may be involved in any step of fusion-related events prior to membrane fusion, supporting the function of oocyte CD9 in the fusion.
Consequently, macrophage-like cell fusion events may reflect contact between two cells with altered membranes.
4) In this study, FRAP is used to monitor changes in putative interactions between proteins that occur between two cells and thus in separate membranes.
Reviewer 4: In this study, FRAP is used to monitor changes in putative interactions between proteins that occur between two cells and thus in separate membranes.
These F-actin and microtubule composed membrane tunnels appear to confer cytoplasmic connectivity between two cells similar to TNT structure.
When a plant cell is ready to divide, it needs to produce two new cell membranes, with a new cell wall sandwiched between them, to split the cell contents into two daughter cells.
GJIC is established by the interaction between two hemichannels on adjacent cell membranes.
In support, the interposition of an impermeable membrane between these two cell types prevents the initial growth and regeneration of antlers, whereas a semipermeable membrane does not inhibit but, rather, delays the process [ 22].
