Meeting report - Alpine desmosome disease meeting 2024: advances and emerging topics in desmosomes and related diseases.

J Cell Sci

January 2025

Institute of Anatomy and Experimental Morphology, Center for Experimental Medicine, University Cancer Center Hamburg, University Medical Center Hamburg-Eppendorf, 20246 Hamburg, Germany.

Desmosomes are adhesive cell contacts abundant in tissues exposed to mechanical strain, such as the stratified and simple epithelia of the epidermis and mucous membranes, as well as the myocardium. Besides their role in mechanical cell cohesion, desmosomes also modulate pathways important for tissue differentiation, wound healing and immune responses. Dysfunctional desmosomes, resulting from pathogenic variants in genes encoding desmosomal components, autoantibodies targeting desmosomal adhesion molecules or inflammation, cause the life-threatening diseases arrhythmogenic cardiomyopathy and pemphigus and contribute to the pathogenesis of inflammatory bowel diseases.

Effects of patent foramen ovale in migraine: a metabolomics-based study.

J Physiol

January 2025

Department of Neurology, West China Hospital, Sichuan University, Chengdu, China.

Patent foramen ovale (PFO), a cardiac anatomical anomaly inducing abnormal haemodynamics, leads to a paradoxical bypass of the pulmonary circulation. PFO closure might alleviate migraines; however, clinical evidence and basic experiments for the relationship are lacking. To explore the effect of PFO on migraine, 371 migraineurs finishing blood tests and contrast transthoracic echocardiography for the detection of PFO were prospectively included.

Low-grade glioma (LGG) is a primary, slow-growing brain tumor; however, its treatment and prognosis remain challenging. In this study, we analyzed cancer data from the TCGA database, focusing particularly on the expression of the CDKN3 gene in LGG. The results showed that high CDKN3 expression in LGG patients was significantly associated with poor survival outcomes.

Female obesity is a worldwide health issue linked to chronic metabolic low-grade inflammation (metaflammation) causing multiple obesity-related co-morbid conditions. We aimed to assess the serum levels of wingless integration site family member 5 A (Wnt5a), leptin, and tumor necrosis factor-alpha (TNF-α) as markers of obesity-associated metaflammation and investigate the association with toll-like receptors2 (TLR2) gene (Arg753Gln) single nucleotide polymorphism (SNP) among Egyptian females. The study included 60 females with obesity and 30 matched controls.

Danlian-Tongmai formula improves diabetic vascular calcification by regulating CCN3/NOTCH signal axis to inhibit inflammatory reaction.

Front Pharmacol

January 2025

National Clinical Research Center for TCM Cardiology, Xiyuan Hospital, China Academy of Chinese Medical Sciences, Beijing, China.

Background: Vascular calcification (VC) commonly occurs in diabetes and is associated with cardiovascular disease incidence and mortality. Currently, there is no drug treatment for VC. The Danlian-Tongmai formula (DLTM) is a traditional Chinese medicine (TCM) prescription used for diabetic VC (DVC), but its mechanisms of action remain unclear.
