Modulation of vertebrate and invertebrate neuromuscular junctions.

Advances in our understanding of how the neuromuscular junction is modulated include an expanded appreciation of the many different types of modulatory influences, from soluble factors to second-messenger systems, to specific proteins in nerve and muscle. Recent studies indicate that modulation of neuromuscular function is effected on both the presynaptic and postsynaptic sides of the neuromuscular junction.
