abstract = {Spreading depression (SD), a self-propagating
depolarization of neurons and glia, is believed to play a
role in different neurological disorders including migraine
aura and acute brain ischaemia. Initiation and propagation
of SD modulate excitability of neuronal network. A brief
period of excitation heralds SD which is immediately
followed first by prolonged nerve cell depression and later
by an excitatory phase. The aim of the present study was to
characterize local and remote transmitter receptor changes
after propagation of cortical SD. Quantitative receptor
autoradiography was used to asses 16 transmitter receptor
types in combined striatum-hippocampus-cortex slices of the
rat 1 h after induction of cortical SD. In neocortical
tissues, local increases of glutamate NMDA, AMPA, and
kainate receptor binding sites were observed. In addition to
up-regulation of ionotropic glutamate receptors, receptor
binding sites of GABA(A), muscarinic M1 and M2, adrenergic
alpha(1) and alpha(2), and serotonergic 5-HT(2) receptors
were increased in the hippocampus. Cortical SD also
upregulated NMDA, AMPA, kainate, GABA(A), serotonergic
5-HT(2), adrenergic alpha(2) and dopaminergic D1 receptor
binding sites in the striatum. These findings indicate
selective changes in several receptors binding sites both in
cortical and subcortical regions by SD which may explain
delayed excitatory phase after SD. Mapping of receptor
changes by cortical SD increases our understanding of the
mechanism of SD action in associated neurological
disorders.},
