From the wound of entry, the rabies virus travels quickly along the neural pathways of the peripheral nervous system. The retrograde axonal transport of the rabies virus to the CNS (Central Nervous System) is the key step of pathogenesis during natural infection. The exact molecular mechanism of this transport is unknown although binding of the P protein from rabies virus to the dynein light chain protein DYNLL1 has been shown.[11] P also acts as an interferon antagonist, thus decreasing the immune response of the host.
