The existence of four subpopulations in resting porcine T lymphocytes is documented. In addition to the two known subpopulations which are typified by a mutually exclusive expression of either the CD8 or the CD4 differentiation antigen, CD4-CD8+ and CD4+CD8- T lymphocytes, respectively, two unusual subpopulations were prominent not only in peripheral blood, but also in lymphoid tissues: CD4-CD8...

conclusions the cd4+ and cd8+ tcr vβ gene families undergo clonal expansion in cshb patients, and cd8+ t cells play a major role in the pathogenesis of cshb. moreover, the conserved motifs and limited use of joining region genes observed in the cshb patients of this cohort indicated that similar antigenic epitopes are recognized. results the number of oligoclonal or monoclonal expansion tcr vβ ...

It is known that asbestos exposure can cause malignant mesothelioma (MM) and that CD8(+) T cells play a critical role in antitumor immunity. We examined the properties of peripheral blood CD8(+) lymphocytes from asbestos-exposed patients with pleural plaque (PL) and MM. The percentage of CD3(+)CD8(+) cells in PBMCs did not differ among the three groups, although the total numbers of PBMCs of th...

Background and Aim: IPB-D2 chickens are selected from IPB-D1 due to their disease-resistance characteristics. One-way evaluate the strength of a chicken’s immune system is by examining number circulating T lymphocytes. This assessment can be conducted using modern analytic method called flow cytometry which relies on monoclonal antibodies detect relative proportions each cell measure quality qu...

Background. Colorectal cancer (CRC) is one of the most common malignant neoplasms in world. It ranks third structure oncological morbidity and second mortality. The liver site metastatic spread CR 14 to 18% patients have metastases at diagnosis. Radiofrequency ablation currently promising method treating lesions.

Differences in CD8(+)CD57(-) and CD8(+)CD57(+) lymphocyte lifespan have been documented. Lower numbers and shorter lifespan are characteristic of CD8(+)CD57(+) in normal individuals. However, CD8(+)CD57(+) are expanded in certain disease states including T cell large granular leukemia and other hematologic malignancies. The mechanisms responsible for the differences in CD8(+)CD57(-) and CD8(+)C...
