A
Cell-matrix interaction
Cell-Cell interaction
2
Q
List the functional classes of cell junctions
A
- anchoring junctions
- occluding junction
- channel forming junctions
- signal relay junctions
3
Q
What are anchoring junctions?
A
Between cells and matrix.Transmit stresses. tethering between ECM and cytoskeleton or between two cells linking them to the cytoplasm.
4
Q
What are Occluding junctions?
A
These seal gaps between cells in epithelia to make the sheet an impermeable barrier.
5
Q
What are channel forming junctions?
A
Create passageways linking the cytoplasms of adjacent cells
6
Q
What are signal relay junctions?
A
Allo signals to be relayed to one another through the plasma membrane.
7
Q
What does MMP stand for?
A
Matrix mellaproteinases
