|
Prevents paracellular movement of solutes; composed of claudins and occludins |
Tight junction (zone occludens) |
|
|
Below tight junction, forms "belt" connecting actin cytoskeletons of adjacent cells with CADherins (Ca2+ dependent Adhesion proteins). Loss of E-cadherin = metastasis. |
Adherens junction (Zonula adherens) |
|
|
Structural support via keratin interactions. Autoantibodies => pemphigus vulgaris. |
Desmosome (macula adherens) |
|
|
Channel protons called connexons permit electrical and chemical communication between cells. |
Gap junction |
|
|
Connects keratin in basal cells to underlying basement membrane. Autoantibodies => bullous pemphigoid. |
Hemidesmosome |
