Alveolar resident memory T cells (T(RM)) comprise a currently uncharacterized mixture of cell subpopulations. The CD3(+)CD161(+) T cell subpopulation resides in the liver, intestine and skin, but it has the capacity for tissue migration; however, the presence of resident CD3(+)CD161(+) T cells in the bronchoalveolar space under normal conditions has not been reported. Bronchoalveolar cells (BAC...
We have recently reported that tumor-associated lymphocytes obtained from ascitic fluids of women with ovarian carcinoma (OvCA) demonstrate a marked decrease in expression of cytoplasmic CD3-zeta and surface CD3-epsilon chains, which is associated with altered function of T cell receptor (TcR). We now demonstrate that OvCAs in situ and in culture express functional Fas ligand (FasL), capable of...
Peripheral blood lymphocytes cultured in recombinant interleukin 2 during 3 to 5 days (short-term cultures) develop the ability to lyse natural killer-resistant tumor lines and fresh tumor cells, i.e., express lymphokine-activated killer (LAR) function. Phenotypic analysis has shown these cells to be natural killer cells, i.e., CD16+ and/or Leu 19+ cells. CD3*,CD16~ T-cells, instead, develop ve...
The clinical significance of NK-like T CD3+/CD16+CD56+ cells in chronic lymphocytic leukemia (CLL) is still a subject of controversy. There are few previous descriptions that this cell population can be qualitatively or quantitatively deficient in CLL patients. In the present study we investigated the clinical value of CD3+/CD16+ CD56+ cells as predictors of disease progression. We assessed the...
T cells have the capability of recognizing target cells through their T cell receptors (TCRs). Thus, the percentages of CD3+/gamma-delta (gammadelta) TCR+ and CD3+/alpha-beta (alphabeta) TCR+ T lymphocytes were investigated in active and inactive pulmonary tuberculosis (PT) patients and in healthy individuals. CD3+ and CD3+/alphabeta TCR+ cell percentages were significantly lower in all PT pati...
Five obligately anaerobic, Gram-stain-negative, saccharolytic and proteolytic, non-spore-forming bacilli (strains CD3 : 27, CD3 : 28(T), CD3 : 33, CD3 : 32 and CD3 : 34) are described. All five strains were isolated from the small intestine of a female child with coeliac disease. Cells of the five strains were short rods or coccoid cells with longer filamentous forms seen sporadically. The orga...
This study was designed to establish a more effective and safe culture system for adoptive immunotherapy by investigating the use of homologous cord blood plasma (HCBP) instead of fetal bovine serum (FBS), which has various limitations including ethical problems for the ex vivo expansion of human umbilical T lymphocytes. Fresh human umbilical mononuclear cell fractions were isolated by Ficoll-H...
Background and Aims: Mucosal-associated invariant T (MAIT) cells are striking lymphocyte population in the blood and their importance in immune responses is growing fast. The current study was conducted to evaluate leptin hormone effects on MAIT cell functions. Materials and Methods: Five healthy male donors in ages of 22-30 years were selected and peripheral blood mononuclear cells (PBMCs) ...
The CD3 protein complex is an important T cell marker. This study aimed at determining the lymphocytes count of apparently healthy adult subjects in Ekpoma, Nigeria. A total two hundred and sixty (260) were randomly recruited for study. both sexes belonged to 17 50 years age range. Five millitres (5ml) whole blood was collected from antecubital vein dispensed into Ethylene Diamine Tetraacetic A...
Introduction . The analysis of current publications indicates at our insufficient understanding subpopulation composition lymphocytes in peripheral blood and cerebrospinal fluid (CSF) during pediatric neuroinfectious diseases. It has been found that the main lymphocyte populations are divided into many small (minor) subpopulations. purpose this research was to assess percentage major minor CSF ...
