ECM Flashcards
1
Q
Homophillic interactions
A
Cadherins
Ig superfamily
- Used in cell -cell interactions
2
Q
Heterophilic interactions
A
Selectins
Integrins
- Used in transit cell cell or cell matrix interactions
3
Q
Integrins
A
bridge b/t intracellular and extracellular molecules
intracellular- binds actin and proteins
Extracellular- bind ECM proteins
4
Q
WBC migration
A
selectins and integrins
5
Q
Tight junctions
A
seal between epithelial cells. (Occluding and Claudius major transmamebrane proteins)
6
Q
Adherens junctions
A
(Zonula Adherins) Connects Actin filaments
7
Q
Desmosomes
A
Connects IF (cell to cell)
8
Q
Gap junctions
A
allows passage of small water soluble molecules (connexons)
9
Q
Hemidesmosomes
A
Anchors IF in a cell to ECM manner.
