abstract = {Cannabis is now one of the most commonly used illicit
substances among pregnant women. This is particularly
concerning since developmental exposure to cannabinoids can
elicit enduring neurofunctional and cognitive alterations.
This study investigates the mechanisms of learning and
memory deficits resulting from prenatal cannabinoid exposure
(PCE) in adolescent offspring. The synthetic cannabinoid
agonist WIN55,212-2 was administered to pregnant rats, and a
series of behavioral, electrophysiological, and
immunochemical studies were performed to identify potential
mechanisms of memory deficits in the adolescent offspring.
Hippocampal-dependent memory deficits in adolescent PCE
animals were associated with decreased long-term
potentiation (LTP) and enhanced long-term depression (LTD)
at hippocampal Schaffer collateral-CA1 synapses, as well as
an imbalance between GluN2A- and GluN2B-mediated signaling.
Moreover, PCE reduced gene and protein expression of neural
cell adhesion molecule (NCAM) and polysialylated-NCAM
(PSA-NCAM), which are critical for GluN2A and GluN2B
signaling balance. Administration of exogenous PSA abrogated
the LTP deficits observed in PCE animals, suggesting PSA
mediated alterations in GluN2A- and GluN2B- signaling
pathways may be responsible for the impaired hippocampal
synaptic plasticity resulting from PCE. These findings
enhance our current understanding of how PCE affects memory
and how this process can be manipulated for future
therapeutic purposes.},
