M1 macrophage‐derived exosomes aggravate diabetic nephropathy by regulating the WTAP/S1PR2 axis

open access: yesJournal of Diabetes Investigation, EarlyView.
ABSTRACT Background Diabetic nephropathy (DN) is a severe microvascular complication of diabetes mellitus. The specific role of M1 macrophage‐derived exosomes in DN progression remains largely unexplored. Methods THP‐1 monocytes were differentiated into M0 macrophages and polarized into M1 macrophages for exosome extraction.

Understanding exosomes in diabetic wound healing

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Diabetic wounds signify a major complication of diabetes mellitus, characterized by chronic inflammation, compromised angiogenesis, and high risk of infection, amputation, and mortality. Contemporary therapies remain limited in efficacy and durability.

Histiocytes: Multifaceted Regulators of Health and Disease

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.

Sphingosine‐1‐Phosphate Attenuates LPS‐Induced Inflammatory Cardiac Injury in Association With RASGRP1–S100A9–NLRP3 Signaling

open access: yesDrug Development Research, Volume 87, Issue 7, November 2026.
ABSTRACT Lipopolysaccharide (LPS) induces endotoxemia‐associated inflammatory cardiac injury rather than classical viral or autoimmune myocarditis. Sphingosine‐1‐phosphate (S1P) regulates cardiovascular and immune responses, predominantly through S1P receptors, but whether it also modulates macrophage‐associated inflammatory signaling during LPS ...

Tumor‐Regional Immune Microenvironment: A Critical Factor in the Design of Radiotherapy–Immunotherapy Combination Trials

open access: yesInternational Journal of Cancer, Volume 159, Issue 8, Page 1857-1872, 15 October 2026.
ABSTRACT Clinical trials combining radiotherapy (RT) with immune checkpoint blockade (ICB) have shown improved outcomes in only a fraction of patients, and optimal strategies for integrating these modalities remain under intense investigation. With a few exceptions, phase III combination trials have yielded disappointing results.

Significance of sphingosine kinase 1 expression in feline mammary tumors

open access: yesBMC Veterinary Research, 2019
Background Sphingosine kinase 1 (SPHK1) is an enzyme that converts pro-apoptotic ceramide and sphingosine into anti-apoptotic sphingosine-1-phosphate.

Tripartite Interplay of Epithelial, Immune, and Microbiota Dysregulation in Crohn's Disease: Mechanisms and Translational Strategies

open access: yesImmunity, Inflammation and Disease, Volume 14, Issue 10, October 2026.
ABSTRACT Background Crohn's disease (CD) is a multifactorial inflammatory bowel disease (IBD) characterized by impaired epithelial barrier integrity, excessive immune hyperactivation, and gut microbiota perturbations. Cumulative evidence supports the role of the intestinal epithelial barrier, immune system and gut microbiota in the progression of CD ...

Estradiol Promotes Tumor Progression in ERα‐Low Endometrial Cancer via the GPER/SphK1 Pathway

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Estradiol (E2) promotes tumor progression in ERα‐low endometrial cancer through the GPER/SphK1/ERK1/2 signaling axis. E2 binding to GPER activates SphK1 and downstream ERK1/2, upregulating Cyclin D1, Cyclin E1, and MMP‐9 to drive cell proliferation, migration, and invasion.
