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

Journal 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.

Regulation and function of sphingosine kinase 2 in diseases [PDF]

, 2018
Sphingosine kinase functions to phosphorylate sphingosine to sphingosine 1-phosphate (S1P) to keep balance in the metabolites of sphingolipids. There are two isoforms of sphingosine kinase, sphingosine kinase 1 (SphK1) and sphingosine kinase 2 (SphK2).

Understanding exosomes in diabetic wound healing

Periodontology 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

Veterinary 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 analogue drug FTY720 targets I2PP2A/SET and mediates lung tumour suppression via activation of PP2A‐RIPK1‐dependent necroptosis

EMBO Molecular Medicine, 2012
Mechanisms that alter protein phosphatase 2A (PP2A)‐dependent lung tumour suppression via the I2PP2A/SET oncoprotein are unknown. We show here that the tumour suppressor ceramide binds I2PP2A/SET selectively in the nucleus and including its K209 and Y122

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

Drug 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 ...

Sphingosine kinase 2 deficiency increases proliferation and migration of renal mouse mesangial cells and fibroblasts [PDF]

, 2015
Both of the sphingosine kinase (SK) subtypes SK-1 and SK-2 catalyze the production of the bioactive lipid molecule sphingosine 1-phosphate (S1P). However, the subtype-specific cellular functions are largely unknown.

SphK1/S1P信号通路在脑缺血再灌注神经细胞损伤机制中的研究进展 Progress of SphK1/S1P Signaling Pathway in the Mechanism of Cerebral Ischemia Reperfusion Injury

Zhongguo cuzhong zazhi, 2018
神经鞘磷脂及其代谢产物——神经酰胺、鞘氨醇（sphingosine，Sph）、鞘氨醇-1-磷酸 （sphingosine-1-phosphate，S1P）作为重要的信号传递分子在细胞增殖、存活、凋亡及炎症免疫等病理生 理过程中发挥重要作用，鞘氨醇激酶（sphingosine kinase，SphK）是催化Sph生成S1P的关键酶。脑缺血再 灌注损伤涉及兴奋性毒性、神经炎症及氧化应激、自由基生成、血脑屏障损伤、细胞死亡等多种机 制。本文主要阐述SphK1及S1P的功能特点，及脑缺血再灌注损伤涉及的机制 ...

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

International 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.

Sphingosine 1-phosphate signalling contributes to transforming growth factor-β1-induced myofibroblast differentiation in oral cancer [PDF]

PeerJ
The prognosis for patients with oral squamous cell carcinoma (OSCC) is poor and novel ways to manage the disease are required. The density of myofibroblastic cancer-associated fibroblasts (myoCAFs) within the OSCC stroma correlates with poor prognosis ...
