Pathogen proteases and host protease inhibitors in molluscan infectious diseases

Area of Science:

• Marine biology
• Pathology
• Biochemistry

Background:

• Infectious diseases in mollusks arise from complex interactions between pathogen virulence and host defenses.
• Proteases from pathogens and inhibitors from hosts are critical components in these disease processes.
• Metalloproteases (MEROPS Family M4) and serine proteases (MEROPS Family S8) are implicated as mollusk pathogen virulence factors.

Purpose of the Study:

• To review research on pathogen proteases and host protease inhibitors involved in mollusk diseases.
• To highlight the roles of specific protease families and inhibitors in mollusk pathogenesis and defense.
• To identify areas for future research regarding these molecular interactions.

Main Methods:

• Literature review of scientific research on mollusk infectious diseases.
• Analysis of studies focusing on pathogen-derived proteases and host-derived protease inhibitors.
• Examination of genomic and transcriptomic data related to mollusk disease processes.

Main Results:

• Metalloproteases and serine proteases from pathogens are significant virulence factors.
• Mollusk-specific serine protease inhibitors (Family I84) and metalloprotease inhibitors contribute to host defense.
• Genomic and transcriptomic studies suggest a broader involvement of proteases and inhibitors in mollusk diseases.

Conclusions:

• The interplay between pathogen proteases and host protease inhibitors is central to mollusk infectious disease development.
• Further research is warranted to fully elucidate the pathological significance of these interactions.
• Understanding these molecular mechanisms can inform strategies for mollusk disease prevention and control.
