Abstract

Lipid nanoparticles encapsulating miR-192 significantly enhanced vaccine efficacy in aged mice.

  • Excessive proinflammatory cytokines, like IL-6 and TNF-α, were found to reduce antibody production after vaccination.
  • miR-192 demonstrated strong anti-inflammatory effects, improving vaccine performance in older subjects.
  • Transcriptomic analyses indicated that miR-192 downregulated several pro-inflammatory cytokines that negatively affect vaccine responses.
  • miR-192 inhibited critical components of the JAK-STAT signaling pathway, which is important for cytokine signaling in immune cells.
  • These findings suggest that targeting inflammation with microRNA-based approaches could enhance vaccination outcomes in the elderly.
