Recent advances in Clp protease modulation to address virulence, resistance and persistence of MRSA infection

Area of Science:

• Microbiology and Molecular Biology: Focuses on bacterial protein degradation and virulence mechanisms.

Background:

• The Clp protease plays a critical role in Staphylococcus aureus (S. aureus) pathogenesis.
• It is involved in protein quality control, virulence factor production, biofilm formation, and persistence.

Purpose of the Study:

• To review recent advancements in understanding the Clp protease's role in S. aureus virulence and persistence.
• To highlight the Clp protease's involvement in methicillin-resistant S. aureus (MRSA) resistance mechanisms.
• To provide an overview of Clp modulators for treating MRSA infections.

Main Methods:

• Literature review of recent studies on Clp protease function in S. aureus.
• Analysis of research on virulence regulation, biofilm, and persister cell formation.
• Examination of studies on toxin-antitoxin systems and Clp protease interactions.
• Overview of therapeutic strategies targeting Clp protease.

Main Results:

• Clp protease controls S. aureus virulence through agr signaling.
• It degrades antitoxins in toxin-antitoxin systems, modulating persister and biofilm formation.
• Clp protease is implicated in MRSA resistance mechanisms.

Conclusions:

• Clp protease is a key regulator of virulence and persistence in S. aureus.
• Targeting Clp protease offers a potential strategy for combating MRSA infections.
