Ethnopharmacological relevance: Immunoglobulin A (IgA) secretion and alpha-defensins play a role in the innate immune system to protect against infection. Ganoderma lucidum (W.Curt.: Fr.) P. Karst. (Reishi) is a well-known mushroom in traditional Chinese medicine. This study aimed to determine the effects of Reishi on IgA secretion from Peyer's patch (PP) cells and alpha-defensin-5 (RD-5) and RD-6 expression in the rat small intestine. Materials and methods: The rats received an oral injection of 0.5-5 mg/kg of Reishi powder (1 mL/kg) by sonde. All animals were euthanized 24 h after Reishi administration. We examined RD-5, RD-6, and Toll-like receptor (TLR) 4 mRNA levels in the jejunum, ileum, and in Peyer's patches (PP) through quantitative real-time PCR analysis. IgA secretion from PP was measured through enzyme-linked immunosorbent assay of the supernatant after primary culture. Results: Reishi increased IgA secretion in the presence of lipopolysaccharide (LPS) and increased TLR4 mRNA levels, but had no effect on the viability of PP cells. Moreover, Reishi increased RD-5, RD-6, and TLR4 mRNA levels significantly in the ileum in a concentration-dependent manner. Conclusions: Reishi can induce IgA secretion and increase the mRNA levels of RD-5 and RD-6 in the rat small intestine, through a TLR4-dependent pathway. The present results indicate that Reishi might reduce the risk of intestinal infection.

In vitro and in vivo evaluation of organic anion-transporting polypeptide 2B1-mediated pharmacokinetic interactions by apple polyphenols

Yuka Takahashi, Katsuya Narumi, Takanobu Nadai, Hinata Ueda, Taiki Yamamura, Ayako Furugen, Masaki Kobayashi

Summary: Apple polyphenols such as phloretin and phloridzin inhibit the transport of substrate drugs mediated by OATP2B1 in vitro. Specifically, phloretin can decrease the uptake of rosuvastatin in rats, suggesting a potential role in altering drug absorption. However, the systemic exposure of rosuvastatin was not significantly affected by phloretin in rats.

Summary: Third-generation oral cephalosporins, especially cefcapene-pivoxil, have been commonly used in the Japanese dental field for prophylactic antibiotics. However, after the implementation of clinical guidelines, the usage of amoxicillin has increased while the usage of cefcapene-pivoxil has decreased. This antibiotic switch is cost-effective and does not significantly affect the incidence rates of infectious complications.

Atorvastatin Exerts More Selective Inhibitory Effects on hMCT2 than on hMCT1 and hMCT4

Atsushi Yamaguchi, Yuto Mukai, Tomoya Sakuma, Ayako Furugen, Katsuya Narumi, Masaki Kobayashi

Summary: This study found that statins can inhibit the transport activities of hMCT1, hMCT2, and hMCT4, with atorvastatin showing potent isoform-selective inhibition of hMCT2. Docking simulation revealed that atorvastatin could interact with a specific site, potentially leading to the discovery of more potent hMCT2-selective inhibitors. These findings are important for understanding the inhibitory mechanism of statins against hMCT1, hMCT2, and hMCT4, and may contribute to the development of novel anticancer agents.

Summary: Alpha-defensin 5 is secreted by Paneth cells in the small intestine and its decrease in level is a risk factor for inflammatory bowel disease (IBD). P-glycoprotein (P-gp), encoded by ABCB1/MDR1 gene, plays a role in protecting the gastrointestinal barrier and may contribute to IBD. This study found that alpha-defensin 5 regulates P-gp expression and function by increasing TNF-alpha expression in Caco-2 cells.
