The pH of the skin surface and its impact on the barrier function [PDF]

, 2006
The `acid mantle' of the stratum corneum seems to be important for both permeability barrier formation and cutaneous antimicrobial defense. However, the origin of the acidic pH, measurable on the skin surface, remains conjectural.

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, Volume 13, Issue 25, 4 May 2026.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

Localization of nuclear actin in nuclear lipid microdomains of liver and hepatoma cells: Possible involvement of sphingomyelin metabolism [PDF]

, 2017
Nuclear actin has been implicated in different nuclear functions. In this work, its localization in nuclear membrane, chromatin and nuclear lipid microdomains was investigated. The implication of sphingomyelin metabolism was studied.

Lipidome Analysis of Cancer Cells and Their Extracellular Vesicles Reveals Cancer‐Type‐Specific Lipid Signatures and Enables the Design of EV‐Mimetic Liposomes

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT Lipid metabolism reprogramming is a hallmark of cancer, yet the global lipidome of cancer cells and their extracellular vesicles (EVs) remains poorly understood. Using mass spectrometry, we analyzed the lipid profiles of a panel of human cancer and non‐cancer cell lines along with their secreted EVs.

2025 Consensus Clinical Management Guidelines for Niemann‐Pick Disease Type C

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT In 2018, the International Niemann‐Pick Disease Alliance (INPDA) and the International Niemann‐Pick Disease Registry (INPDR) developed and published comprehensive clinical management guidelines to support inclusive and standardized care pathways in Niemann‐Pick disease type C (NPC)—an ultra‐rare, autosomal recessive, neurovisceral lysosomal ...

A role for neutral sphingomyelinase activation in the inhibition of LPS action by phospholipid oxidation products

Journal of Lipid Research, 2006
Previous studies from our laboratory and others presented evidence that oxidized 1-palmitoyl-2-arachidonyl-sn-glycero-3-phosphatidylcholine (OxPAPC) and oxidized 1-palmitoyl-2-arachidonyl-sn-glycero-3-phosphatidylethanolamine can inhibit ...

Adults With Acid Sphingomyelinase Deficiency Have Sustained Improvements in Clinical Outcomes With up to 5 Years of Olipudase Alfa Enzyme Replacement Therapy: ASCEND Trial Final Results

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT Acid sphingomyelinase deficiency (ASMD) is a rare debilitating lysosomal storage disease resulting in multisystemic disease manifestations, significant disease burden, and early mortality for some individuals. Enzyme replacement therapy (ERT) with olipudase alfa (Xenpozyme) is the first disease‐specific treatment indicated for noncentral ...

Upregulation of sphingomyelin and ABCA8 in response to TDP‐43 pathology in amyotrophic lateral sclerosis brain

Brain Pathology, Volume 36, Issue 3, May 2026.
Increases in sphingomyelin in response to TDP‐43 pathology in the disease‐affected motor cortex of amyotrophic lateral sclerosis (ALS) brain. Abstract Amyotrophic lateral sclerosis (ALS) is a rapidly progressing neurodegenerative disease characterized by the degeneration of motor neurons and the presence of TAR DNA‐binding protein 43 (TDP‐43 ...
