CAMs such as PSA-NCAM and SYNCAM, as well as several neurexins and neuroligins, differentially affect synaptic functions demonstrated by alterations in NMDA and AMPA receptor-mediated currents, as well as the expression of synaptic protein-mediated aspects of excitatory and inhibitory neurotransmission.

Expression of PSA-NCAM in the Glomerular Layer, Granular Cell Layer, and Olfactory Tract.
Interestingly, the expression of the immature neuronal marker PSA-NCAM was significantly increased in the glomerular layer in PDD/DLB and FTLD only.
We also detected an increased number of cells expressing the immature neuronal marker PSA-NCAM in the glomerular layer of PDD/DLB and FTLD cases, though we were not able to detect DCX expressing cells in the OB regions analyzed.
Taken together, neurogenic and non-neurogenic regions of the human OB from AD, PDD/DLB, and FTLD patients contain PSA-NCAM expressing cells without further signs for the generation of new adult neurons.
