The Role of the TRPV4 Channel in Intestinal Physiology and Pathology.

J Inflamm Res

November 2024

Department of Metabolism and Endocrinology, The First Affiliated Hospital of University of South China, Hengyang Medical School, University of South China, Hengyang, Hunan, 421001, People's Republic of China.

The transient receptor potential vanilloid 4 channel (TRPV4) is an important member of the TRP superfamily of cation channels. The channel can be activated by different physical and chemical stimuli, such as heat, osmotic, and mechanical stress. It regulates the release of nociceptive peptides (substance P and calcitonin gene-related peptide), and mediates neurogenic inflammation, which indicates the involvement of TRPV4 as a nociceptor.

Article Synopsis
  • Dry eye disease (DED) is becoming more common and is linked to inflammation, which damages the cells on the eye's surface, leading to discomfort and vision problems.
  • The loss of these epithelial cells is under investigation, particularly how programmed cell death (PCD) processes—like pyroptosis, apoptosis, and necroptosis—play a role in eye health and response to stress in DED.
  • The emerging concept of PANoptosis, which combines aspects of different PCD pathways, may provide new insights into the inflammatory mechanisms of DED and suggests potential new approaches for treatment.

Background: This study investigated the factors influencing the prognosis of children with steroid-resistant nephrotic syndrome (SRNS) in patients from the Guangxi region.

Methods: We retrospectively analyzed clinical and pathological data of 279 patients with SRNS from six tertiary hospitals in Guangxi. Clinical data were compared between initial (I-SRNS) and secondary (S-SRNS) steroid resistance subgroups and Cox regression analysis was used to determine risk factors for chronic kidney disease (CKD) and CKD stage 5 (CKD5) in patients with SRNS.

Objective: We established a prospective cohort study to investigate the differences in motor and non-motor symptoms between idiopathic Parkinson's disease (IPD) and Parkinson's disease in carriers of leucine-rich repeat kinase 2 (LRRK2) gene risk variants (LRRK2-PD).

Methods: The study included 1407 individuals with IPD and 649 individuals with LRRK2-PD (comprising 304 with LRRK2-G2385R, 220 with LRRK2-R1628P, and 105 with LRRK2-A419V). Differences in symptoms between LRRK2-PD and IPD were analyzed using LCMM modeling and Cox regression analysis.

Background: Debriefing is the essential element of simulation teaching. Peer-led structured debriefing simulations could be a suitable approach because of the peers' similarity in age and experience to the students. The purpose of this study was to compare the teaching effectiveness of peer-led debriefing versus instructor-led debriefing in high-fidelity simulation scenarios.

Revamping anti-cGAS-STING therapy via an injectable thermo-responsive supramolecular hydrogel for pathological retinal angiogenesis.

Xiamen University affiliated Xiamen Eye Center; Fujian Provincial Key Laboratory of Ophthalmology and Visual Science; Fujian Engineering and Research Center of Eye Regenerative Medicine; Eye Institute of Xiamen University, School of Medicine, Xiamen University, Xiamen 361100, China.

Retinal neovascularization is a leading cause of blindness. While current anti-VEGF drugs effectively inhibit pathological angiogenesis, some patients develop resistance or reduced responsiveness to treatments over time, leading to diminished effectiveness. In this study, we identified high activation of the cGAS-STING signaling pathway, which exacerbated pathological neovascularization and vessel leakage.

Article Synopsis
  • * The research indicates that this viral mimicry is driven by increased expression of specific genes with intronic inverted-repeat Alu elements, rather than the activation of retroelements seen in other therapies.
  • * Additionally, EZH2 inhibition enhances the expression of LINE-1 retrotransposons, which contributes to genomic instability and activates immune signaling pathways, but simultaneously blocking dsRNA and DNA sensing prevents the viral mimicry effect in these tumors.

Drug resistance in tumors constitutes a significant obstacle to tumor therapy. Head and neck squamous cell carcinoma (HNSCC) presents a major challenge due to its deep anatomical location, limited space, and complex structure. These factors complicate surgical procedures and hinder the effectiveness of chemoradiotherapy, leading to poor prognosis and reduced quality of life.
