Association of Cx36 with N-cadherin⁺ adherens junctions at mossy fiber terminals in adult rat ventral hippocampus. (A, B) Low magnification overview of the distribution of N-cadherin⁺ adherens junctions in regions of the ventral hippocampus including the stratum lucidum (A, arrows), and magnification of the boxed area in (A) showing a high density of N-cadherin⁺ adherens junctions in the stratum lucidum (B, arrows). (C) Confocal magnification of the stratum lucidum showing N-cadherin⁺ adherens junctions seen as linear strands in on edge views (C1, arrows) and as discs in en face views (C1, arrowheads). Cx36-puncta in the same field is localized to ZnT3⁺ mossy fiber terminals as seen in red/green overlay (C2, arrows), and N-cadherin⁺ adherens junctions are also localized to those terminals as shown in white/green overlay (C3, arrows), with Cx36-puncta often localized at or adjacent to those junctions as shown in white/red overlay (C4, arrows).
