Mechanoreceptor Piezo1 channel-mediated interleukin expression in conjunctival epithelial cells: Linking mechanical stress to ocular inflammation.

Purpose: Mechanical stress on the ocular surface, such as from eye-rubbing, has been reported to lead to inflammation and various ocular conditions. We hypothesized that the mechanosensitive Piezo1 channel in the conjunctival epithelium contributes to the inflammatory response at the ocular surface after receiving mechanical stimuli.

Methods: Human conjunctival epithelial cells (HConjECs) were treated with Yoda1, a Piezo1-specific agonist, and various allergens to measure cytokine expression levels using qRT-PCR.

A Case of Chronic Active Antibody-Mediated Rejection Caused by a Pre-Existing Anti-DQ Donor-Specific Antibody in a Systemic Lupus Erythematosus Recipient Without History of Sensitization: A Case Report.

Background: Systemic lupus erythematosus (SLE) is reported to produce anti-HLA antibodies. We report a case of chronic active antibody-mediated rejection caused by pre-existing donor-specific antibody (DSA) in a patient with SLE without a history of sensitization.

Case Report: The case was a 29-year-old man with end-stage renal disease due to lupus nephritis.

Shoseiryuto Ameliorated TDI-Induced Allergic Rhinitis by Suppressing IL-33 Release from Nasal Epithelial Cells.

Toluene diisocyanate (TDI) is a major cause of occupational asthma and rhinitis. Shoseiryuto (SST) is one of the traditional herbal medicines (Kampo medicine) and has long been used as a natural medicine for allergic diseases such as allergic rhinitis (AR) and asthma. Recent studies have shown that the expression and release of IL-33, which regulates the T2 cytokine response in epithelial cells, is an important step in developing the inflammatory response of the nasal mucosa.

The Japanese Herbal Medicine Yokukansan Exerted Antioxidant and Analgesic Effects in an Experimental Rat Model of Hunner-Type Interstitial Cystitis.

: The Japanese herbal medicine Yokukansan (YKS) has analgesic properties and is used for various pain disorders. The purpose of the present study was to investigate the effects of YKS in Hunner-type interstitial cystitis (HIC) using an experimental rat model of HIC and to explore its antioxidant activity and role as the underlying mechanism of action. : The antioxidant capacity of YKS was evaluated by determining its hydroxyl radical (·OH) scavenging capacity using electron spin resonance (ESR).

Kampo Formulae for the Treatment of Neuropathic Pain ∼ Especially the Mechanism of Action of ∼.

Kampo medicine has been practiced as traditional medicine (TM) in Japan. Kampo medicine uses Kampo formulae that are composed of multiple crude drugs to make Kampo formulae. In Japan, Kampo formulae are commonly used instead of or combined with Western medicines.
