(Submitter supplied) CD3-positive T cells were negatively isolated from 10 SLE patients and 9 healthy controls without SLE. All of the SLE samples and control samples were compared with one another to identify baseline differences in expression due to the disease. Next, T cell preparations from 4 of the control subjects were stimulated with either Nitric Oxide (NOC-18) 600 uM for 24hr or stimulated through CD3/CD28 for 24hr to determine which genes were responsive to these signaling mechanisms. more...

Analysis of healthy T cells stimulated with CD3/CD28 (a Ca2+ fluxing inducer) or NO (a key trigger of mitochondrial hyperpolarization (MHP)). Enhanced Ca2+ fluxing and MHP underlie aberrant T-cell activation in SLE. Results provide insight into the molecular basis of T cell dysfunction in lupus.

(Submitter supplied) To identify any differentially expressed miRNAs in the CD4+ T cells of lupus. MicroRNAs (miRNAs) have been implicated as fine-tuning regulators controlling diverse biological processes at the level of posttranscriptional repression. Dysregulation of miRNAs has been described in various disease states, including human lupus. By using high-throughput microRNA profiling analysis, we identified that two miRNAs (miR-21 and miR-148a) overexpressed in CD4+ T cells from both lupus patients and lupus-prone MRL/lpr mice,which promote cell hypomethylation by repressing DNA methyltransferase 1 (DNMT1) expression.

(Submitter supplied) Systemic Lupus Erythematosus (SLE) is an autoimmune disease that affects 20-150 out of 100,000 people globally. Reactive oxygen species (ROS) generation from mitochondrial dysfunction contributes to risk for SLE and autoimmune states and are potential targets for the treatment of autoimmunity. HRES-1/Rab4 (Rab4A) is a GTPase linked to mitochondrial oxidative stress and activation of the mechanistic target of rapamycin (mTOR), and has been linked to SLE pathogenesis. more...
