SNAREs are the core machinery mediating membrane fusion. In this review, we provide an update on the recent progress on SNAREs regulating membrane fusion events, especially the more detailed fusion processes dissected by well-developed biophysical methods and in vitro single molecule analysis approaches. We also briefly summarize the relevant research from Chinese laboratories and highlight the significant contributions on our understanding of SNARE-mediated membrane trafficking from scientists in China.

Background: Whether to stop oral anticoagulants after a first unprovoked venous thromboembolism (VTE) is challenging, partially due to an intriguingly higher risk of VTE recurrence (rVTE) in men after therapy discontinuation. DNA methylation (DNAm) differences between men and women might underly this sex-biased rVTE risk difference.
Aim: To investigate sex-specific associations between DNAm at cytosine-phosphate-guanine (CpG) sites and rVTE.

The composition of eukaryotic membranes reflects a varied but precise amalgam of lipids. The genetic underpinning of how such diversity is achieved or maintained is surprisingly obscure, despite its clear metabolic and pathophysiological impact. The Arv1 protein is represented in all eukaryotes and was initially identified in the model eukaryote as a candidate transporter of lipids from the endoplasmic reticulum.

Exosomes are small extracellular vesicles secreted by various cell types, playing a crucial role in intercellular communication by carrying proteins, lipids, and nucleic acids, thus holding significant potential in diagnostics and therapeutics. Accurate labeling of exosomes is vital for studying their biogenesis, trafficking, and functional properties, enabling precise tracking and manipulation. This review examines current labeling techniques, including metabolic glycan labeling, chemical tagging, membrane fluorescent dyes, bio-conjugation, non-covalent labeling, and cell-engineering approaches.

Coronaviruses are characterized by their progeny assembly and budding in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC). Our previous studies demonstrated that truncation of 9 amino acids in the cytoplasmic tail (CT) of the infectious bronchitis virus (IBV) spike (S) protein impairs its localization to the ERGIC, resulting in increased expression at the plasma membrane. However, the precise mechanism underlying this phenomenon remained elusive.

NLRP3 is an inflammasome seeding pattern recognition receptor that initiates a pro-inflammatory signalling cascade in response to changes in intracellular homeostasis that are indicative of bacterial infection or tissue damage. Several types of post-translational modification (PTM) have been identified that are added to NLRP3 to regulate its activity. Recent progress has revealed that NLRP3 is subject to a further type of PTM, S-acylation (or palmitoylation), which involves the reversible addition of long-chain fatty acids to target cysteine residues by opposing sets of enzymes.
