Randomized trial demonstrates the role of resistin-like molecules in enhancing antiviral defense in allergic inflammation, suggesting therapeutic potential.
Key Points
This research aims to examine the role of resistin-like molecules (RELMs) in modulating lung immunity during influenza, particularly in the context of allergic asthma.
Utilized knockout and gain-of-function approaches in mice to study RELMs' effects.
Performed scRNA sequencing to analyze gene expression in immune and structural cells during influenza.
Administered recombinant RELMα and RELMβ intranasally to assess their impact on lung viral burden and airway mechanics.
Knockout mice showed distinct viral clearance patterns compared to wild-type, indicating the influence of RELMs on influenza pathogenesis.
RELM-deficiency resulted in worsened airway physiology post-infection, highlighting a protective role for these proteins.
RELM treatment significantly reduced lung viral burden and improved airway mechanics, altering the airway immune landscape with increased macrophages and CD8+ T cells.
