In a recent study published in Nature,York and coworkers identified the immunometabolic regulation of mono-unsaturated fatty acid(MUfA)pools and the subsequent increase in sphingolipid biosynthesis in TLR2-activated macrophages as an important link between impaired IL-10 signaling and the development of intestinal inflammation.1 Thus,targeted interference with the newly identified IL-10/MUfA/sphingolipid axis appears as a promising strategy to restore immunometabolic homeostasis in the intestine of patients with inflammatory bowel diseases(IBD).

Dear Editor,This letter proposes a parameter-free multiple kernel clustering(MKC)method by using shifted Laplacian *** MKC can effectively cluster nonlinear data,but it faces two main challenges:1)As an unsupervised method,it is up against parameter problems which makes the parameters intractable to tune and is unfeasible in real-life applications;2)Only considers the clustering information,but ignores the interference of noise within Laplacian.

Magnesium rechargeable batteries（MRBs） present opportunities for grid-scale energy storage applications as a complement to Li-ion batteries（LIBS）. The major challenges are the low reversible capacity, inferior cycling stability and unsatisfactory energy densities. Na3VCr0.5fe0.5（PO4）3with a well-defined NASIONtype structure is used as cathode in Mg cell. Two-electrons reaction（～116 m Ah/g）, 1.5 V average voltage and 65% of capacity retention over 100 cycles are accomplished. Mg is inserted by a biphasic reaction with the participation of V3+/V4+/V5+redox couples in the electrochemical reaction while the non-active redox couples such as Cr3+/Cr4+and fe2+/fe3+served as stabilizer to buffer the volume variation. A thermal stability up to ～412 °C is also exhibited. Therefore, incorporating a mixture of three transition metal（V/Cr/fe） in this type of structures will broaden new perspectives for realizing high performance cathodes for MRBs.

The etiological factors contributing to depression and other neuropsychiatric disorders are largely undefined. Endoplasmic reticulum stress pathways and autophagy are well-defined mechanisms that play critical functions in recognizing and resolving cellular stress and are possible targets for the pathophysiology and treatment of psychiatric and neurologic illnesses. An increasing number of studies indicate the involvement of endoplasmic reticulum stress and autophagy in the control of neuroinflammation, a contributing factor to multiple neuropsychiatric illnesses. Initial inflammatory triggers induce endoplasmic reticulum stress, leading to neuroinflammatory responses. Subsequently, induction of autophagy by neurosteroids and other signaling pathways that converge on autophagy induction are thought to participate in resolving neuroinflammation. The aim of this review is to summarize our current understanding of the molecular mechanisms governing the induction of endoplasmic reticulum stress, autophagy, and neuroinflammation in the central nervous system. Studies focused on innate immune factors, including neurosteroids with anti-inflammatory roles will be reviewed. In the context of depression, animal models that led to our current understanding of molecular mechanisms underlying depression will be highlighted, including the roles of sigma 1 receptors and pharmacological agents that dampen endoplasmic reticulum stress and associated neuroinflammation.
