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.

Targeting sphingosine 1-phosphate and sphingosine kinases in pancreatic cancer: mechanisms and therapeutic potential

Cancer Cell International
Pancreatic cancer is known to be the most lethal cancer. Fewer new treatments are being developed for pancreatic cancer as compared to other cancers. The bioactive lipid S1P, which is mainly regulated by sphingosine kinase 1 (SK1) and sphingosine kinase ...

S1P-S1PR1 Signaling: the “Sphinx” in Osteoimmunology

Frontiers in Immunology, 2019
The fundamental interaction between the immune and skeletal systems, termed as osteoimmunology, has been demonstrated to play indispensable roles in the maintenance of balance between bone resorption and formation. The pleiotropic sphingolipid metabolite,

Structural basis for receptor selectivity and inverse agonism in S1P5 receptors

Nature Communications, 2022
S1P5 is a sphingosine-1-phosphate (S1P) receptor implicated in immune and neurodegenerative disorders. Here, authors report a crystal structure of the S1P5 receptor in complex with a selective inverse agonist, revealing an allosteric subpocket and ...

Defective sphingosine-1-phosphate receptor 1 (S1P1) phosphorylation exacerbates TH17-mediated autoimmune neuroinflammation [PDF]

, 2014
Sphingosine-1-phosphate (S1P) signaling regulates lymphocyte egress from lymphoid organs into systemic circulation. Sphingosine phosphate receptor 1 (S1P1) agonist, FTY-720 (Gilenya™) arrests immune trafficking and prevents multiple sclerosis (MS ...

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 ...
