Abstract
INTRODUCTION: The available immunohistochemical techniques have documented restricted distribution of vitamins in the mammalian brain. The aim of the study was to develop a highly specific antiserum directed against pantothenic acid to explore the presence of this vitamin in the mammalian brain. MATERIAL AND METHODS: According to ELISA tests, the anti-pantothenic acid antiserum used showed a good affinity (10-8 M) and specificity. The antiserum was raised in rabbits. Using an indirect immunoperoxidase technique, the mapping of pantothenic acid-immunoreactive structures was carried out in the rat brain. RESULTS: Pantothenic acid-immunoreactive perikarya were exclusively found in the intermediate part of the lateral septal nucleus. These cells were generally small, round, fusiform or pyramidal and showed 2-3 long (50-100 μm) immunoreactive dendrites. Any immunoreactive axons containing pantothenic acid were detected. CONCLUSIONS: The very restricted anatomical distribution of the pantothenic acid suggests that this vitamin could be involved in some specific neurophysiological mechanisms.
