Pathogenesis and Therapeutics for Chronic Pruritus of Unknown Origin: A Systematic Review

open access: yesInternational Journal of Dermatology, Volume 65, Issue 4, Page 706-723, April 2026.
ABSTRACT Chronic pruritus of unknown origin (CPUO) is a distressing condition characterized by persistent itch lasting over 6 weeks without an identifiable cause. The underlying mechanisms remain poorly understood, complicating diagnosis and treatment.

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Laurdan: Clarifying Photophysics and Advancing the Characterization of Extracellular Vesicles

open access: yesChemPhysChem, Volume 27, Issue 5, 13 March 2026.
Biophysical properties of extracellular vesicles (EVs) reflect their composition and membrane organization. We introduce a novel approach using time‐resolved emission spectra (TRES) phasor analysis of the polarity‐sensitive probe Laurdan to characterize membranes with complex compositions.

The Microbiota Shapes Central Nervous System Myelination in Early Life

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Gut microbiota shapes brain development by regulating myelination and glial cell maturation in early life. Using germ‐free (GF) mice and zebrafish, this study reveals sex‐ and age‐dependent effects on myelin growth, integrity, and related gene expression.

F13A1‐Mediated Macrophage Activation Promotes MASH Progression via the PKM2/HIF1A Pathway

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
In fatty liver disease, hepatocytes exposed to palmitate release S1P, which activates calcium signaling in macrophages. Elevated calcium enhances the activity of F13A1, driving PKM2 dimerization. The PKM2 dimers cause Warburg effect, translocate to the nucleus, cooperate with HIF1A, and upregulate IL1B expression, ultimately promoting classical ...
