Rabies Virus Exploits Cytoskeleton Network to Cause Early Disease Progression and Cellular Dysfunction

Area of Science:

• Neurovirology
• Cell Biology
• Pathogenesis

Background:

• Rabies virus (RABV) is a significant neurotropic pathogen causing neglected tropical diseases.
• RABV infection leads to neuronal dysfunction by interfering with the actin and microtubule cytoskeleton.
• The precise mechanisms of viral-cytoskeleton interaction and their role in viral progression remain unclear.

Purpose of the Study:

• To systematically review and interpret scientific findings on cytoskeleton elements and RABV interactions.
• To elucidate the pathogenesis of RABV by understanding its progression within host cells.
• To identify potential therapeutic targets at the subcellular level.

Main Methods:

• Systematic review of existing scientific literature on RABV and cytoskeleton interactions.
• Interpretation of collected data to explain RABV's pathogenic mechanisms.
• Analysis of viral-host protein interactions, focusing on cytoskeleton-associated proteins.

Main Results:

• RABV deregulates actin and microtubule polymerization, causing neuronal dysfunction.
• The virus manipulates microtubules and motor proteins, and utilizes actin for cellular entry.
• RABV's phosphoprotein (P) is crucial, orchestrating dynein motor protein function for viral replication and transport.

Conclusions:

• RABV extensively interacts with the host cell cytoskeleton, leading to degenerative changes.
• Targeting cytoskeletal destabilization offers a promising avenue for novel antiviral therapies.
• Further research into subcellular interactions is essential to combat RABV infection.
