Distribution of growth associated protein (GAP-43) immunoreactivity in nerve fibers supplying the pig pineal gland.
An immunohistochemical study of the pig pineal gland was carried out using monoclonal mouse antiserum against growth-associated protein GAP-43. The pineal glands were obtained from the 3, 5, 8 weeks old piglets. The immunopositive nerve fibers were observed in the pineal gland as well as in the habenular and the posterior comissural areas. They formed a dense network in the habenular area and the proximal part of the pineal gland. In the comissural area and in the apical part of the gland. single positive fibers were observed. The obtained results may suggest a difference in the plasticity of innervation between the particular regions of the pineal gland.
