Peripherin fibers in the main olfactory bulb are different from olfactory fibers and from LHRH fibers: an immunocytochemical and DiI study.
Fibers coming from the olfactory epithelium and entering the olfactory bulb expressed peripherin. These were not sensory olfactory fibers because: (1) they did not form glomeruli, (2) they did not express olfactory marker protein (OMP), (3) they entered deeply into the olfactory bulb, reaching its white matter. Cells and fibers in the olfactory bulb expressing luteinizing hormone-releasing hormone (LHRH) differed from those expressing peripherin because LHRH and peripherin did not coexist and the distributions of LHRH-positive and peripherin-positive fibers were found to be different.
