The Anti-Infectious Role of Sphingosine in Microbial Diseases

Cells, 2021
Sphingolipids are important structural membrane components and, together with cholesterol, are often organized in lipid rafts, where they act as signaling molecules in many cellular functions.

Western Diet Inhibits FUT7‐Mediated Treg Intestinal Homing to Disrupt the Homeostasis of Intestinal Epithelial Cells in Crohn's Disease

Advanced Science, EarlyView.
In this study, we constructed a nanoparticle that was CD4 antibody‐mediated targeted, Fut7‐expressing plasmid‐loaded cationic liposome, namely CD4‐LDP‐Fut7. Upregulation of Fut7 expression in Tregs by using CD4‐LDP‐Fut7 can increase Treg homing to the intestine, thereby facilitating repair of the intestinal epithelial barrier and inhibiting ...

Impairment of Angiogenic Sphingosine Kinase-1/Sphingosine-1-Phosphate Receptors Pathway in Preeclampsia. [PDF]

PLoS ONE, 2016
Preeclampsia (PE), is a serious pregnancy disorder characterized in the early gestation by shallow trophoblast invasion, impaired placental neo-angiogenesis, placental hypoxia and ischemia, which leads to maternal and fetal morbidity and mortality.

A Systemic Selective Modified mRNA Delivery Platform for Preventing Chemotherapy‐Induced Cardiotoxicity

Advanced Science, EarlyView.
In Yoo and Mainkar et al., we present a minimally invasive, CM‐selective modRNA delivery system encapsulated in lipid nanoparticles for intravenous (IV) administration. This platform enables selective cardiac translation of therapeutic modRNA but suppresses expression in off‐target tissues, including tumors.

⁠Engineering Adaptive Immunity in 3D: A Patient‐Specific Lymphoid Model Using Stromal Networks and Peripheral Blood Mononuclear Cells

Advanced Science, EarlyView.
This study presents a 3D lymphoid tissue model engineered from adipose‐derived stem cells differentiated into fibroblastic reticular cell–like networks and co‐cultured with immune cells. The engineered system successfully generates antigen‐specific antibodies and cytokine responses, providing a platform for studying adaptive immunity, vaccine efficacy,

Sphingosine 1-Phosphate and Atherosclerosis

Journal of Atherosclerosis and Thrombosis, 2018
Sphingosine 1-phosphate (S1P) is a potent lipid mediator that works on five kinds of S1P receptors located on the cell membrane. In the circulation, S1P is distributed to HDL, followed by albumin. Since S1P and HDL share several bioactivities, S1P is believed to be responsible for the pleiotropic effects of HDL.

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, EarlyView.
Doehl et al. discovered an adaptive neuroimmune mechanism that induces itch in tick‐exposed guinea pigs, enabling rapid tick removal. This itch‐induced tick removal (IITR) is mediated by an adaptive cellular immune response and is independent of IgG, IgE, or TRPV1.

F13A1‐Mediated Macrophage Activation Promotes MASH Progression via the PKM2/HIF1A Pathway

Advanced Science, EarlyView.
In fatty liver disease, hepatocytes exposed to palmitate release S1P, which activates calcium signaling in macrophages. Elevated calcium enhances the activity of F13A1, driving PKM2 dimerization. The PKM2 dimers cause Warburg effect, translocate to the nucleus, cooperate with HIF1A, and upregulate IL1B expression, ultimately promoting classical ...

Sphingosine‐1‐phosphate and renal vasoconstriction [PDF]

Acta Physiologica, 2017
In the present issue of Acta Physiologica, Guan et al. in their article “Mechanisms of sphingosine-1-phosphate-mediated vasoconstriction of rat afferent arterioles” 1 address the signaling events associated with sphingosine-1-phosphate (S1P)-mediated renal afferent vasoconstriction and show in, technically demanding, blood-perfused juxtamedullary ...

Sphingosine Kinase 1 Cooperates with Autophagy to Maintain Endocytic Membrane Trafficking

Cell Reports, 2016
Sphingosine kinase 1 (Sphk1) associates with early endocytic membranes during endocytosis; however, the role of sphingosine or sphingosine-1-phosphate as the critical metabolite in endocytic trafficking has not been established. Here, we demonstrate that
