Poly i:c stimulation of human monocytes
WebPreterm infants are more susceptible to severe bacterial and viral infectious diseases than their full-term counterparts. A major contributor to this increased susceptibility may be due to differences in their ability to respond to pathogens. While studies have demonstrated altered bacterial Toll-like receptor (TLR) responses, there is limited data on viral TLR … We analyzed expression patterns of TLR7 and TLR8 by flow cytometry in peripheral blood leukocyte subsets, i.e. monocytes, γδ T cells, neutrophils as well as NK cells. For comparison, we used HEK cells stably transfected with TLR7 or TLR8, respectively. As shown in a representative experiment (Suppl. Fig. … See more PBMC were activated with various TLR subset-specific RNA ligands and for comparison with well characterized non-RNA small molecule ligands, in the absence or presence … See more In the experiments presented so far, we described the co-stimulatory effect of TLR8 RNA ligands on the IFN-γ induction in Vδ2 T cells within … See more Next, we investigated the potential responsiveness of freshly isolated γδ T cells to co-stimulation with TLR8 RNAs. To this end, γδ T cells … See more
