Detection of Cav1 Calcium Channels in Inflammatory Cells of Asthmatic Children

2016-06-22 19:38:22 | BioPortfolio


Asthma affects about 10% of children and 6% of adults in industrialized countries. Lymphocytes (L) Th2, a T cell population (LT) producing interleukin (IL) -4, 5 and 13 are broadly involved in this pathology in experimental models and in humans. Many studies show that the signaling pathways activated by the commitment of T receiver differ depending LT. The identification of specific signaling pathways links to Th2 offer new therapeutic approaches. Precedent study showed that mouse Th2 selectively expressed related to calcium channels sensitive channels Cav1 voltage, normally found in excitable cells where they are defined as receivers dihydropyridine (DHP).

The goal of the present study is to show the presence of Cav1 channels in inflammatory cells in allergic asthmatics and show overexpression of these channels in the peripheral blood mononuclear cells from asthmatic subjects before and / or after stimulation with the TCR in comparison with controls.

Total IgE and Der p 1 (d1) Specific IgE in Induced Sputum in Patients With Allergic and Non-allergic Asthma

Asthma is a heterogeneous disease, and specifically the phenotype of non-allergic asthma is not yet well defined. Several studies describe this group of patients as having severe asthma, p...

Induced Sputum Study

The primary goals of this study will be to implement innovative processing and detection assays to qualify induced sputum measurements of markers of allergen-induced airway inflammation. ...

Non Invasive Evaluation of Bronchial Inflammation in Infants : a Study of the Sputum Cellularity After Hypertonic Saline Induction

- Background: Infantile asthma is composed of various phenotypes, however the definition is still based on the clinics. Namely, the infants could be classified as transitory, pe...

Utility of Versican and Hyaluronan Measurement in Induced Sputum as Biomarkers of Asthma

The purpose of this study is to determine the role of versican and hyaluronan measurements in induced sputum as biomarkers of asthma. Enroll 10 subjects with mild persistent asthma who ar...

Effectiveness and Safety of Inhaling Hypertonic Saline in Patients With Chronic Obstructive Pulmonary Disease

The use of inhaled hypertonic saline has been extensively documented in asthma, bronchiectasis, cystic fibrosis and COPD as method of bronchial challenge and sputum induction, but studies...

Inflammatory Cytokines and T-Lymphocyte Subsets in Serum and Sputum in Patients with Bronchial Asthma and Chronic Obstructive Pulmonary Disease.

BACKGROUND It can be difficult to distinguish between bronchial asthma and chronic obstructive pulmonary disease (COPD) clinically, although these conditions are associated with different profiles of ...

Effect of inhaled corticosteroids on serum periostin levels in adult patients with mild-moderate asthma.

Periostin is an extracellular matrix protein, and its expression is upregulated in airway epithelial cells in patients with bronchial asthma. Periostin may be a key molecule linked to type 2 T-helper ...

Interleukin-17 Gene Expression and Serum Levels in AsthmaDegenerative Model.

Asthma is one of the most common chronic respiratory diseases. It is associated with significant morbidity and shows an increasing prevalence over time. Accumulating evidence suggests that interleukin...

Serum IgG concentrations in adult patients experiencing virus-induced severe asthma exacerbations.

Patients experiencing severe asthma exacerbations have a poorer quality of life and an increase in morbidity and mortality. Viruses are frequently involved in asthma exacerbations.

Sputum ANCA in Serum ANCA-Negative Eosinophilic Granulomatosis with Polyangiitis (eGPA).

Eosinophilic granulomatosis with polyangiitis (eGPA) is a small-vessel vasculitis where 40% of patients present with serum anti-neutrophil cytoplasmic antibodies (ANCA). We examined the presence and c...

Medical and Biotech [MESH] Definitions

Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).

Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).

Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.

Immune complex disease caused by the administration of foreign serum or serum proteins and characterized by fever, lymphadenopathy, arthralgia, and urticaria. When they are complexed to protein carriers, some drugs can also cause serum sickness when they act as haptens inducing antibody responses.

Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in BACTERIAL ENDOCARDITIS; OSTEOMYELITIS and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test. This test needs to be distinguished from testing of the naturally occurring BLOOD BACTERICIDAL ACTIVITY.
