Peripheral projections of calretinin-immunoreactive primary sensory neurons in chick hindlimbs.
In chicken dorsal root ganglia, calretinin immunoreactivity is expressed by a subpopulation of large A-neurons, most of which co-express calbindin D-28k. The myelinated axons of these neurons selectively innervate all muscle spindles and most Herbst corpuscles associated to feathers in hindlimbs. It is suggested that the presence of calretinin in primary afferents may be correlated with the electrophysiological properties of rapidly adapting mechanoreceptors.
