"All PV[parvalbumin]+ neurons [in CA3 and CA1] were positive for the GABA[gamma aminobutyric acid]A receptor [alpha]1 subunit [reference 31] (Fig._5b-d)."
Interpretation notes: Glutamatergic and GABAergic GABAa alpha1- types in CA1 SLM_SR_SP_SO are probably PV- by contrapositive logic

"In our attempts to identify the CCK[cholecystokinin]-negative subpopulation we found no colocalization of CB1 [cannabinoid type 1] receptor and parvalbumin, as shown previously (Tsou et al., 1999; Katona et al., 1999b, 2000, 2001)."

"The cell bodies immunopositive for each marker are distinct (Fig. 3C), indicating that CB1 [cannabinoid] receptors are not expressed on parvalbumin-containing interneurons."

"In the hippocampus, CCK [cholecystokinin] immunoreactive (CCK-I) terminals were shown to form pericellular baskets around the pyramidal
cell somata and make synaptic contacts on them, and thus some of CCK immunoreactive neurons are considered to be basket cells in this region
[Harris 1985, Hendry 1985, Nunzi 1985]. However, so far our preliminary observations indicated that CCK and PV [parvalbumin] immunoreactivities are not present in the same neuron."
