Targeting TMEM16A ion channels suppresses airway hyperreactivity, inflammation, and remodeling in an experimental Guinea pig asthma model.

Asthma is a chronic inflammatory disease characterized by airway hyperresponsiveness, inflammation, and remodeling. Calcium (Ca)-activated chloride (Cl) channels, such as TMEM16A, are inferred to be involved in asthma. Therefore, the present study investigated the therapeutic potential of TMEM16A inhibition in a guinea pig model of ovalbumin (OVA)-induced allergic asthma.

Exploring cytokine dynamics in tuberculosis: A comparative analysis of patients and controls with insights from three-week antituberculosis intervention.

Despite developing new diagnostics, drugs, and vaccines, treating tuberculosis (TB) remains challenging. Monitoring inflammatory markers can contribute to more precise diagnostics of TB, identifying its active and latent forms, or monitoring its treatment success. We assessed alterations in plasma levels of 48 cytokines in 20 patients (17 males) with active pulmonary TB compared to age-matched healthy controls (n = 18).

Immune analysis of urine and plasma samples from patients with clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is the third most common type of urological malignancy worldwide, and it is associated with a silent progression and late manifestation. Patients with a metastatic form of ccRCC have a poor prognosis; however, when the disease is diagnosed early, it is largely curable. Currently, there are no biomarkers available in clinical practice for ccRCC.

Analysis of HIF-1α expression and genetic polymorphisms in human clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is mostly diagnosed incidentally and has relatively high recurrence rates. Alterations in VHL/HIF and mTOR pathways are commonly present in ccRCC. The present study attempted to identify potential diagnostic markers at the biochemical and molecular level.

Immunobiochemical profile of clear cell renal cell carcinoma (ccRCC): A preliminary study.

Clear cell renal cell carcinoma (ccRCC) is the most common variant of RCC. It is an aggressive disease with an unfavorable prognosis. The rich immune infiltrates present in the tumor microenvironment (TME) of ccRCC produce various signaling molecules, especially cytokines, which primarily activate the Jak/STAT pathway and significantly influence tumor pathogenesis.

Dysfunctional mucociliary clearance in asthma and airway remodeling - New insights into an old topic.

Bronchial asthma is a heterogeneous respiratory condition characterized by chronic airway inflammation, airway hyperresponsiveness and airway structural changes (known as remodeling). The clinical symptoms can be evoked by (non)specific triggers, and their intensity varies over time. In the past, treatment was mainly focusing on symptoms' alleviation; in contrast modern treatment strategies target the underlying inflammation, even during asymptomatic periods.

Pharmacodynamic evaluation of dihydroxyflavone derivate chrysin in a guinea pig model of allergic asthma.

Objective: This experimental study evaluated the anti-asthmatic capacity of the dihydroxyflavone chrysin in the settings of ovalbumin (OVA)-induced allergic inflammation.

Methods: The parameters that were used to assess the anti-asthmatic activity of chrysin included the specific airway resistance to histamine, the sensitivity to a chemically induced cough and the activity of chrysin on the ciliary beat frequency (CBF) of the respiratory epithelium. The anti-inflammatory potential was confirmed by the measurement of cytokine concentrations Th2 (IL-4, IL-5 and IL-13), Th1 (Granulocyte-macrophage colony-stimulating factor [GM-CSF], INF-γ and IL-12), leucocyte count in the bronchoalveolar lavage fluid (BALF) and growth factor TBF-β1 in lung homogenate.

Effects of Inhalation of STIM-Orai Antagonist SKF 96365 on Ovalbumin-Induced Airway Remodeling in Guinea Pigs.

Airway remodeling (AR) consists of wall thickening and hyperreactivity. STIM (stromal interaction molecule) and Orai protein pathways mediate extracellular Ca signals involved in AR. This study aims to define the effects on AR of the STIM-Orai antagonist SKF 96365 given by inhalation in three increasing doses in ovalbumin-induced AR.

The anti-asthmatic potential of flavonol kaempferol in an experimental model of allergic airway inflammation.

Flavonol kaempferol possesses a broad spectrum of potent pharmacological activities that seem to be effective in the modulation of allergic respiratory diseases. In our study, an experimental animal model of ovalbumin (OVA)-induced allergic airway inflammation in guinea pigs was used to determine the anti-asthmatic potential of kaempferol. The parameters of specific airway resistance (sRaw) and cough reflex response were evaluated in vivo.

Structural characterization and anti-asthmatic effect of α-l-arabino(4-O-methyl-α-d-glucurono)-β-d-xylan from the roots of Rudbeckia fulgida.

Many native plant biopolymers or derivatives thereof have interesting biological effects and therefore the search for additional biological activities is important to map their overall effects. A low molecular weight (M = 7600 g/mol) hemicellulose polymer α-L-arabino(4-O-methyl-α-D-glucurono)-β-D-xylan (AGX) was isolated from the crushed roots of the Rudbeckia fulgida medicinal plant by alkaline extractions and anion-exchange chromatography. Analysis of neutral sugars revealed a predominance of xylose (82.

Respiratory Cilia as a Therapeutic Target of Phosphodiesterase Inhibitors.

Mucociliary clearance is an essential airway defense mechanism dependent predominantly on the proper ciliary function and mucus rheology. The crucial role of cilia is evident in `a variety of respiratory diseases, as the ciliary dysfunction is associated with a progressive decline in lung function over time. The activity of cilia is under supervision of multiple physiological regulators, including second messengers.

Negative impact of anesthesia with midazolam, sufentanil, and propofol used in pediatric flexible bronchoscopy on the tracheal ciliary beat frequency in guinea pigs.

There is no direct evidence for the exact cilia-inhibitory effects of opioids, which are generally used to achieve general anesthesia in combination with other anesthetic drugs. These are the reasons, why we analysed direct concentration-dependent or systemic effects of anesthetics (propofol, sufentanil, and midazolam) at a recommended doses administered individually or simultaneously on the tracheal ciliary beat frequency (CBF) in in vitro experimental conditions. Brush biopsy technique was used to remove the tracheal epithelia of guinea pigs for microscopy evaluation of ciliary beating monitored by high-speed video camera and analysed by Ciliary Analysis software.
