AI Article Synopsis

  • Exposure to inflammatory cytokines activates STAT3 in T cells, particularly in those from systemic lupus erythematosus (SLE) patients.
  • Increased levels of total and phosphorylated STAT3 in SLE T cells are linked to higher expression of target genes involved in immune response.
  • Silencing STAT3 with small interfering RNA reduces T cell migration, indicating that targeting STAT3 might help correct migration issues seen in SLE.

Article Abstract

Exposure of T cells to inflammatory cytokines leads to phosphorylation-dependent activation of signal transducer and activator of transcription (STAT) 3. T cells from patients with systemic lupus erythematosus (SLE) display increased levels of total and phosphorylated STAT3 which resides primarily in the nucleus. Increased STAT3 is associated with increased expression of target genes. Silencing of STAT3 expression using a small interfering RNA approach resulted in decreased chemokine-provoked SLE T cell migration. Our data suggest that inhibition of STAT3 expression may reverse the signaling aberrations involved in SLE T cell migration.

Programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) interactions are targets for immunotherapies aimed to reinvigorate T cell function. Recently, it was documented that PD-L1 regulates dendritic cell (DC) migration through intracellular signaling events. In this study, we find that both preclinical murine and clinically available human PD-L1 antibodies limit DC migration.

The characterization of phenotypes in cells or organisms from microscopy data largely depends on differences in the spatial distribution of image intensity. Multiple methods exist for quantifying the intensity distribution - or image texture - across objects in natural images. However, many of these texture extraction methods do not directly adapt to 3D microscopy data.

Mitosis and meiosis have two mechanisms for regulating the accuracy of chromosome segregation: error correction and the spindle assembly checkpoint (SAC). We have investigated the function of several checkpoint proteins in meiosis I of Drosophila oocytes. Increased localization of several SAC proteins was found upon depolymerization of microtubules by colchicine.

Bacterial receptors feed into multiple signal transduction pathways that regulate a variety of cellular processes including gene expression, second messenger levels, and motility. Receptors are typically activated by signal binding to ligand-binding domains (LBDs). Cache domains are omnipresent LBDs found in bacteria, archaea, and eukaryotes, including humans.

Hepatocellular carcinoma(HCC) has a high mortality and morbidity rate and seriously jeopardizes human life. Chemicals and chemotherapeutic agents have been experiencing problems such as side effects and drug resistance in the treatment of HCC, which cannot meet the needs of clinical treatment. Therefore, finding novel low-toxicity and high-efficiency anti-hepatocellular carcinoma drugs and exploring their mechanisms of action have become the current problems to be solved in the treatment of HCC.
