Targeting enteric glial CRF-R1/Cx43 attenuates stress-induced accelerated colonic motility.

J Pharmacol Sci

March 2025

Department of Anesthesiology & Center for Brain Science, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, 710061, Shaanxi, China. Electronic address:

Stress triggers disorders in accelerated peristalsis, with corticotropin releasing factor receptor 1 (CRF-R1) playing a pivotal role. Enteric glia cells (EGCs) and glial Cx43 are known to influence gastrointestinal motility, yet their involvement in colonic motor responses to stress remains unclear. Using immunofluorescence and single-cell RNA sequencing data, we identified CRF-R1 expression in EGCs.

Introduction: Neonatal anesthesia-related neurological impairments are of significant concern, closely linked to oligodendrocyte dysfunction. However, there is a notable temporal discrepancy between the sustained development of oligodendrocytes (myelination) and the short-term vulnerability to anesthesia exposures.

Objectives: Given the significant rise in iron demand by oligodendrocytes during neonatal period, our objective was to clarify the potential roles and underlying mechanisms of iron homeostasis, particularly focusing on transferrin receptor 1 (TfR1), in governing the transient susceptibility to anesthesia.

State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, National Clinical Research Center for Oral Diseases, Shaanxi International Joint Research Center for Oral Diseases, Department of Periodontology, School of Stomatology, The Fourth Military Medical University, Xi'an, China.

Background: This study focused on whether the effectiveness of nonsurgical periodontal therapy (NSPT) on second molars (M2s) varies with the status of adjacent nonimpacted third molars (N-M3s).

Methods: In this retrospective cohort study, 776 regions from 268 patients were evaluated. Based on the adjacent N-M3 status, quadrants with M2s were categorized into three groups: N-M3 group (present N-M3), A-M3 group (absent M3), and R-M3 group (removed N-M3).

Nuclear factor of activated T-cells 5 (NFAT5) is recognized as an oncogene in a variety of tumors. However, the role of NFAT5 in cervical cancer (CC) cell phenotypic alterations remains to be elucidated. Here, we demonstrated that NFAT5 expression was elevated in CC samples and cells using quantitative real-time reverse transcription PCR, Western blot analysis, and immunohistochemistry assays, and high NFAT5 expression showed a poor prognosis.

State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, National Clinical Research Center for Oral Diseases, Shaanxi International Joint Research Center for Oral Disease, Center for Tissue Engineering, School of Stomatology, The Fourth Military Medical University, Xi'an, 710032, Shaanxi, China.

Healthy aging is a common goal for humanity and society, and one key to achieving it is the rejuvenation of senescent resident stem cells and empowerment of aging organ regeneration. However, the mechanistic understandings of stem cell senescence and the potential strategies to counteract it remain elusive. Here, we reveal that the aging bone microenvironment impairs the Golgi apparatus thus diminishing mesenchymal stem cell (MSC) function and regeneration.

Determining the neural bases of basic linguistic composition is central to research on the cognitive neuroscience of language. The left anterior temporal lobe (LATL) is widely reported during linguistic composition of visual stimuli in magnetoencephalography (MEG) studies. However, this effect is less reported during the linguistic composition of auditory stimuli in intracranial electroencephalography (iEEG) studies.

Background: Entity-level pathologic structures with independent structures and functions are at a mesoscopic scale between the cell-level and slide-level, containing limited structures thus providing fewer instances for multiple instance learning. This restricts the perception of local pathologic features and their relationships, causing semantic ambiguity and inefficiency of entity embedding.

Method: This study proposes a novel entity-level multiple instance learning.

Microglia TRPC1 SUMOylation drives neuroinflammation after stroke by modulating NLRP3 activity via increasing TRPC1 interaction with ARRB2.

Health Management Center, Second Affiliated Hospital, Fourth Military Medical University, Xi'an 710038, China; Department of Neurology, Second Affiliated Hospital, Fourth Military Medical University, Xi'an 710038, China. Electronic address:

Microglial canonical transient receptor potential channel 1 (TRPC1) has been proposed to influence neuroinflammation after cerebral ischemia and reperfusion injury (CIRI), however, the underlying mechanism remains poorly understood. This study demonstrates that TRPC1 is modified by small ubiquitin-related modifier (SUMO)ylation. Our findings suggest a notable increase in microglial TRPC1 SUMOylation within both the middle cerebral artery occlusion reperfusion (MCAO/R) model and the in vitro oxygen-glucose deprivation/regeneration model.

Glioblastoma (GBM) is a primary brain tumor known for its high levels of aggressiveness and resistance to current treatments such as radiotherapy and chemotherapy. As a result, there is a pressing need for innovative therapeutic approaches to combat GBM. Thus, we have developed an engineered multifunctional extracellular vesicle (EV) delivery system that offers an "all-in-one" strategy for GBM therapy.

Objective: To assess the efficacy/safety of ivarmacitinib, a selective Janus kinase (JAK) 1 inhibitor, in patients with moderate-to-severe active rheumatoid arthritis (RA) who had an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs).

Methods: Patients were randomised (1:1:1) to receive either placebo (n=188), ivarmacitinib 4 mg (n=189) or ivarmacitinib 8 mg (n=189) once daily, with background csDMARDs allowed. After 24 weeks, patients on placebo switched to ivarmacitinib 4 mg for an additional 28 weeks, while those on ivarmacitinib continued their initial dosage.

Background: The Ebola epidemic has persisted in Africa since it was firstly identified in 1976. However, few studies have focused on spatiotemporally assessing the ecological adaptability of this virus and the influence of multiple factors on outbreaks. This study quantitatively explores the ecological adaptability of Ebola virus and its response to different potential natural and anthropogenic factors from a spatiotemporal perspective.

Airway smooth muscle (ASM) dysfunction is a key factor in the narrowing of airways in asthma patients, characterized by excessive secretion of inflammatory factors, increased mass, and amplified contractile responses. These pathological features are instrumental in the propagation of airway inflammation, structural remodeling, and the escalation of airway hyperresponsiveness (AHR), which are also principal factors underlying the limitations of current therapeutic strategies. In asthmatic ASM, an imbalance between oxidant production and antioxidant defenses culminates in oxidative stress, which is involved in the excessive secretion of inflammatory factors, increased mass, and amplified contractile responses of ASM, and is a critical etiological factor implicated in the dysregulation of ASM function.

Perioperative neurocognitive disorder (PND) is a significant neurological complication in aging perioperative patients that impacts post-operative cognition. PND is currently diagnosed through cognitive function testing, which is limited by its subjectivity and time requirements. Thus, the identification of biomarkers to assess PND onset is a priority to identify at-risk individuals and enable interventions and treatments to patient outcomes.

Itch is a distinct and bothersome sensation closely associated with a strong urge to scratch. Both the parabrachial nucleus (PBN) and the central amygdala (CeA) are responsive to itch stimuli and contain neurons that express tachykinin 1 (Tac1), which are known for their significant involvement in itch-induced scratching at both spinal and supraspinal levels. Significantly, the PBN neurons project their axons to form close connections with the CeA neurons.
