The cancer-immune interplay and its role on the evolution of NSCLC might be disclosed through detection local systemic cues. Aim: To determine whether peripheral blood (PB) immune profiles may mirror clinically relevant tumor microenvironmental (TIME) features in resected patients. Tissue PB samples were prospectively collected at surgery from 80 consecutive stage I-IIIA cases. immunohistochemi...

Abstract Modern therapeutic strategies for precancerous cervical intraepithelial neoplasia (CIN) focus on immune-modulatory and cancer vaccination. The local immune status in CIN could influence HPV infection persistence, progression carcinogenesis. We analysed the role of FOXP3+ regulatory T lymphocytes, CD4+ CD8+ lymphocytes I, II III patients with without infection. Sixty-two were enrolled s...

human t-cell lymphotropic virus type 1 (htlv-1) is associated with adult t-cell leukemia/lymphoma (atl) and htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and ham/tsp is the most common clinical manifestation of the virus. ham/tsp is an inflamma...

immunophenotyping of lymphocytes is very essential for evaluation of immune system. due  to  the  effect  of  environmental  factors  and  ethnical diversity on  immune  system, establishment of an internal normal range of lymphocyte subsets is a necessity for each population.  the  aim  of  this  study  was  to  determine  the  normal  range  of  t  and  b lymphocytes, and nk cells in normal i...

BACKGROUND There is a growing body of evidence to suggest that CD8+ T lymphocytes contribute to local allergen-induced eosinophilic inflammation. Since bone marrow (BM) responses are intricately involved in the induction of airway eosinophilia, we hypothesized that CD8+ T lymphocytes, as well as CD4+ T lymphocytes, may be involved in this process. METHODS Several approaches were utilized. Fir...

Human immunodeficiency virus (HIV)-infected CD8 lymphocytes have been reported in vivo, but the mechanism of infection remains unclear. Experiments using the thy/hu mouse model support export of intrathymically infected CD8 precursors, while recent in vitro data suggest that mature CD8 lymphocytes upregulate CD4 upon activation (generating a CD8bright CD4dim phenotype) and are susceptible to HI...

BACKGROUND The aim of this study was to analyse changes in levels of memory T-lymphocytes during growth of SL2 tumours in DBA/2 mice and to evaluate whether these lymphocytes may have an inhibitory effect on tumour growth. MATERIALS AND METHODS Percentages of naïve (CD8+CD44lowCD62L+), central memory (CD8+CD44high CD62L+) and effector memory (CD8+CD44highCD62L-) lymphocytes in the CD8+ subset...

Background: Azathioprine is an immunosuppressive agent that is used in a variety of dermatologic, digestive and hematologic disorders in both humans and small animals. Aims: The effects of long term Azathioprine administration on complete blood count, rate of CD4+ and CD8+ lymphocytes, serum immunoglobulins and protein concentrations of mixed-breed dogs were evaluated in this study. Methods: 24...

background: although the pathogenesis of diabetes type 1 (t1d) is not fully elucidated. different clusters of lymphocytes such as cd4+ and cd8+ t cells are involved in it. moreover, the mechanism of how stem-cell therapy results in significant therapeutic outcomes in diabetes remains obscure. in the current study, we aimed to analyze lymphocyte subsets in patients with t1d before and after trea...

background: determination of the division history of t cells in vitro is helpful in the study of effector mechanisms against infections. technique described here uses the intracellular fluorescent label carboxyfluorescein diacetate succinimidyl ester (cfse) to monitor the proliferation. methods: in a cross sectional study, blood samples were collected from 7 volunteers with history of cutaneous...
