WebAug 23, 2024 · Most viruses only infect the nervous system accidentally when the immune system is compromised. But some “neurotropic” viruses have evolved to target neurons as part of their normal infectious cycle. The rabies virus, for example, is transmitted when an infected animal bites into a host’s muscle. WebThis allows rabies dG to only infect neurons that express TVA and the rabies glycoprotein. The glycoprotein will be incorporated into the replicating rabies virus envelope, travel retrogradely, and jump the synapse to the previous neuron (Wichersham et al., 2007). However, once rabies dG enters this neuron, it cannot infect any subsequent ... bsccp birmingham https://familysafesolutions.com
