Hyperactivation of Mincle (Clec4e) in Sh3bp2 mutant mice is linked to exacerbated apical periodontitis after pulp exposure, with Clec4e upregulated versus WT (p<0.0001).
- Why it matters: Apical periodontitis is more prevalent in immune dysfunction, but how the PRR Mincle shapes disease severity and progression in cherubism-like inflammation is unclear.
- What they did: In a CBM autoinflammatory knock-in model, pulp exposure was performed in one lower 1st molar of 5- to 6-week-old mice; Clec gene expression was measured by qPCR, and Mincle was suppressed via Mincle KO/kinase-dead crossing or AptMincle injection.
- The result: Mincle suppression with AptMincle for 21 days significantly ameliorated bone loss versus vehicle in Sh3bp2+/KI mice (p<0.0001), while Sh3bp2+/KIMincle+/+ and Sh3bp2+/KIMincleKO/KO showed comparable bone loss and iNOS, IL-1b, and TNF-a induction.
