Rarely, p75NTR-labeled terminals are associated with PARV-containing terminals.A, A somata in the granule cell layer is contacted (curved arrow and arrowhead, respectively) by both a PARV-IR axon terminal (PARV-T) and a p75NTR-IR axon terminal (p75-T). B, In the supragranular portions of the molecular layer, a p75NTR-IR axon terminal (p75-T) abuts (curved arrow) a PARV-IR axon terminal (PARV-T) labeled with gold–silver particles (arrowheads).C, An axon terminal in the supragranular layer contains both p75NTR-IR and PARV-IR gold–silver particles (arrowheads). A single-labeled, p75NTR-IR axon terminal (p75-T) nearby forms a symmetric synapse (curved arrow) with an unlabeled dendrite. Scale bars:A, 1.0 μm; B, C, 0.5 μm.
