Cryo‐EM and NMR Reveal a Membrane‐Gated Doc2B–Munc13‐1 Complex and a Helical Doc2B‐SNARE‐Binding Interface

open access: yesAdvanced Science, EarlyView.
Biophysical studies of Doc2B yield a cryo‐electron microscopy structure of its complex with the synaptic vesicle priming factor Munc13‐1 and its binding site to the SNARE complex that mediates synaptic vesicle fusion. These and other results suggest a novel model whereby Doc2 proteins regulate neurotransmitter release through sequential interactions ...

ACAT1‐Mediated SP1‐K694 Lactylation Promotes M1 Macrophage Polarization via TREM1 Transcription in COPD

open access: yesAdvanced Science, EarlyView.
Upon cigarette smoke exposure(CSE), LDHA expression is increased in lung macrophages, promoting the conversion of pyruvate to lactate and elevating the lactylation level of SP1 at the K694 site. This, in turn, enhances SP1 enrichment at the TREM1 promoter, increases TREM1 expression, promoted M1 macrophage polarization, and triggers the secretion of ...

Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

open access: yesAdvanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

Quantifying the Dynamics of Network Detachment Across Scientific, Technological, Commercial, and Pharmacological Domains

open access: yesAdvanced Science, EarlyView.
Across scientific, technological, commercial, and pharmacological domains, individuals and organizations disengage from a previously adopted practice not at random, but as their network neighbors detach. The probability of detachment rises with the number of neighbors who have already disengaged. Preferential detachment reshapes network disintegration,
