miR-23b-3p deficiency exacerbates immune dysregulation in immunoglobulin A vasculitis by enhancing TLR4-mediated dendritic cell activation

Key Points

To explore the role of miR-23b-3p in regulating immune responses in immunoglobulin A vasculitis (IgAV).
Investigated the effects of miR-23b-3p deficiency on dendritic cell (DC) maturation and function.
Analyzed the TLR4-dependent pathway involved in Tfh differentiation.
Assessed strategies for restoring miR-23b-3p expression to evaluate therapeutic potential.
MiR-23b-3p deficiency worsened IgAV symptoms through increased DC-Tfh axis activation.
Restoring miR-23b-3p expression led to reduced immune dysregulation.

Abstract

miR-23b-3p regulates DC maturation and function and subsequent Tfh differentiation in a TLR4-dependent manner. miR-23b-3p deficiency aggravates IgAV by promoting pathogenic DC-Tfh axis activation, whereas restoration of miR-23b-3p expression attenuates immune dysregulation, suggesting a potential therapeutic strategy for IgAV.
