Activation-induced cytidine deaminase (AID) and apolipoprotein B mRNA-editing catalytic polypeptide 3 (A3) family are cytidine deaminases that play critical roles in B-cell maturation, antiviral immunity and carcinogenesis. Adenoids and palatine tonsils are secondary lymphoid immune organs, in which AID and A3s are thought to have several physiological or pathological roles. However, the expression of AID or A3s in these organs has not been investigated. Therefore, we investigated the expression profiles of AID and A3s, using 67 samples of adenoids and palatine tonsils from patients, with reverse transcription quantitative polymerase chain reaction (RT-qPCR) and immunohistochemical analyses...

BACKGROUND: Many epidemiological studies of Guillain-Barré syndrome (GBS) and Fisher syndrome (FS) have been conducted in Europe and America. In contrast, epidemiological studies are rare in Asia where the GBS subtypes differ from those in Western countries. This study was undertaken to clarify the incidence of GBS and FS in a local area in Japan as well as their seasonal trends. METHODS: Seventy-one GBS and 37 FS patients were recorded from 2006 to 2015 in an area of approximately 1...

Previous immunological studies in atomic bomb survivors have suggested that radiation exposure leads to long-lasting changes, similar to immunological aging observed in T-cell-adaptive immunity. However, to our knowledge, late effects of radiation on dendritic cells (DCs), the key coordinators for activation and differentiation of T cells, have not yet been investigated in humans. In the current study, we hypothesized that numerical and functional decreases would be observed in relationship to radiation dose in circulating conventional DCs (cDCs) and plasmacytoid DCs (pDCs) among 229 Japanese A-bomb survivors...

Social dominance, in which an individual asserts control over others or benefits most after social conflict, has an influence on social behaviour. However, the mechanisms mediating social dominance remain unclear. Social dominance within social groups determines the distribution of rewards such as food and access to mating partners, which can act as reinforcers. In this study, we used the water competition test to determine whether mice were dominant or subordinate. We have previously reported that mice heterozygous for a missense mutation in Grin1 (Grin1(Rgsc174) ) showed altered social behaviour, with increased locomotor activity, novelty-seeking and anxiety...

PURPOSE: Pediatric patients with intestinal failure need long-term parenteral nutrition (PN), but this nutritional support causes liver dysfunction, such as intestinal failure-associated liver disease (IFALD). Several studies have shown that the lipid emulsion produced by soybean oil (SO) is associated with the occurrence of IFALD. In this study, we evaluated the effect of SO and fish oil (FO) lipid emulsion on hepatic steatosis. METHODS: Sprague-Dawley rats underwent jugular vein catheterization and were divided into three groups: sham operation with normal chow (Sham group), 80% small bowel resection (80% SBR) + TPN with SO lipid emulsion (SO group), and 80% SBR + TPN with FO lipid emulsion (FO group)...

DJ-1 (also known as PARK7) has been identified as a causal gene for hereditary recessive Parkinson's disease (PD). Consequently, the full elucidation of DJ-1 function will help decipher the molecular mechanisms underlying PD pathogenesis. However, because various, and sometimes inconsistent, roles for DJ-1 have been reported, the molecular function of DJ-1 remains controversial. Recently, a number of papers have suggested that DJ-1 family proteins are involved in aldehyde detoxification. We found that DJ-1 indeed converts methylglyoxal (pyruvaldehyde)-adducted glutathione (GSH) to intact GSH and lactate...

BACKGROUND: Although Nucleos(t)ide analogue therapy is thought to suppress chronic hepatitis B(CHB) via regulation of inflammatory cytokines/chemokines, the mechanism is still unclear. In this study, serum cytokine/chemokine levels were measured in CHB patients treated with entecavir, and the association with antiviral response was analyzed. METHODS: Seventy-eight Japanese patients with CHB were enrolled, and serum cytokine/chemokine levels were measured at baseline and at 12, 24, and 48 weeks of entecavir treatment using the MULTIPLEX kit...

The molecular conformation of a bisbinaphthyldurene (BBD) molecule is manipulated using a low-temperature ultrahigh-vacuum scanning tunneling microscope (LT-UHV STM) on an Au(111) surface. BBD has two binaphthyl groups at both ends connected to a central durene leading to anti/syn/flat conformers. In solution, dynamic nuclear magnetic resonance indicated the fast interexchange between the anti and syn conformers as confirmed by density functional theory calculations. After deposition in a submonolayer on an Au(111) surface, only the syn conformers were observed forming small islands of self-assembled syn dimers...

There is growing evidence to suggest that the prevailing physical microenvironment and mechanical stress regulate cellular functions, including adhesion, proliferation, and differentiation. Moreover, the physical microenvironment determines the stem-cell lineage depending on stiffness of the substrate relative to biological tissues as well as the stress relaxation properties of the viscoelastic substrates used for cell culture. However, there is little known regarding the biological effects of a fluid substrate, where viscoelastic stress is essentially absent...

The cornea serves as a barrier to protect the eye against external insults including microbial pathogens and antigens. Bacterial infection of the cornea often results in corneal melting and scarring that can lead to severe visual impairment. Not only live bacteria but also their components such as lipopolysaccharide (LPS) of Gram-negative bacteria contribute to the development of inflammation and subsequent corneal damage in infectious keratitis. We describe the important role played by corneal stromal fibroblasts (activated keratocytes) as sentinel cells, immune modulators, and effector cells in infectious keratitis...
