Tuberculous pleurisy (TBP) is a frequent extrapulmonary manifestation characterized by the accumulation of inflammatory cells that can sometimes be spontaneously self-cured. To achieve a greater insight into T cells at a local site, we systematically characterized and compared the numbers of antigen-specific T cells responding to BCG- or MTB-specific(More)
Important advances have been made in the immunodiagnosis of tuberculosis (TB) based on the detection of Mycobacterium tuberculosis (MTB)-specific T cells. However, the sensitivity and specificity of the immunological approach are relatively low because there are no specific markers for antigen-specific Th cells, and some of the Th cells that do not produce(More)
B-cell biology has been largely uncharacterized in the field of tuberculosis (TB). In this study, we investigated the immunophenotypical and functional characteristics of B cells obtained from the pleural fluid (PF) and peripheral blood of patients with tuberculous pleuritis (TP). Our results indicated that the total numbers of B cells, CD27(+) memory B(More)
Th1 cell-mediated immune responses at the site of active infection are important to restrict the growth of M. tuberculosis (MTB) and for the spontaneous resolution of patients with tuberculous pleurisy (TBP). In the present study, we found that without any stimulation, CD4(+) T cells in pleural fluid cells (PFCs) from patients with TBP expressed(More)
Most of the studies evaluating the function of tuberculosis (TB)-specific T cells were only based on the ability to produce cytokines, which may not fully reflect the function of T cells. In the present study, we confirmed that Bacille Calmette Guerin (BCG) could significantly induce cytokine production by CD4(+) T cells from BCG-vaccinated PPD(+) donors.(More)
T cell-mediated immunity is critical for the control of Mycobacterium tuberculosis infection. Identifying the precise immune mechanisms that lead to control of initial M. tuberculosis infection and preventing reactivation of latent infection are crucial for combating tuberculosis. However, a detailed understanding of the role of T cells in the immune(More)
BACKGROUND Genome wide association studies (GWAS) have proven useful as a method for identifying genetic variations associated with diseases. In this study, we analyzed GWAS data for 61 diseases and phenotypes to elucidate common associations based on single nucleotide polymorphisms (SNP). The study was an expansion on a previous study on identifying(More)
Natural killer (NK) cells are known as innate immune lymphocytes that respond rapidly when challenged by pathogens but little is known about adaptive immune features including memory related to NK cells from human beings. In the present study, we demonstrate for the first time that human NK cells expressing the memory-associated marker CD45RO were(More)
In this paper, we consider the problem of pilot based data transmission in massive multiple-input multiple-output (MIMO) systems where each receiver antenna is equipped with a low-precision analog-to-digital converter (ADC). Under the quantized MIMO setting, we derive a tight approximation of the uplink spectral efficiency considering a maximal ratio(More)
BACKGROUND Complications from skeletal-related events (SREs) constitute a challenge in the care of cancer patients with bone metastasis (BM). OBJECTIVES This study evaluated the comparative effectiveness of pamidronate, ibandronate, zoledronate, and denosumab in reducing the morbidity of SREs in cancer patients with BM. METHODS Medline (1948 to January(More)
