Background: Thermal burn injuries impair the host defence system. Hence, in the present study, we aimed at investigating the changes in the number and phenotype of peripheral blood lymphocyte populations (T, B, and natural killer cells) and their subpopulations in patients with thermal burns and determining the relationships with different sizes of total body surface area (TBSA). ...
Increased lymphocyte turnover is a hallmark of pathogenic lentiviral infection. To investigate perturbations in lymphocyte dynamics in natural hosts with nonpathogenic simian immunodeficiency virus (SIV) infection, the nucleoside analog bromodeoxyuridine (BrdU) was administered to six naturally SIV-infected and five SIV-negative sooty mangabeys. As a measure of lymphocyte turnover, we estimated...
لپتین یکی از مهمترین هورمونهای مترشحه بافت چربی با نقش محوری در تنظیم ثبات انرژی و متابولیسم از طریق اشتها و گرسنگی است. علاوه بر کنترل وزن، لپتین نقش مهمی نیز در تنظیم پاسخهای ایمنی دارد. در افراد بدون نقص ژنتیکی در تولید لپتین و در بیان گیرنده آن، کاهش بیش از حد لپتین باعث افت عملکرد سیستم ایمنی و فراهم شدن شرایط ایجاد عفونت و افزایش بیش از حد آن از طریق تحریک سلولهای t و افزایش سایتوکین های ...
Trichloroethylene (TCE) is a volatile chlorinated organic compound that is commonly used as a solvent for lipophilic compounds. Although recognized as an animal carcinogen, TCE's carcinogenic potential in humans is still uncertain. We have carried out a cross-sectional study of 80 workers exposed to TCE and 96 unexposed controls matched on age and sex in Guangdong, China to study TCE's early bi...
The objective of the present study was to investigate the effect of transoral endoscopic adenoidectomy on peripheral blood T lymphocyte subsets in pediatric patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and its treatment strategy. Ninety-eight pediatric patients with adenoidal hypertrophy associated with OSAHS admitted to the Department of Otolaryngology, Xuzhou Children's Hos...
OBJECTIVE To investigate the differences of T lymphocyte subgroups and high-sensitivity C reactive protein (HsCRP) levels among patients with venous thromboembolism (VTE), VTE patients with infection, simple infection patients and the normal controls. METHOD 289 patients were enrolled in this study and divided into control group, VTE group, VTE with infection group and simple infection group....
BACKGROUND Increased activation and increased survival of T lymphocytes characterise bronchial asthma. OBJECTIVES In this study the effect of budesonide on T cell survival, on inducible co-stimulator T cells (ICOS), on Foxp3 and on IL-10 molecules in T lymphocyte sub-populations was assessed. METHODS Cell survival (by annexin V binding) and ICOS in total lymphocytes, in CD4+/CD25+ and in CD...
OBJECTIVE To evaluate the influence of dimethyl fumarate (DMF, Tecfidera) treatment of multiple sclerosis (MS) on leukocyte and lymphocyte subsets. METHODS Peripheral blood leukocyte and lymphocyte subsets, including CD3(+), CD4(+), and CD8(+) T cells; CD19(+) B cells; and CD56(+) natural killer (NK) cells, were obtained at baseline and monitored at 3 months, 6 months, and 12 months after ini...
BACKGROUND The pathophysiology of chronic obstructive pulmonary disease (COPD) includes inflammation, oxidative stress, an imbalance of proteases and antiproteases and apoptosis which has been focused on lately. Abnormal apoptotic events have been demonstrated in both epithelial and endothelial cells, as well as in inflammatory cells including neutrophils and lymphocytes in the lungs of COPD pa...
The current knowledge of CD4 function is limited to its role as a necessary coreceptor in TCR-initiated signaling. We have investigated whether CD4 regulates additional T cell functions. Using human primary resting CD4+ T cells, we demonstrate that CD4 activation is sufficient to induce lymphocyte death. Immediately after CD4 cross-linking, CD4+ T cells are rendered susceptible to apoptosis med...
