• To discuss the necessity and methodologies for studying App-host interactions.
• To highlight the potential of RTX toxin research in understanding App pathogenesis.

Main Methods:

• Literature review of recent App research.
• Discussion of experimental approaches for pathogen-host interaction studies.
• Analysis of the RTX toxin's role in App virulence.

Main Results:

• Recent progress in App research has been updated.
• The dual role of RTX toxin in App infection and immunity is recognized.
• The importance of studying App-host interactions is emphasized.

Conclusions:

• Further research into App RTX toxin-host interactions is crucial.
• Elucidating these interactions will advance our understanding of App molecular pathogenesis.
• This knowledge can inform strategies to mitigate economic losses in the pig industry.
