respiratory tract infections/tyrosine

Carbonic anhydrase (CA) is an enzyme which plays role/roles in various homeostatic mechanisms, such as the acid-base balance and electrolyte secretion in various tissues. This study aimed to determine and to compare possible alterations in activity of this enzyme caused by use of bronchodilator

The pathogenesis of RA is a complex and ever-changing landscape but amid the chaos of the disease process we have found effective treatment regimes. However, our current therapeutics, although targeting various components of both the innate and adaptive immune response, do not result in disease

Background: X-linked agammaglobulinemia is a primary immunodeficiency disease caused by gene mutations of Bruton's tyrosine kinase (BTK). We found a new mutation point and summarized the correlation analysis and performed a

BACKGROUND X-linked agammaglobulinemia (XLA) is a heritable primary immune deficiency disorder caused by mutation of Bruton's tyrosine kinase (BTK) gene. The main clinical characteristics of XLA are recurrent respiratory tract infections and profoundly low serum immunoglobulin levels and B

Bovine herpesvirus 1 (BHV-1) causes respiratory infection and abortion in cattle. Following a primary infection, BHV-1 establishes lifelong latency in the trigeminal ganglia (TG). Periodic reactivation of the latent virus in TG neurons results in anterograde virus transport to nerve endings in the

We report a case of sporadic X-linked agammaglobulinemia previously diagnosed as variable immunodeficiency (VID). An 39-year-old male had recurrent episodes of respiratory tract infection since his early childhood. At the age of four, he developed partial paresis of the left limbs after polio

OBJECTIVE To test whether self-reported lower respiratory tract infections in early infancy predicted risk for islet autoimmunity in genetically predisposed children. METHODS The environmental triggers for type 1 diabetes (MIDIA) study recruited newborns in Norway to identify those with the human

Pseudomonas aeruginosa plays a major role in respiratory tract infections or sepsis in patients with cystic fibrosis or upon suppression of the immune system. Several P. aeruginosa strains have been shown to be internalized by human epithelial cells; however, the molecular mechanisms of the invasion

OBJECTIVE Tyrosine kinase inhibitors (TKIs) have well-characterized immunomodulatory effects on T and NK cells, but the effects on the humoral immunity are less well known. In this project, we studied TKI-induced changes in B cell-mediated immunity. METHODS We collected peripheral blood (PB) and

BACKGROUND Prolonged intense exercise has been associated with transient suppression of immune function and an increased risk of infections. In this context, the catabolism of amino acid tryptophan via kynurenine may play an important role. The present study examined the effect of a probiotic

BACKGROUND Spleen tyrosine kinase (Syk) is an important modulator of immune signaling. The objective of this phase 2 study was to evaluate the efficacy and safety of R788, an oral inhibitor of Syk, in patients with active rheumatoid arthritis despite methotrexate therapy. METHODS We enrolled 457

Tyrosine kinase 2 (TYK2) associates with interferon (IFN) alpha receptor, IL-10 receptor (IL-10R) beta and other cytokine receptor subunits for signal transduction, in response to various cytokines, including type-I and type-III IFNs, IL-6, IL-10, IL-12 and IL-23. Data on TYK2 dependence on cytokine

BACKGROUND Ibrutinib, an orally administered covalent inhibitor of Bruton's tyrosine kinase (BTK), is an effective treatment for relapsed chronic lymphocytic leukaemia (CLL). We investigated the activity and safety of the combination of ibrutinib with the monoclonal antibody rituximab in patients

Tyrosine kinase 2 (TYK2) deficiency was formerly defined in patients suffering from autosomal recessive hyperimmunoglobulin E syndrome (AR-HIES). In recent years, it was proposed that human TYK2 deficiency is probably not a common cause of the AR-HIES but a distinctive illness object.

Patients with chronic obstructive pulmonary disease (COPD) exhibit characteristics of airway mucus hypersecretion, including sputum production, increased luminal mucus, goblet cell hyperplasia and submucosal gland hypertrophy. These features are not common to all patients and the impact of
