Learning under stress: a role for the neural cell adhesion molecule NCAM.
Stress is known to be a potent modulator of brain function and cognition. While prolonged and/or excessive stress generally exerts negative effects on learning and memory processes, acute stress can have differential effects on memory function depending on a number of factors (such as stress duration, stress intensity, timing and the source of the stress, as well as the learning type under stud...
متن کاملExpression of neural cell adhesion molecule (NCAM) isoforms in neuroblastoma.
A comparative study on the expression of the neural cell adhesion molecule (NCAM) in human neuroblastoma cell lines and tissues was undertaken. NCAMs are a family of closely related cell surface glycoproteins involved in cell-cell interactions. Using antibodies that recognise distinct epitopes on NCAM, their presence was shown in neuroblastoma, but these studies do not yield any information on ...
متن کاملNeural cell adhesion molecule (NCAM) and myoblast fusion.
Considerable evidence points to an involvement of neural cell adhesion molecule (NCAM) in myoblast fusion. Changes in the level of NCAM expression, isoform specificity, and localization in muscle cells and tissues correspond to key morphogenetic events during muscle differentiation and repair. Furthermore, anti-NCAM antibodies have been shown by others to reduce the rate of myoblast fusion, whe...
متن کاملThe Neural Cell Adhesion Molecule NCAM Is an Alternative Signaling Receptor for GDNF Family Ligands
Intercellular communication involves either direct cell-cell contact or release and uptake of diffusible signals, two strategies mediated by distinct and largely nonoverlapping sets of molecules. Here, we show that the neural cell adhesion molecule NCAM can function as a signaling receptor for members of the GDNF ligand family. Association of NCAM with GFRalpha1, a GPI-anchored receptor for GDN...
متن کاملIdentification of a peptide sequence involved in homophilic binding in the neural cell adhesion molecule NCAM
The neural cell adhesion molecule NCAM is capable of mediating cell-cell adhesion via homophilic interactions. In this study, three strategies have been combined to identify regions of NCAM that participate directly in NCAM-NCAM binding: analysis of domain deletion mutations, mapping of epitopes of monoclonal antibodies, and use of synthetic peptides to inhibit NCAM activity. Studies on L cells...
