Centronuclear myopathy (CNM) is a congenital myopathy characterised by centralised nuclei in skeletal myofibers. T-tubules, sarcolemmal invaginations required for excitation-contraction coupling, are disorganised in the skeletal muscles of CNM patients. Previous studies showed that various endocytic proteins are involved in T-tubule biogenesis and their dysfunction is tightly associated with CNM pathogenesis. and are two causative genes for CNM that encode essential membrane remodelling proteins in endocytosis, dynamin 2 and BIN1, respectively. In this review, we overview the functions of dynamin 2 and BIN1 in T-tubule biogenesis and discuss how their dysfunction in membrane remodelling leads to CNM pathogenesis.

Radiotherapy (RT) is a key component of comprehensive cancer treatment regimens; nevertheless, its concomitant immunosuppression may diminish therapeutic efficacy. In this study, we developed an injectable hydrogel system for the local delivery of PROteolysis TArgeting Chimeras (PROTACs), achieved by loading tumor cell membrane-fused liposome nanoparticles to enhance the anti-tumor effect. The system targeted Bromodomain-containing protein 4 (BRD4), and combined treatment with RT promoted DNA damage, reduced DNA repair and decreased tumor cell proliferation and survival.

Nanoplastics (NPs) in marine ecosystems have garnered increasing attention for their interference with the physiological processes of aquatic organisms. An in-depth examination of the toxicological responses of Nannochloropsis oceanica, a species vital to marine ecosystems, is essential due to the crucial role of lipid metabolism in carbon sequestration and energy allocation in microalgae. This study analyzed the toxicological responses of N.

Cholesterol-dependent cytolysins (CDCs) constitute the largest group of pore-forming toxins and serve as critical virulence factors for diverse pathogenic bacteria. Several CDCs are known to activate the NLRP3 inflammasome, although the mechanisms are unclear. Here we discovered that multiple CDCs, which we referred to as type A CDCs, were internalized and translocated to the trans-Golgi network (TGN) to remodel it into a platform for NLRP3 activation through a unique peeling membrane mechanism.

Bolaamphiphiles─amphiphilic molecules with polar groups at each of the two ends of a hydrophobic tail with pH-sensitive spontaneous molecular curvatures, endow membranes of extremophiles with an exquisite balance between stability (or robustness) and adaptability (or plasticity). But how the presence (or real-time insertion) of bolaamphiphiles influences lamellar lipid membranes is poorly understood. Using a combination of time-resolved confocal fluorescence microscopy, in situ small-angle X-ray and neutron scattering (SAXS and SANS), and neutron spin echo (NSE) measurements, we monitor here the pH-dependent interactions of nanoscopic vesicles of a representative bolaamphiphile─a glucolipid consisting of a single glucose headgroup and a C18:1 (oleyl) fatty acid tail (G-C18:1)─with the membranes of an essentially cylindrical fluid-phase phospholipid (dioleoylphosphatidylcholine, DOPC).

Cilia, evolutionarily conserved organelles on eukaryotic cell surfaces, depend on the intraflagellar transport (IFT) system for their assembly, maintenance, and signaling. The IFT system orchestrates bidirectional trafficking of structural components and signaling molecules through coordinated actions of protein complexes and molecular motors. IFT complexes assemble into anterograde trains at the ciliary base and undergo structural remodeling at the ciliary tip to form retrograde trains, with bidirectional motility regulated by modifications on the trains per se and the microtubule tracks.
