Outline of Final Research Achievements

Organelle transport by kinesin and dynein is deeply related to medical and cosmetic issues. For example, deficit of the transport is a problem as to Alzheimer disease, and melanin pigment produced by sunburn is also transported by kinesin and dynein as melanosomes. The theorems of non-equilibrium statistical mechanics were applied to the in vivo transport because the transport was represented by non-equilibrium stochastic processes. Concretely, we investigated synaptic vesicle precursor transport and melanosome transport. The physical reasons of mis-location of synapses and the effect of dynein inhibitor called ciliobrevin on force and number of motors were clarified.
