Interferon-inducible GTPase: a novel viral response protein involved in rabies virus infection

Abstract

Rabies virus infection is a major public health concern because of its wide host-interference spectrum and nearly 100 % lethality. However, the interactions between host and virus remain unclear. To decipher the authentic response in the central nervous system after rabies virus infection, a dynamic analysis of brain proteome alteration was performed. In this study, 104 significantly differentially expressed proteins were identified, and intermediate filament, interferon-inducible GTPases, and leucine-rich repeat-containing protein 16C were the three outstanding groups among these proteins. Interferon-inducible GTPases were prominent because of their strong upregulation. Moreover, quantitative real-time PCR showed distinct upregulation of interferon-inducible GTPases at the level of transcription. Several studies have shown that interferon-inducible GTPases are involved in many biological processes, such as viral infection, endoplasmic reticulum stress response, and autophagy. These findings indicate that interferon-inducible GTPases are likely to be a potential target involved in rabies pathogenesis or the antiviral process.
