Is activation of protein kinase C required for AMPA receptor GluR1 phosphorylation at serine 845 in the dorsal striatum following repeated cocaine administration?
These findings suggest that phosphorylation of AMPA receptors at GluR1-S845 is upregulated by interactions of glutamate receptor-coupled Ca(2+)-dependent protein kinases following repeated cocaine administration in the dorsal striatum.
Human explant derived VSMC systematically differ from enzyme dispersed VSMC obtained from the same donor tissue. Wherever the potential role of TGF beta was investigated, the differences between enzyme dispersal and explant cultures were due to autocrine production of TGF beta by the enzyme dispersal, but not explant cultures.
