Liver hepatocytes (Hep) are known to be central players during the inflammatory response to systemic infection. Interestingly, the protein tyrosine phosphatases (PTP) SHP-1, has been recognized as a major regulator of inflammation; however their implication in the control of Hep-mediated inflammatory response is still unknown. To study its implication in the regulation of the Hep-mediated inflammatory response during endotoxemia, Cre-Lox mice with a Hep-specific Ptpn6 deletion (Ptpn6 (H-KO) ) were injected with LPS...

Programmed cell death ligand-1 (PD-L1) is typically produced by cancer cells and suppresses immunity through the receptor PD-1 expressed on T cells. However, the role of PD-L1 and PD-1 in regulating pain and neuronal function is unclear. Here we report that both melanoma and normal neural tissues including dorsal root ganglion (DRG) produce PD-L1 that can potently inhibit acute and chronic pain. Intraplantar injection of PD-L1 evoked analgesia in naive mice via PD-1, whereas PD-L1 neutralization or PD-1 blockade induced mechanical allodynia...

Shp-1 (Src homology region 2 domain-containing protein tyrosine phosphatase-1) is a phosphatase that is highly expressed in hematopoietic and epithelial cells. Whereas its function is largely characterized in hematopoietic cells, its role in epithelial cells, such as intestinal epithelial cells (IECs), is not well known. Here, we generated mice with an IEC-specific deletion of Shp-1 (Src homology region 2 domain-containing phosphatase-1; Shp-1(IEC-KO)). We showed that the loss of epithelial Shp-1 leads to an intestinalomegaly that is associated with an increase in epithelial cell proliferation and size...

It is well known that glucagon-like peptide 1 (GLP-1) has antidiabetic action. It has 2 distinct functions, an insulinotropic effect dependent on GLP-1 receptor (GLP-1R) and an insulinomimetic effect independent of GLP-1R. However, use of GLP-1 in vivo is limited by its short half-life. Therefore, our lab designed PGLP-1, a novel 2-function candidate peptide as a potential substitute. Using a streptozotocin-induced hyperglycemic mouse model, we demonstrated in vitro and in vivo that PGLP-1 had insulinotropic actions dependent on GLP-1R and insulinomimetic functions independent of GLP-1R...

Objective Environmental and climatic changes have been occurring throughout the past 20 years in Japan. Correspondingly, the antigens that cause hypersensitivity pneumonitis might be changing. In an epidemiological survey of Japan in the 1980s, summer-type hypersensitivity pneumonitis (SHP) accounted for 74.4% of the cases of hypersensitivity pneumonitis. The epidemiological characteristics of this disease have not been reported since then. We investigated the annual changes in the number of cases of SHP and the factors affecting the results...

Periodontitis is one of the most common inflammatory diseases, with a prevalence of 11% worldwide for the severe forms and an estimated heritability of 50%. The disease is characterized by destruction of the alveolar bone due to an aberrant host inflammatory response to a dysbiotic oral microbiome. Previous genome-wide association studies (GWAS) have reported several suggestive susceptibility loci. Here, we conducted a GWAS using a German and Dutch case-control sample of aggressive periodontitis (AgP, 896 cases, 7,104 controls), a rare but highly severe and early-onset form of periodontitis, validated the associations in a German sample of severe forms of the more moderate phenotype chronic periodontitis (CP) (993 cases, 1,419 controls)...

Lysosome-mediated autophagy is essential for cellular survival and homeostasis upon nutrient deprivation, but is repressed after feeding. Despite the emerging importance of transcriptional regulation of autophagy by nutrient-sensing factors, the role for epigenetic control is largely unexplored. Here, we show that Small Heterodimer Partner (SHP) mediates postprandial epigenetic repression of hepatic autophagy by recruiting histone demethylase LSD1 in response to a late fed-state hormone, FGF19 (hFGF19, mFGF15)...

Medical conditions accompanying obesity often require drug therapy, but whether and how obesity alters the expression of drug-metabolizing enzymes and thus drug pharmacokinetics is poorly defined. Previous studies have shown that high fat diet (HFD) feeding and subsequent obesity in mice lead to altered expression of transcriptional regulators for cytochrome P450 (CYP) 2D6, including hepatocyte nuclear factor 4α (HNF4α, a transcriptional activator of CYP2D6) and small heterodimer partner (SHP, a transcriptional repressor of CYP2D6)...

Hypoxia promotes vascularization by stabilization and activation of the hypoxia inducible factor 1α (HIF-1α), which constitutes a target for angiogenic gene therapy. However, gene therapy is hampered by low gene delivery efficiency and non-specific side effects. Here, we developed a gene transfer technique based on magnetic targeting of magnetic nanoparticle-lentivirus (MNP-LV) complexes allowing site-directed gene delivery to individual wounds in the dorsal skin of mice. Using this technique, we were able to control HIF-1α dependent wound healing angiogenesis in vivo via site-specific modulation of the tyrosine phosphatase activity of SHP-2...
