Acid ceramidase overactivity drives ceramide loss, leading to atopic dry skin and Th2‐skewed immune polarization

The Journal of Pathology, Volume 269, Issue 2, Page 232-247, June 2026.
Abstract Ceramide deficiency in the stratum corneum (SC) is a key etiological factor in atopic dermatitis (AD). To clarify the direct role of SC ceramide depletion in impairing SC barrier and water‐holding functions and in initiating AD‐like skin symptoms and disease‐specific molecular alterations, we generated Tg mice overexpressing a mutant form of ...

Sphingosine‐1‐Phosphate Promotes FOS Activation in Osteosarcoma Under Tumor Acidosis

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim The tumor microenvironment in solid tumors is characterized by extracellular acidosis, which promotes cancer aggressiveness. In osteosarcoma, the most common primary bone cancer, a highly acidic tumor microenvironment is associated with metastasis and poor prognosis, partly due to metabolic rewiring, including changes in lipid pathways ...

High cholesterol absorption efficiency enhances proatherogenic properties of low‐density lipoprotein particles

Journal of Internal Medicine, Volume 299, Issue 6, Page 711-725, June 2026.
Abstract Background and Aims High cholesterol absorption efficiency is determined by genetic variation in small intestinal sterol transporters and affects one‐third of individuals. Their risk for atherosclerotic cardiovascular disease (ASCVD) is increased compared with low cholesterol absorbers, despite similar serum lipid concentrations.

Trifunctional sphingomyelin derivatives enable nanoscale resolution of sphingomyelin turnover in physiological and infection processes via expansion microscopy

Nature Communications
Sphingomyelin is a key molecule of sphingolipid metabolism, and its enzymatic breakdown is associated with various infectious diseases. Here, we introduce trifunctional sphingomyelin derivatives that enable the visualization of sphingomyelin distribution

Distinct Roles of Myeloid‐ and Hepatocyte‐PLA2G6 Deletion in Mice With Metabolic Dysfunction‐Associated Steatotic Liver Disease

Liver International, Volume 46, Issue 6, June 2026.
ABSTRACT Background and Aims Polymorphisms of group VIA calcium‐independent phospholipase A2 (iPLA2β or PLA2G6) are associated with Type‐2 diabetes, blood lipids and inflammation. Global deficiency in iPLA2β‐null mice elicited protection against hepatic steatosis but not hepatic inflammation after high‐fat diet (HFD) feeding.

Regulated Cell Death in Idiopathic Pulmonary Fibrosis

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
This graphical abstract illustrates regulated cell death (RCD) across key pulmonary cell types—including alveolar epithelial cells, fibroblasts, macrophages, and endothelial cells—modulated through a dynamic death modulation network within the IPF microenvironment.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, Volume 16, Issue 5, Page 944-965, May 2026.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, Volume 16, Issue 5, Page 857-869, May 2026.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Immune Checkpoint Inhibitors and Immunomodulators for Cancer Immunotherapy: Insights Into Resistance and Therapeutic Strategies

Advanced Science, Volume 13, Issue 25, 4 May 2026.
The schematic diagram illustrates the roles of novel immune checkpoints, immunomodulatory factors, cell death and multimodal technologies in cancer immunotherapy. Abstract Cancer immunotherapy has redefined cancer treatment. However, the molecular and cellular basis of immune evasion and therapeutic resistance remains incompletely understood.
