# Progression of herpesvirus infection is inhibited by calcium reporter

## TL;DR

This study shows that a calcium reporter can inhibit the progression of herpesvirus infection by affecting mitochondrial calcium levels.

## Contribution

The study introduces a novel approach using a calcium reporter to interfere with herpesvirus infection progression.

## Key findings

- HSV-1 infection increases mitochondrial calcium and transiently boosts ROS levels.
- Cells with a calcium reporter showed reduced viral replication compartments.
- The calcium reporter's binding interferes with the infection process.

## Abstract

During infection, Herpes simplex virus type 1 (HSV-1) alters the mitochondrial structure and function of the host cell. Live-cell imaging with fluorescent reporters revealed increased mitochondrial calcium and a transient ROS enrichment after HSV-1 infection. Notably, cells co-transfected with a calcium reporter displayed smaller viral replication compartments, while those with a ROS reporter exhibited average growth of viral replication compartments. Our findings suggest that the virus-induced increase in mitochondrial calcium, followed by an increased amount of bound calcium reporter, interferes with the progression of the infection.
