Analysis of Adhesion Molecules and Basement Membrane Contributions to Synaptic Adhesion at the Drosophila Embryonic NMJ
Synapse formation and maintenance crucially underlie brain function in health and disease. Both processes are believed to depend on cell adhesion molecules (CAMs). Many different classes of CAMs localise to synapses, including cadherins, protocadherins, neuroligins, neurexins, integrins, and immunoglobulin adhesion proteins, and further contributions come from the extracellular matrix and its r...
متن کاملLoss of adhesion to basement membrane components but not to keratinocytes in proliferating melanocytes.
We studied the adhesive characteristics of melanocytes, cultured either in the presence of the mitogen phorbol 12-myristate 13-acetate (PMA) that keeps them in a proliferative state, or in the absence of PMA allowing them to differentiate. On proliferating melanocytes, several integrins, ICAM-1, E-cadherin, and CD44 were expressed. In the absence of PMA, proliferation was arrested, melanin synt...
متن کاملExpression of integrins and basement membrane components by wound keratinocytes.
Extracellular matrix proteins and their cellular receptors, integrins, play a fundamental role in keratinocyte adhesion and migration. During wound healing, keratinocytes detach, migrate until the two epithelial sheets confront, and then regenerate the basement membrane. We examined the expression of different integrins and their putative ligands in keratinocytes during human mucosal wound heal...
متن کاملIntegrin Complex Is Located in Hemidesmosomes, Suggesting a Major Role in Epidermal Cell-Basement Membrane Adhesion
The ot6//34 complex is a member of the integrin family of adhesion receptors. It is found on a variety of epithelial cell types, but is most strongly expressed on stratified squamous epithelia. Fluorescent antibody staining of human epidermis suggests that the /~4 subunit is strongly localized to the basal region showing a similar distribution to that of the 230-kD bullous pemphigoid antigen. T...
متن کاملMulti-walled carbon nanotube interactions with human epidermal keratinocytes.
Carbon nanotubes have widespread applications in multiple engineering disciplines. However, little is known about the toxicity or interaction of these particles with cells. Carbon nanotube films were grown using a microwave plasma enhanced chemical vapor deposition system. Human epidermal keratinocytes (HEK) were exposed to 0.1, 0.2, and 0.4 mg/ml of multi-walled carbon nanotubes (MWCNT) for 1,...
