Figure Lengend Snippet: M2-immunoreactivity in dendrites without VAchT. A: Abundant M2-immunogold particles (black straight arrows) are nearly exclusively localized on the plasma membrane of a dendrite (M2-d) making a symmetric synapse (white curved arrow) with an unlabeled terminal (ut1) and appositional contacts (white arrowheads) with other unlabeled terminals (ut2,3). B: A transversely-sectioned large dendrite (M2-d1) exhibiting mainly cytoplasmic M2-immunogold particles (black straight arrows) receives multiple contacts from unlabeled terminals (ut1-3) whereas a small nearby dendrite (M2-d2) showing more obvious plasmalemmal M2-immunogold particles (black straight arrows) unveils no evident contact in the plane of section. Intense immunoperoxidase labeling for VAchT is seen in an adjoining axon terminal (VAchT-t). C: Prominent plasmalemmal localization of M2-immunogold particles (black straight arrows) in a dendrite (M2-d) that establishes an apparent symmetric contact (white curved arrow) with an axon terminal (M2-t) having also conspicuous plasmalemmal M2-immunogold (black straight arrows). The inset in the lower left corner shows an enlargement of the contact area illustrating localization of M2-immunogold particle to tubulovesicles attached to the postsynaptic membrane. VAchT-immunoperoxidase product is observed in some small cholinergic axons localized in the near immediacy (VAchT-a1) or more distant (VAchT-a2) to the M2-immunolabeled profiles. D: A longitudinally-sectioned dendrite (M2-d2) showing M2-immunogold (black straight arrows) in the cytoplasm forms extensive contact showing multiple synaptic junctions, most of them with unambiguous symmetric morphology (white curved arrow), with an axon terminal (M2-t) containing M2-immunogold particles, some of which are attached to the presynaptic side of the synapse. The M2-d2 also received a convergent asymmetric synapse (black curved arrow) from an unlabeled terminal (ut). M2-immunogold (black straight arrows) is also seen mainly associated to tubulovesicles (tv) within a nearby larger dendrite (M2-d1) contacting both M2-t and M2-d2. Scale bars = 0.5 μm in A-D.

A: A dually labeled large dendrite (VAchT+M2-d) containing M2-immunogold particles (black straight arrows) mostly localized within the cytoplasm attached to vesicular endomembranes (tv) or to a multivesicular body (mvb) and VAchT-immunoperoxidase labeling (white straight arrows) also condensed especially to tv or mvb has large glial ensheathing (asterisks) but also receives input from unlabeled terminals (ut1,2), one of which is clearly asymmetric (black curved arrow). B: A dendrite (M2-d1) showing both VAchT-immunoperoxidase (white straight arrow) and M2-immunogold particles (black straight arrows) makes an asymmetric synapse (black curved arrow) with an unlabeled axon terminal (ut1) and a quite more symmetric synapse (white curved arrow) with another unlabeled axon terminal (ut2). Prominent plasmalemmal M2-immunogold particles (black straight arrows) are seen in a near dendrite (M2-d2) devoid of VAchT but receiving also input from unlabeled terminals (ut3,4). VAchT-immunoperoxidase is also detected in some small unmyelinated axons (VAchT-a1,2) in the surrounding area.

The VAchT+M2-d is close to a longitudinally-sectioned M2-immunogold labeled dendrite (M2-d1), but intervening astrocytic leaflet keeps apart from apposition each other profile. Several M2-immugold particles (black straight arrows) are seen in some dendrites (M2-d2-4) in one and/or the other of the adjacent serial sections. Abbreviations: asterisks, glial processes.

Figure Lengend Snippet: Schematic diagram showing the primary distributions of M2 muscarinic receptors (M2Rs, stars) in neuronal profiles and glial profiles (g) that express (gray filling) or not (white filling) the vesicular acetylcholine transporter (VAchT, black circles) in the rat mesopontine PPT/LDT complex. The M2R is located in a non-VAchT soma (A) whose dendrites receive synaptic inputs from M2R-labeled, VAchT-labeled and/or unlabeled terminals. In these neurons and in VAchT-labeled neurons (B), the M2R is localized mainly to plasma membranes of dendrites, but is also associated with cytoplasmic membranes in both somata and dendrites. These dendrites receive many symmetric (inhibitory-type) and asymmetric (excitatory-type) synapses from terminals that do not contain either M2R or VAchT, both of which are separately located in nearby axonal and glial processes.
