Inflammatory response in molluscs: cross-taxa and evolutionary considerations

Area of Science:

• Evolutionary Biology
• Immunology
• Comparative Physiology

Background:

• Inflammation is a crucial biological process for eliminating damaged tissues and microbes.
• It plays a vital role in homeostasis, wound repair, and immune responses.
• Wound healing in mammals involves a series of biological processes, including inflammation.

Purpose of the Study:

• To review experiments and observations in invertebrate models regarding inflammatory responses.
• To explore the evolutionary origins of molecules involved in inflammation.
• To suggest a common evolutionary origin for inflammatory molecules across divergent taxa.

Main Methods:

• Review of pioneering experiments in invertebrate models.
• Analysis of recent observations in invertebrate models.
• Comparative analysis of inflammatory molecules across molluscs, insects, and vertebrates.

Main Results:

• Invertebrate models provide insights into inflammatory responses.
• Evidence suggests a shared evolutionary origin for molecules driving inflammation.
• Inflammatory responses are conserved across evolutionarily distant taxa.

Conclusions:

• The inflammatory response may be driven by a conserved pool of molecules with a common evolutionary origin.
• This conserved mechanism is present in highly divergent taxa, including invertebrates and vertebrates.
• Understanding these evolutionary links can enhance our knowledge of fundamental biological processes.
