adheren junctions
cadherin- Ca2+ dependent adhering molecules
forms a homophilic interaction which mskes strong links between cells
links actin cytoskeleton
cadherin→ catenin→ actin→ myosin
desmosomes
cell- cell junctions
cadherins and intermediate filaments
plentiful in heart muscle and epidermis

hemidesmosomes
attach cells to basal lamina
integrins and intermedate filaments
focal adhesions
e complex protein structures that connect the cell's internal cytoskeleton to the extracellular matrix (ECM). They play a crucial role in cell adhesion, migration, and signaling.
pemphigus
desmoglein is a caherin which holds together kerarinocytes in epidermis
pemphigus is autoimmune skin blistering
role of tight junctions
to prevent fluid and membrane flow
variable extent
transcellular transport
paracellular transport
