Abstract

Cholesterol-25-hydroxylase (CH25H) is a reticulum-associated membrane protein that catalyzes the oxidation of cholesterol to 25-hydroxycholesterol (25HC). Recent studies have revealed that CH25H is an interferon-stimulated gene (ISG) that suppresses infection by several viruses. In the present study, we found that overexpression of both human and murine CH25H inhibited rabies virus (RABV) infection in HEK-293T (293T) cells. In contrast, silencing of CH25H enhanced RABV replication in 293T cells, and a catalytic mutant of CH25H lost its ability to inhibit RABV infection. Treatment with the oxysterol 25-hydroxycholesterol (25HC), the product of CH25H, dramatically decreased RABV replication in 293T, BSR and N2a cells by inhibiting viral membrane penetration. These data provide insights into the antiviral function of CH25H against RABV infection, which can potentially be used as a therapeutic agent for rabies.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
