Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

The Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

Axon Initial Segment: Structure, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 4, April 2026.
The axon initial segment (AIS) is a specialized axonal domain critical for maintaining neuronal polarity, action potential initiation, and network stability. This review summarizes the necessary elements for maintaining AIS structure and plasticity, discussing crucial biological functions of AIS in neuronal signaling and the neural circuit homeostasis,

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

Advanced Science, Volume 13, Issue 14, 9 March 2026.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

The dynein microtubule motor

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2000
Dyneins are large multi-component microtubule-based molecular motors involved in many fundamental cellular processes including vesicular transport, mitosis and ciliary/flagellar beating. In order to achieve useful work, these enzymes must contain motor, cargo-binding and regulatory components. The ATPase and microtubule motor domains are located within

Mitophagy and Ubiquitination Coordinate Context‐Specific Mitochondrial Quality Control and EMT/MET Plasticity to Drive Cancer Cell Invasion

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Metastatic invasion emerges when tumor‐intrinsic programs and microenvironmental forces converge on mitochondrial quality control. A context‐stratified framework links mtROS, mtDNA integrity, mechanics and nutrient/oxygen cues to fission–fusion remodeling, mtUPR and mitophagy.

Vimentin Intermediate Filaments: A Paradigm Shift From Static Structure to Dynamic Cytoplasmic Network

BioEssays, Volume 48, Issue 3, March 2026.
Vimentin intermediate filaments form a dynamic, motile network that interacts with microfilaments and microtubules. We propose a hybrid transport model to explain vimentin filament dynamics through cytoskeletal crosstalk and organelle‐associated transport.

Unraveling the Complexities of Kartagener's Syndrome: A Case of Bronchiectasis, Isolated Dextrocardia, and Primary Ciliary Dyskinesia in an Adult With Chronic Respiratory Symptoms

Clinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Kartagener's Syndrome (KS), a rare autosomal recessive disorder and a subset of Primary Ciliary Dyskinesia (PCD), is characterized by chronic sinusitis, bronchiectasis, and, in approximately 50% of cases, situs inversus. This condition arises from genetic mutations that impair motile cilia function, leading to defective mucociliary clearance ...

Ciliary Defects in Inherited Retinal Diseases

Advanced Genetics, Volume 7, Issue 1, March 2026.
The photoreceptor cilium is a specialized sensory organelle essential for vision. This review systematically summarizes the structural and functional defects of the cilium that lead to inherited retinal diseases (IRDs). It highlights key pathogenic genes, elucidates molecular mechanisms of degeneration, and evaluates emerging therapeutic strategies ...
