Double immunofluorescence viewed with confocal laser scanning microscopy (CLSM) revealed that VGLUT2+ terminals are distinct from VGLUT1+ terminals. CLSM of Phaseolus vulgaris-leucoagglutinin (PHAL)-labeled cortical or thalamic terminals revealed that VGLUT2 is rare in corticostriatal terminals but nearly normally present in thalamostriatal terminals. Electron microscopy revealed that VGLUT2+ terminals created up 39.four of excitatory terminals in striatum (with VGLUT1+ corticostriatal terminals constituting the rest), and 66.eight of VGLUT2+ terminals synapsed on spines and the remainder on dendrites. VGLUT2+ axo-spinous terminals had a mean diameter of 0.624 lm, though VGLUT2+ axodendritic terminals a imply diameter of 0.698 . In tissue in which we simultaneously immunolabeled thalamostriatal terminals for VGLUT2 and striatal neurons for D1 (with about half of spines immunolabeled for D1), 54.six of VGLUT2+ terminals targeted D1+ spines (i.e., PDE3 Modulator MedChemExpress direct pathway striatal neurons), and 37.three of D1+ spines received VGLUT2+ synaptic contacts. By contrast, 45.four of VGLUT2+ terminals targeted D1-negative spines (i.e., indirect pathway striatal neurons), and only 25.eight of D1-negative spines received VGLUT2+ synaptic contacts. Similarly, among VGLUT2+ axodendritic synaptic terminals, 59.1 contacted D1+ dendrites, and 40.9 contacted D1negative dendrites. VGLUT2+ terminals on D1+ spines and dendrites tended to be slightly smaller sized than those on D1-negative spines and dendrites.
