Project description:To screen genes regulated by tachykinin in the 2-weeks mouse ovary, we have performed microarray expression profiling. COX-2 gene expression was upregulated in the mouse ovary treated with tachykinin receptor agonist compared to the mouse ovary treated with tachykinin receptor antagonists.
Project description:To investigate the similarity of toll-like receptor tolerance in macrophages stimulated with different toll-like receptor ligands we stimulated naïve or tolerant macrophages with ligands for TLR4, TLR2, TLR3 and TLR9. The data identifies a core set of genes that are tolerised by all ligands and genes that show TLR specific patterns.
Project description:We studied the effect of ligation on chemokine receptor CX3CR1 in the mouse bone marrow-derived macrophages (BMDM). We compared transcriptional profiles of BMDM treated with CX3CL1 and those of CCL26 to test if these two CX3CR1 ligands regulate differently.
Project description:Infectious pneumonias exact an unacceptable mortality burden worldwide. Efforts to protect populations from pneumonia have historically focused on antibiotic development and vaccine-enhanced adaptive immunity. However, we have recently reported that the lungs’ innate defenses can be therapeutically induced by inhalation of a combination of synthetic TLR ligands that synergize to protect mice against otherwise lethal pneumonia. Simultaneous treatment with ligands for TLR2/6 and TLR9 conferred robust, synergistic protection against virulent Gram-positive and Gram-negative pathogens, as well as viruses. Protection is associated with rapid pathogen killing in the lungs, and pathogen killing can be induced from lung epithelial cells in isolation. Here we explore the mechanisms underlying this dramatic phenomenon by performing microarray gene expression analysis of mouse lungs treated by aerosol with PBS (sham treatment), Pam2CSK4 (TLR 2/6 ligand), ODN2395 (TLR9 ligand), or both TLR ligands.
Project description:Analyzed differentially expressed genes among FOP- or resFOP-iMSCs treated by several ligands: Activin-A, 100 ng/mL; BMP-7, 100 ng/mL; TGF-B3, 10 ng/mL Comparison of gene expressions among FOP- or resFOP-iMSCs treated 16h by several ligands
Project description:These samples are part of a study in which we demonstrate that mast cells express the receptor CRTH2, which is the target for our antagonist compound compound A. We want to examine whether there are differences in RNA expression when the mast cells are treated with the ligands of CRTH2 - PGD2 and DK-PGD2 - compared to no treatment. Also, we want to see if pretreating the cells with compound A can block or change differences in RNA expression induced by either DK-PGD2 or PGD2. The study also looks at Ige loaded cells exposed to antigen and dexamethasone, and cells treated with BW868c - a a highly selective DP receptor antagonist.
