[Transport of alphaherpesviruses in neurons--axonal"shuttling"].

After a long-term co-evolution, alphaherpesviruses have established mutual adaptability with their hosts. Some alphaherpesviruses have typical neurotropic characteristics, which have received extensive attention and in-depth research. Neurotropic alphaherpesviruses can break through the host barrier to infect neurons and multiply in large numbers in the neuron cell body to complete further proliferation or establish latent infection in the cell body. Either in the process of infecting neurons or further spreading, alphaherpesviruses will undergo transmission along axons or dendrites, so this process is an integral part of the life cycle of the viruses, and is also a key factor for the viruses to spread in nervous system. Therefore, studies on transportation of alphaherpesviruses in neurons will provide new insights of the viruses and promote the development of corresponding vaccines or targeted therapeutic pharmaceuticals. In addition, the neurotropism of alphaherpesviruses is conducive to the analysis of nerve circuits. Herein, the mechanisms of alphaherpesvirus transport in axons were reviewed, and the research direction and application of the transport of alphaherpesviruses in axons were put forward, which can provide reference for the prevention and control of alphaherpesviral infections.
