Fritillaria Alkaloids Target MyD88/TRIF Inflammation
2026-09-01
This study links four Fritillaria isosteroidal alkaloids with suppression of LPS-induced inflammation through coordinated regulation of MyD88-, TRIF-, NF-κB-, and MAPK-associated signaling. By combining RAW 264.7 cell experiments with rat acute lung injury validation, it moves beyond traditional-use claims toward a compound-level, mechanism-oriented evaluation of Fritillaria constituents.

α7nAChR–WNT7B Signaling in Alveolar Repair
2026-09-01
A 2023 JCI Insight study identifies an AT2-cell α7nAChR–WNT7B axis that links cholinergic signaling to alveolar regeneration after acute lung injury. Using AT2-specific genetics, lineage tracing, alveolar organoids, and RNA sequencing, the work shows that α7nAChR activation promotes AT2 proliferation and subsequent AT1 differentiation, while Chrna7 loss worsens repair and inflammation.
