BACKGROUND Mycobacterium tuberculosis-specific CD8+ and CD4+ T lymphocyte responses restrict the spread of extracellular pathogens by limiting M.tuberculosis replication. Alterations in cytolytic function, inappropriate maturation/differentiation, and limited proliferation could reduce their ability to control M.tuberculosis replication. METHODS In an attempt to further characterize the immun...

Surgery is the primary therapeutic strategy for most solid tumours; however, modern oncology has established that neoplasms are frequently systemic diseases. Being however a local treatment, the mechanisms through which surgery plays its systemic role remain unknown. We have investigated the influence of cytoreduction on the immune system of primary and recurrent ovarian cancer. All ovarian can...

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...

BACKGROUND Systemic Lupus Erythematosus (SLE) is a complex chronic immunological disease characterized by increased B cell activity and altered T cell function. OBJECTIVE To investigate relationship between T lymphocyte subsets and cortisol with the disease activity of systemic lupus erythematosus patients in North India. MATERIALS AND METHODS The percentage of CD4(+) and CD8(+) T cells in ...

In order to examine the role of peripheral blood lymphocyte subsets on the diagnosis, treatment and prognosis of hemophagocytic lymphohistiocytosis (HLH), 30 affected children during the acute period of the disease and 30 healthy children within the same age range were selected to test their peripheral blood lymphocyte subsets using flow cytometry and compare these subsets. At the same time, th...

Objective(s): Regulatory T cells, including CD4+CD25+Fox3+ and CD8+CD28- cells play an important role in regulating the balance between immunity and tolerance. Since multiple sclerosis is an inflammatory autoimmune disease, regulatory T cells are considered to be involved in its pathogenesis. In this study, we investigated the circulatory numbers of the two mentioned types of regulatory T cells...

The number of microanatomical location of CD4 and CD8 lymphocytes, of cells bearing receptors for I12 and transferrin, and of monocyte/macrophages in the dermis at the site of a tuberculin test were measured in 13 patients with haemophilia (10 seronegative and three seropositive for human immunodeficiency virus (HIV]. The overall density of lymphocytes in the perivascular and diffuse parts of t...

The study included 24 patients, which formed the baseline group — 12 patients with pulmonary tuberculosis in combination COVID-19 infection and control tuberculosis. There were studied leukocyte formula, content of CD3, CD4, CD8 lymphocytes, NO2-+NO3- total its metabolites. obtained results showed that there is a pronounced decrease lymphocytes an unexpressed shift formula to left. lymphocyte d...

UNLABELLED Proper immune restoration (CD4 count >500 and normal CD4/8 ratio) is reached only by a fraction of HIV patients, despite stable viral suppression. METHODS We present a case-control study to compare HIV patients with viral suppression >1 year, according to immune restoration pattern: adequate response (AR) defined by CD4 > 500 cells/mm(3) and CD4/8 ratio >1; partial response (PR = p...
