Toll-like receptor 5 (TLR5)–positive Aβ afferent innervating protein kinase C γ expressing (PKCγ+) neurons. (A) Double staining of tdTomato with TLR5 antibody on sagittal lumbar spinal cord slices of 3-week-old Prkcg-P2A-tdTomato mice. (B) TLR5-positive fibers made close contact with the cell body of genetically labeled PKCγ+ neurons. (C) TLR5-positive fibers made close contact with the cell body and dendrites of PKCγ+ neurons labeled by intracellular biocytin. Arrowheads indicate the contact points on the cell body. Arrows indicate the contact points on the dendrites.
