Neuron-glial adhesion

Neuron-glial adhesion in nerve cell cultures is mediated by the pi subunit AMOG (adhesion molecule on glia) in the aipi isozyme of Na,K-ATPase [51]. Antibodies to the pi subunit dissociate cell-cell associations and also increase the rate of active... 

Cell adhesion molecules (CAMs) play critical roles in all facets of nervous system development and maintenance. Important phenomena in which CAMs are involved include initial formation of the neural tube and the neural crest, migration of all neurons and glial cells, axonal outgrowth and guidance, target selection, synaptic stabilization and plasticity, myelination and nerve regeneration after injury (see Chs 4,24,28-30 and 53). Adhesion molecules interact with each other and with nonadhesive cell-surface and/or cytoplasmic molecules, and, in the two... 

These neurons know where to go because of a series of remarkable chemical signals, different from neurotransmitters, called adhesion molecules (Table 1—4). First, glial cells form a cellular matrix. Neurons can trace glial fibers like a trail through the brain to their destinations. Later, neurons can follow the axons of other neurons... 

CD56 (also known as neural cell adhesion molecule) is expressed on the cell surface of a number of different tissues including natural killer cells, glial and neurons. This antigen may be demonstrated on monocytic and myeloid leukemias, plasma cell dyscrasias, natural killer cell lesions, neural and astrocytic tumors as well as tumors with neuroendocrine differentiation. Antigen density on hematopoietic tumors tends to be at a lower level than on non-hematopoietic lesions and the validation with flow cytometry determination for this antigen is recommended.
