ABSTRACT
Recent works concerning labile cytoplasmic MT have shown that special MT spatial
(GTP hydrolysis), suggesting that MT may be dissipative structures (Tabony and Job, 1990
Contractile MAPs such as dynein and kinesin participate in ciliary bending as weIl
as intra-neuronal ("axoplasmic") transport which moves material within axons and dendrites
and plays a major role in maintaining and regulating synapses. Other MAPs form structural
bridges and stabilize MT, preventing their disassembly and some may be phosphorylated by
