The localization of meprobamate-like (MPB-like) molecules in the neuromuscular junction of rats has been investigated at light- and electron- microscopic levels with the peroxidase-antiperoxidase (PAP) immunohistochemical method, using a purified antiserum obtained from rabbits immunized with a meprobamate-bovine serum albumin (MPB-BSA) conjugate. The immunoreaction was found surrounding synaptic vesicles and in protuberant deposits situated in the post-synaptic membrane. These facts suggest the existence of endogenous MPB-like molecules in neuromuscular junction and that the immunostained protuberant deposits should mark the receptors of those molecules.
