    World Journal of Biological Chemistry 1(11):321 (2010) PMID 21537466 PMCID PMC3083938

    The importance of sphingosine kinase (SphK) and sphingosine-1-phosphate (S1P) in inflammation has been extensively demonstrated. As an intracellular second messenger, S1P plays an important role in calcium signaling and mobilization, and cell proliferation and survival. Activation of various pla...
  11. Temporal transcriptomic profiling reveals cellular targets that govern survival in HOCl-mediated neuronal apoptosis.

    Life Sciences 87(15-16):457 (2010) PMID 20837029

    With the identification of hypochlorous acid (HOCl) as a biomarker in diseased brains and endogenous detection of its modified proteins, HOCl might be implicated in the development of neurodegenerative disorders. However, its effect on neuronal cell death has not yet been investigated at gene ex...
  12. Sphingosine-1-phosphate mediates proliferation maintaining the multipotency of human adult bone marrow and adipose tissue-derived stem cells.

    Journal of Molecular Cell Biology 2(4):199 (2010) PMID 20584786

    High renewal and maintenance of multipotency of human adult stem cells (hSCs), are a prerequisite for experimental analysis as well as for potential clinical usages. The most widely used strategy for hSC culture and proliferation is using serum. However, serum is poorly defined and has a conside...
  13. SphK1 regulates proinflammatory responses associated with endotoxin and polymicrobial sepsis.

    Science 328(5983):1290 (2010) PMID 20522778

    During sepsis, activation of phagocytes leads to the overproduction of proinflammatory cytokines, causing systemic inflammation. Despite substantial information regarding the underlying molecular mechanisms that lead to sepsis, several elements in the pathway remain to be elucidated. We found th...
  14. Mast cells express IL-17A in rheumatoid arthritis synovium.

    Journal of Immunology 184(7):3336 (2010) PMID 20200272

    The proinflammatory cytokine IL-17A is considered a crucial player in rheumatoid arthritis (RA) pathogenesis. In experimental models of autoimmune arthritis, it has been suggested that the cellular source of IL-17A is CD4(+) T cells (Th17 cells). However, little is known about the source of IL-1...

    Journal of Immunology 184(5):2620 (2010) PMID 20139274

    Rheumatoid arthritis pathogenesis comprises dysregulation in both innate and adaptive immunity. There is therefore intense interest in the factors that integrate these immunologic pathways in rheumatoid arthritis. In this paper, we report that IL-33, a novel member of the IL-1 family, can exacer...
