Acute pain transfusion reaction in a patient with thalassemia: In‐depth characterization of short‐ and long‐term phenotypes

Transfusion, EarlyView.
Abstract Background Acute pain transfusion reaction (APTR) is a rare, under‐recognized condition of unknown etiology. It can cause significant distress in recipients, necessitating symptomatic management and, occasionally, hospitalization. Study Design and Methods Here, we present an APTR event in an adult subject with transfusion‐dependent thalassemia

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

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is 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 ...

Sphingosine‐1‐Phosphate Receptor 1 Regulates Competition Dependent Astrocyte Morphogenesis and Tiling in Murine Cortex

Glia, Volume 74, Issue 8, August 2026.
Neuronal contact‐induced expression of S1PR1 in astrocytes is regulated by JAK‐STAT3 signaling. Astrocytic S1PR1 modulates cortical astrocyte morphogenesis. Astrocytic S1PR1 regulates astrocyte territorial overlap/tiling in a competition dependent manner.

Role of the SAFE pathway and the mitochondria in HDL cholesterol (and its constituent sphingosine-1-phosphate) induced cardioprotection

, 2011
High density lipoprotein cholesterol (HDL) and its component sphingosine-1-phosphate (S1P) protect against myocardial infarction. Recently, the SAFE (survivor activating factor enhancement) pathway, involving tumour necrosis factor (TNF) and the ...

Palmitate increases sphingosine-1-phosphate in C2C12 myotubes via upregulation of sphingosine kinase message and activity[S]

Journal of Lipid Research, 2009
Studies in skeletal muscle demonstrate that elevation of plasma FFAs increases the sphingolipid ceramide. We aimed to determine the impact of FFA oversupply on total sphingolipid profiles in a skeletal muscle model.

Sphingosine‐1‐Phosphate Receptor 1 Promotes Ovarian Cancer Tumorsphere Proliferation and Metastasis

International Journal of Cancer, Volume 159, Issue 3, Page 768-781, 1 August 2026.
In high‐grade serous ovarian cancer, malignant ascites frequently arise as ovarian cancer cells shed from the primary tumor and aggregate into tumorspheres, severely limiting treatment success. To date, little is known about the mechanisms governing tumorsphere endurance and metastasis within the ascites once formed.

Generierung von Sphingosin-1-Phosphat durch apoptotische Zellen und dessen Einfluss auf die Polarisierung von Makrophagen während der Tumorentwicklung

, 2008
The removal of apoptotic cells (AC) can be regarded as an integral component of the program to terminate inflammation. Clearance of AC by professional phagocytes such as macrophages induces an anti-inflammatory phenotype in the latter ones.
