A subpopulation of chicken primary sensory neurons defined by complete co-localization of Peripherin- and ovalbumin-immunoreactivities

In a previous study, we have demonstrated that an ovalbumin-like antigen is present within approximately one-half of all neurons of chicken spinal ganglia. The current study demonstrates this antigen co-localizes absolutely with neural intermediate filament protein (Peripherin) in small to medium-sized neurons of spinal ganglia. While the function of ovalbumin in neurons is unknown, its precise co-localization with Peripherin suggests a functional role restricted to neurons of a defined phenotype.
