Mycobacteria are intracellular pathogens that can survive within macrophage phagosomes, thereby evading host defense strategies by largely unknown mechanisms. We have identified a WD repeat host protein that was recruited to and actively retained on phagosomes by living, but not dead, mycobacteria. This protein, termed TACO, represents a component of the(More)
Marchiafava-Bignami disease (MBD), a rare complication of chronic alcoholism, is characterized by primary demyelination of the corpus callosum. We report two cases of MBD in which fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted imaging studies revealed symmetrical hyperintense lesions in the cerebral cortex (particularly in the(More)
Mouse coxsackie virus and adenovirus receptor (mCAR), which was isolated from the nerve growth cone-enriched fraction of newborn mouse brains, is a member of immunoglobulin-super family, and functions as a homophilic adhesion molecule. We observed the expression of mCAR in embryos to adult tissues by means of immunohistochemical analysis with a peptide(More)
BACKGROUND A crucial role for CD8(+) cells in induction of crescentic anti-glomerular basement membrane (GBM) glomerulonephritis (GN) in WKY rats was demonstrated in studies showing that depletion of CD8(+) cells completely suppressed glomerular accumulation of monocytes/macrophages (Mo/Mphi), crescent formation and proteinuria. Because these studies did(More)
Intratumoral synthesis of dihydrotestosterone (DHT) from precursors cannot completely explain the castration resistance of prostate cancer. We showed that DHT was intratumorally synthesized from the inactive androgen metabolites 5α-androstane-3α/β,17β-diol (3α/β-diol) in prostate cancer cells via different pathways in a concentration-dependent manner.(More)
Background: Hepatocyte nuclear factor-4α (HNF4α; NR2A1) is an orphan member of the nuclear receptor superfamily involved in various processes that could influence endoderm development, glucose and lipid metabolism. A loss-of-function mutation in human HNF4α causes one form of diabetes mellitus called maturity-onset diabetes of the young type 1 (MODY1) which(More)
Hepatocyte nuclear factor-4α (HNF4α, NR2A1) is a nuclear receptor that has a critical role in hepatocyte differentiation and the maintenance of homeostasis in the adult liver. However, a detailed understanding of native HNF4α in the steady-state remains to be elucidated. Here we report the native HNF4α isoform, phosphorylation status, and complexes in the(More)
Macrophages are important for maintaining intestinal immune homeostasis. Here, we show that PPARβ/δ (peroxisome proliferator-activated receptor β/δ) directly regulates CD300a in macrophages that express the immunoreceptor tyrosine based-inhibitory motif (ITIM)-containing receptor. In mice lacking CD300a, high-fat diet (HFD) causes chronic intestinal(More)
—After the cataclysmic explosion in the Fukushima Daiichi Nuclear Power Station triggered by the Great East Japan Earthquake of March 2011, more than 100,000 citizens living within 20km of the nuclear power station were evacuated. These residents were not allowed to return home for more than a year, until April 2012, when the Japanese government began to(More)
