| pubmed-article:7533636 | pubmed:abstractText | Immunoreactivity to nitric oxide synthase (NOS-IR) was detected in a small population of rat neocortical neurons scattered throughout the frontal, parietal, temporal and occipital cortices. Two-color double-labeling studies revealed that the number of NOS-IR neocortical neurons expressing immunoreactivity to the calcium binding proteins parvalbumin (PV-IR), calbindin-D28K (CB-IR) or calretinin (CR-IR), was low. The absence or low level of calcium binding proteins may imply a reduced Ca2+ buffering capacity in NOS-containing neurons, thereby contributing to their vulnerability to Ca2+ influx through the activated AMPA/kainate receptors reported by others. | lld:pubmed |
