BACKGROUND
Inflammation of the middle ear (otitis media) is very common and can lead to serious complications if not resolved. Genetic studies suggest an inherited component, but few of the genes that contribute to this condition are known. Mouse mutants have contributed significantly to the
OBJECTIVE
Increased vascular permeability and endothelial cell growth are important in the pathogenesis of otitis media with effusion (OME) and vascular endothelial growth factor (VEGF) is known to play an important role in the increased vascular permeability and angiogenesis associated with OME.
Nasal vaccination is an effective therapeutic regimen for preventing otitis media. In the development of nasal vaccine, an appropriate adjuvant is required. In the present study, we examined the efficacy of fms-like tyrosine kinase receptor-3 ligand (Flt3L) as a mucosal adjuvant. Flt3L was
Tubulin tyrosine ligase-like 1 (TTLL1) protein is a member of the tubulin tyrosine ligase superfamily of proteins that are involved in the posttranslational polyglutamylation of tubulin in axonemal microtubules within cilia and flagella. To investigate the physiological role of TTLL1, the authors
X-linked agammaglobulinemia (XLA) is a rare genetic disorder caused by mutations in the Bruton's tyrosine kinase (BTK) gene. These mutations cause defects in early B cell development. A patient with no circulating B cells and low serum immunoglobulin isotypes was studied as were his mother and
BACKGROUND
A disturbance in the immune system has been described in Turner syndrome (45,X), with an association to low levels of IgG and IgM and decreased levels of T- and B-lymphocytes. Also different autoimmune diseases have been connected to Turner syndrome (45,X), thyroiditis being the most
BACKGROUND
X-linked agammaglobulinemia (XLA) is a primary immune deficiency characterized by recurrent bacterial infections and profoundly depressed serum immunoglobulin levels and circulating mature B cells. It is caused by mutations of the Bruton tyrosine kinase (BTK) gene and is the most common
X-linked agammaglobulinemia (XLA) is a hereditary humoral immunodeficiency that results from Bruton's tyrosine kinase (BTK) gene mutations. These mutations cause defects in B-cell development, resulting in the virtual absence of these lymphocytes from the peripheral circulation. Consequently, this
OBJECTIVE
Otitis media (OM) is the most common disease in preschool age children related to passive cigarette smoking as risk factor. In this study, we investigate whether the cigarette smoking can induce the inflammation in human middle ear epithelial cell, and cigarette smoke-induced inflammation
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by a failure to generate immunoglobulins of all isotypes due to the absence of mature B cells and plasma cells, secondary to mutations in the Bruton's tyrosine kinase (Btk) gene. We report six patients with XLA, confirmed
Pseudomonas aeruginosa, a known biofilm-forming organism, is an opportunistic pathogen that plays an important role in chronic otitis media, tracheitis, cholesteatoma, chronic wounds, and implant infections. Eradication of biofilm infections has been a challenge because the biofilm phenotype
BACKGROUND
X-Linked agammaglobulinemia (XLA) is characterized by an arrest of B cell differentiation, leading to recurrent bacterial infections. Lifelong immunoglobulin replacement therapy (IRT) is indicated to prevent infections and their complications.
METHODS
A retrospective study of patients
OBJECTIVE
To explore the cells proliferation and its molecular regulating mechanisms of cholesteatomatous epithelium from the aspect of protein tyrosine kinases (PTKs) signal transduction and cell cycle control.
METHODS
The expressions of phosphated PTKs, CDK4 and p15 were investigated by
An 8-year-old boy presented with eczematous skin lesions, recurrent otitis media and unexplained pyrexias. X-linked agammaglobulinaemia was diagnosed and treatment commenced with intravenous immunoglobulin replacement therapy. X-linked agammaglobulinaemia (XLA) is a primary immunodeficiency syndrome
OBJECTIVE
X-linked agammaglobulinemia (XLA) is a humoral immunodeficiency disease caused by a mutation in the Bruton tyrosine kinase (BTK) gene resulting in defective B cell differentiation. Because it is a relatively rare disorder, it is difficult for clinicians to have a comprehensive
