Release of secretory immunoglobulin A by submandibular gland via β adrenergic receptor stimulation.

Arch Oral Biol

September 2021

Laboratory of Molecular Biology, Department of Veterinary Medicine, College of Bioresource Sciences, Nihon University, 1866 Kameino, Fujisawa, Kanagawa, 252-0880, Japan. Electronic address:

Objective: Secretory immunoglobulin A (sIgA) is important for mucosal immunity due to the inhibition of pathogen infection. The submandibular gland is known to secrete more sIgA than the parotid and sublingual glands. In this study, we focused on the relationship between the secretion of accumulated intracellular sIgA and β-adrenergic receptor stimulation, and clarified the autonomic regulatory mechanism of sIgA secretion in submandibular gland cells using dispersed gland cells.

A case control study was conducted to estimate the prevalence of feather-damaging behavior and evaluate the correlation with risk factors among pet psittacine birds in Japan. Although feather-damaging behavior among pet parrots is frequently observed in Japan, its prevalence and potential risk factors have not been investigated. Therefore, we conducted an online questionnaire survey on parrot owners throughout Japan to examine regional differences in feather-damaging behavior and associated risk factors.

Salivary fluid secretion involves an intricate choreography of membrane transporters to result in the trans-epithelial movement of NaCl and water into the acinus lumen. Current models are largely based on experimental observations in enzymatically isolated cells where the Ca signal invariably propagates globally and thus appears ideally suited to activate spatially separated Cl and K channels, present on the apical and basolateral plasma membrane, respectively. We monitored Ca signals and salivary secretion in live mice expressing GCamp6F, following stimulation of the nerves innervating the submandibular gland.

The Japanese Pharmacopoeia (JP) is an official normative publication that is referred to, for establishing the authenticity and properties and maintaining the quality of pharmaceutics in Japan. Partial amendments are periodically made to these guidelines to keep up with the progress of science and technology, and the international harmonization is revised every 5 years. Thus, "Internationalization of the JP" is one of the more important issues to address for the revision of the JP.

Identification of the causative gene of a transparent phenotype of juvenile red sea bream Pagrus major.

Heredity (Edinb)

August 2021

Department of Marine Science and Resources, College of Bioresource Sciences, Nihon University, Fujisawa, Kanagawa, Japan.

Deformities in cultured fish species may be genetic, and identifying causative genes is essential to expand production and maintain farmed animal welfare. We previously reported a genetic deformity in juvenile red sea bream, designated a transparent phenotype. To identify its causative gene, we conducted genome-wide linkage analysis and identified two single nucleotide polymorphisms (SNP) located on LG23 directly linked to the transparent phenotype.

Article Synopsis
  • The study investigated the expression of surfactant proteins A and D (SP-A and SP-D) in the uterine and placental tissues of 13 pregnant mares using specific antibodies.
  • Strong positive reactions for both proteins were found in the placenta's trophoblasts during the later stages of gestation, while weaker reactions were noted in the uterine epithelial cells.
  • This research is the first to document changes in SP-A and SP-D expression levels in mare endometrium throughout pregnancy, with increased levels observed after the second trimester.

Liver X receptors (LXRs) belong to the nuclear hormone receptor superfamily and function as ligand-dependent transcription factors that regulate cholesterol homeostasis, lipid homeostasis, and immune responses. LXR antagonists are promising treatments for hypercholesterolemia and diabetes. However, effective LXR antagonists and inhibitors are yet to be developed.

We isolated ascomycetous yeasts including Candida species, that originally belonged to the genus Candida, from bulk milk in the Aichi area of Japan, and determined the minimum inhibitory concentrations (MICs) of antifungal drugs on these isolates by conducting E-tests. We isolated 7 human pathogenic species (14 isolates) from 14 bulk milk samples: 5 Candida species of yeasts, and 2 Candida-related species. Two isolates of C.

We previously reported the non-viral derivation of transgene-free induced pluripotent stem cells (iPSCs) from somatic fibroblasts of a female beagle dog using an optimized induction medium and integration-free episomal vectors. Here, we report novel derivation of a male canine iPSC line OF35Y-iPS, which showed standard characteristics of pluripotency such as a strong gene expression profile of pluripotency markers, differentiation potential into all three germ layers, and normal karyotype (78XY). Furthermore, we demonstrated targeted integration of 2A-EGFP into the canine NANOS3 locus.

Background/aim: Copper metabolism MURR1 domain-containing 5 (COMMD5) is mainly expressed in renal tubules (RTs), where it facilitates re-differentiation of injured RTs. We reported that COMMD5 regulates the expression of epidermal growth factor receptor by participating in its endocytic membrane trafficking, thus inhibiting tumor growth. Here we aimed to determine the role of COMMD5 in malignant phenotypes of renal cell carcinoma (RCC).

Inflammasomes play a pivotal role in gastrointestinal homeostasis and inflammation. However, it remains elusive whether the nucleotide-binding oligomerization domain-like receptor (NLR) family inflammasomes, such as NLR family pyrin domain-containing (NLRP) 3, NLRP6, and NLRP12, are involved in the pathogenesis of canine chronic enteropathy (CE), which includes antibiotic-responsive enteropathy (ARE), food-responsive enteropathy (FRE), immunosuppressant-responsive enteropathy (IRE), and non-responsive enteropathy (NRE). Thus, we measured mRNA expression of NLRP3, NLRP6, and NLRP12 in the intestinal mucosa of 35 dogs with CE (ARE, four dogs; FRE, 11 dogs; IRE and NRE, 20 dogs) and seven healthy dogs.

Department of Veterinary Medicine, College of Bioresource Sciences, Nihon University, 1866 Kameino, Fujisawa, Kanagawa, 252-0880, Japan. Electronic address:

Canine chronic enteropathy (CE) is a group of immunogenetic disorders of unclear etiology characterized by chronic or recurrent gastrointestinal signs and inflammation. Diagnosis of CE subtypes by treatment response is a lengthy and challenging process, particularly in refractory cases of the disease. Given known association of dog leukocyte antigen (DLA) class II genotype and various immunogenetic disorders between and across breeds, this study was designed to examine the potential of determining susceptibility to refractory CE through identification of risk and protective genotypes in French bulldogs and miniature dachshunds-two popular dog breeds in Japan.

Inhibition of programmed death-ligand 1 (PD-L1) in cancer cells provides a reasonable avenue to prevent cancer progression. Although oleate is known to exert anti-cancer effects, its PD-L1 inhibitory effects have not been proven. This study investigated the effects of oleic acid and an oleic acid metabolite, oleoylethanolamide (OEA), on PD-L1 expression and biomarkers of tumorigenesis in several cancer cell lines, namely A549, HuH-7, MCF-7, DLD-1, and LoVo cells.
