Prolyl endopeptidase is involved in the degradation of neural cell adhesion molecules in vitro.
Membrane-associated glycoprotein neural cell adhesion molecule (NCAM) and its polysialylated form (PSA-NCAM) play an important role in brain plasticity by regulating cell-cell interactions. Here, we demonstrate that the cytosolic serine protease prolyl endopeptidase (PREP) is able to regulate NCAM and PSA-NCAM. Using a SH-SY5Y neuroblastoma cell line with stable overexpression of PREP, we found...
متن کاملAge-related cognitive impairments in mice with a conditional ablation of the neural cell adhesion molecule.
Most of the mechanisms involved in neural plasticity support cognition, and aging has a considerable effect on some of these processes. The neural cell adhesion molecule (NCAM) of the immunoglobulin superfamily plays a pivotal role in structural and functional plasticity and is required to modulate cognitive and emotional behaviors. However, whether aging is associated with NCAM alterations tha...
متن کاملMorphometrical Study of Polysialylated Neural Cell Adhesion Molecule Positive Cells in Rat Pups Hippocampus Following Induction of Seizure during Pregnancy
Background:The polysialylated neural cell adhesion molecule (PSA-NCAM) is expressed in developing brain. Fetal brain damage is caused by different conditions such as seizure and hypoxia. The present study was designed to investigate the effect of maternal seizures on the number of PSA-NCAM positive cells in pup's hippocampus. Methods: Female Wistar rats were divided into four groups: (a) kindle...
متن کاملMice deficient in the polysialyltransferase ST8SiaIV/PST-1 allow discrimination of the roles of neural cell adhesion molecule protein and polysialic acid in neural development and synaptic plasticity.
Functional properties of the neural cell adhesion molecule (NCAM) are strongly influenced by polysialylation. We used gene-targeting to generate mice lacking ST8SiaIV/PST-1, one of the polysialyltransferases responsible for addition of polysialic acid (PSA) to NCAM. Mice homozygous for the null mutation reveal normal development of gross anatomical features. In contrast to NCAM-deficient mice, ...
متن کاملPathfinding errors of corticospinal axons in neural cell adhesion molecule-deficient mice.
The neural cell adhesion molecule (NCAM) is a cell recognition molecule of the Ig superfamily implicated in cell migration, myelination, and synaptic plasticity, as well as elongation, fasciculation, and pathfinding of axons. Here, we used NCAM-deficient mice to investigate the role of NCAM in the development of the corticospinal tract. We demonstrate severe hypoplasia of the corticospinal trac...
