The adaptive immune system has implications in pathology of Parkinson's disease (PD). Research data demonstrated that the peripheral CD4+ T-cell population decreased in pathogenesis of PD. The effect of damaged dopaminergic neurons on peripheral T cells of PD is still unknown. In this study, we constructed a neuronal and glial cells co-culture model by using human neuroblastoma cells SH-SY5Y an...

This study investigated the proteoglycan (PG)-dependent mechanism of Chlamydophila pneumoniae attachment to lymphocytic cells. Lymphoid Jurkat cells and epithelial HEp-2 cells were statically infected with C. pneumoniae (TW183). Transmission electron microscopy and assessment of inclusion-forming units indicated that the bacteria grew normally in Jurkat cells and were capable of producing secon...

Patients with intravenous heroin addiction are prone to recurrent infections and at times these infections are fatal. We evaluated the effect of morphine on the apoptosis of Jurkat cells and freshly isolated human T lymphocytes. Morphine promoted apoptosis of both the Jurkat cells and the freshly isolated T lymphocytes in a dose-dependent manner. DAGO, a specific mu receptor agonist, also promo...

In the capillary venules, blood cells auto-separate with red blood cells aggregating near the centre of vessel and the nucleated cells marginating toward the wall of vessel. In this experiment, we used cell margination to help enrich the Jurkat cells via a groove-based channel which provides a vertical expansion-contraction structure, wherein the red blood cells invade the grooves and push the ...

In this study, we characterize the function of the tumor suppressor gene PTEN in Jurkat T cells. We established stable clones of Jurkat T cells that inducibly express either wild-type or phosphatase-inactive PTEN. We show here that PTEN potently inhibited the growth and reduced the size of Jurkat cells. The growth-suppressive effect of PTEN was associated with its ability to induce apoptotic ce...

chronic lymphocytic leukemia (cll) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. many ferula species, including f. asa-foetida, synthesize terpenyloxy coumarins. one of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines.     in this study induction of apoptosis by umbelliprenin ...

We have previously demonstrated that human gingival fibroblasts rescue butyric acid-induced T-cell apoptosis via proinflammatory cytokines such as interleukin 6 (IL-6) and IL-11, which are produced by fibroblasts stimulated with butyric acid. In this study, we determined if T-cell adhesion to human gingival fibroblasts influenced the susceptibility of T cells to butyric acid-induced apoptosis. ...

We set out to identify miR-21 targets in Jurkat cells using a high-throughput biochemical approach (10.1016/j.biochi.2014.09.021[1]). Using a specific monoclonal antibody raised against AGO2, RISC complexes were immunopurified in Jurkat cells over-expressing miR-21 following lentiviral trasduction as well as in Jurkat control cells lines. A parallel immunoprecipitation using isotype-matched rat...

background: absent in melanoma 2 (aim2) is an intracellular microbial dsdna sensor which plays an important role in production of proinflammatory cytokines through apoptosis associated speck-like protein containing a caspase activation and recruitment domain (asc) and caspase-1. micro-rnas (mirnas) play important roles in regulation of immune related genes. however, there is little information ...
