• cgSHAPE-seq Maps SARS-CoV-2 RNA-Degrader Binding

  2026-08-27

  The reference study introduces cgSHAPE-seq, a sequencing-based strategy that converts ligand-directed RNA acylation into reverse-transcription mutations to identify small-molecule binding sites. Applied to the SARS-CoV-2 5′ UTR, the method mapped a coumarin-binding bulged G in SL5 and guided development of an RNase L-recruiting chimera that reduced viral replication in cultured cells.

• PVT VGluT2 Neurons Link Parkinson’s Disease to Depression

  2026-08-27

  This study identifies VGluT2-positive neurons in the paraventricular thalamic nucleus as a circuit-level driver of depression-like phenotypes in paraquat-induced Parkinson’s disease. By combining cell-type-specific manipulation with projection analysis, the work places the PVT–central amygdaloid nucleus pathway upstream of glutamatergic and structural changes associated with affective dysfunction.

• Berberine, SIRT6-AMPK, and Atrial Fibrillation

  2026-08-26

  A recent International Immunopharmacology study identifies SIRT6-AMPK signaling as a protective axis against angiotensin II-induced atrial remodeling and atrial fibrillation susceptibility.

• ML365 and NLRP3 Signaling in Aged-Mouse POCD

  2026-08-25

  A 2024 Brain Research study found that ML365 pretreatment reduced postoperative cognitive impairment in aged mice after exploratory laparotomy, alongside lower hippocampal NLRP3 inflammasome markers, less hippocampal injury, and reduced plasma malondialdehyde. The work connects two-pore domain potassium-channel pharmacology with postoperative neuroinflammation, while leaving direct TASK1 engagement and clinical translation unresolved.
