The Takeaway

The virus uses a protein called pUL56 to strip sodium and potassium channels off the surface of neurons. This leaves the brain cells physically intact but electrically dead, completely unable to send signals or communicate with the rest of the brain.

From the abstract

Herpes simplex virus 1 (HSV-1) infections of the central nervous system cause encephalitis and are associated with increased risk of neurodegeneration, yet the molecular consequences of lytic infection in human neurones remain incompletely defined. We map the transcriptomic, proteomic and surface-proteome changes induced by HSV-1 across the lytic infection cycle in human iPSC-derived cortical glutamatergic neurones. HSV-1 drives extensive plasma-membrane remodelling, including the removal of vol
