Prior investigations show that signaling activation through pattern recognition receptors can directly impact a number of inflammatory lung diseases. While toll-like receptor (TLR) 7 agonists have raised interest for their ability to inhibit allergen-induced pathological changes in experimental asthma conditions, the putative benefit of this treatment is limited by adverse effects. Our aim was ...

Ethambutol resistance in clinical Mycobacterium tuberculosis isolates is associated primarily with missense mutations in the embB gene. However, recent reports have described the presence of embB mutations, especially those at embB codon 306, in isolates susceptible to ethambutol. To clarify the role of embB mutations in ethambutol resistance, we sequenced the ethambutol resistance-determining ...

This phase 3 trial (Eastern Cooperative Oncology Group [ECOG] E1A06) compared melphalan, prednisone, and thalidomide (MPT-T) with melphalan, prednisone, and lenalidomide (mPR-R) in patients with untreated multiple myeloma (MM). A noninferiority design was used, and inferiority was defined as a progression-free survival (PFS) hazard ratio (HR) of MPT-T/mPR-R ≤0.82. A total of 306 patients enroll...

Substitutions of codon 306 in the gene embB are the most common mutations found in ethambutol resistant Mycobacterium tuberculosis. The characterization of these mutations has been hampered by the need for prior cultivation of the mycobacteria, or the need for DNA sequencing, or both. Here, we describe a simple and culture-independent technique to detect embB codon 306 mutations directly from s...

BACKGROUND The impact of intestinal helminth infection on the clinical presentation and immune response during active tuberculosis (TB) infection is not well characterized. Our aim was to investigate whether asymptomatic intestinal helminth infection alters the clinical signs and symptoms as well as the cell mediated immune responses in patients with active TB. METHODOLOGY Consecutive, newly ...

Antigen-specific helper T cells recognize a complex of peptide antigen and class II major histocompatibility complex (MHC) gene products. Whether T cells recognize MHC class II alloantigen by a similar mechanism or the native conformation of MHC molecules themselves has yet to be determined. The demonstration that peptide antigens bind directly and specifically to class II molecules has allowed...

BACKGROUND The signal transducer and activator of transcription 6 (STAT6) transduces signals in response to IL-4 and IL-13 cytokine stimulations, resulting in many cell-specific responses. Some common STAT6 SNPs were associated with asthma predisposition and/or IgE levels, although discrepancies have also been reported. OBJECTIVE To determine whether STAT6 rs324011 and rs324015 polymorphisms ...
