Aims/hypothesis. Monocyte chemoattractant protein-1 (MCP-1) attracts monocytes and T lymphocytes, and could thus contribute to mononuclear cell infiltration in Type I (insulin-dependent) diabetes mellitus. Cytokines induce MCP-1 mRNA expression in pancreatic rat beta cells. To investigate this issue, we analysed the signal transduction for IL-1β-induced(More)
Aims/hypothesis. Cytokines and chemokines are important mediators of immune responses due to their ability to recruit and activate leukocytes. Using microarray analysis we observed that rat beta cells exposed to IL-1β and IFN-γ have increased mRNA levels of chemokines and IL-15. The aim of this study was to characterize the expression of IP-10, MIP-3α,(More)
We present the efficient generation of coherent single photons based on quantum dots in micropillars. We utilize a scalable lithography scheme leading to quantum dot-micropillar devices with 74% extraction efficiency. Via pulsed strict resonant pumping, we show an indistinguishability of consecutively emitted photons up to 98.5%.
Aims/hypothesis. Interleukin-1β is a putative mediator of pancreatic beta-cell dysfunction and damage in Type I (insulin-dependent) diabetes mellitus. To better understand the molecular mechanisms involved in IL-1β effects, we carried out a differential display of mRNA by RT-PCR to identify novel cytokine-regulated genes. Methods. Fluorescence activated(More)
