Project description:We tested orphan TCR autoreactivity using the peptide MHC-TCR chimeric receptor (MCR) co-culture system. In this system, cognate antigen recognition leads to TCR specific NFAT activation in MCR reporter cells expressing a mouse I-Ab MHC class II extracellular domain covalently linked to candidate peptides and an intracellular TCR signaling domain. We used mixed autoimmune bone marrow chimera spleens and kidneys as sources of cDNA to generate a transcriptome-wide library of natural autoantigen peptides . We cloned this cDNA-derived peptide (CDP) autoantigen library into the MCR retroviral backbone and transduced NFAT reporter cells to make a murine autoantigen MCR reporter library (MCR-Lib). We then used this library to screen orphan TCRs identified by scTCR-seq for autoreactivity.

Project description:The Moutan Cortex Radicis (MCR) has been used as an analgesic, sedative and anti-inflammatory agent. This study investigated the changes in gene expression by MCR treatment when stimulated with lipopolysaccharide (LPS) in cultured human gingival fibroblasts (HGFs) and the gene expression changes by the MCR when challenged with LPS using a microarray chip.

Project description:Background: The halophyte Mesembryanthemum crystallinum (ice plant) is a model for studying salt tolerance. The morphology, physiology, metabolism, and gene expression of ice plant have been studied for over 40 years. Although the complete genome sequence has not been revealed, large-scale analyses of gene expression profiling have drawn an outline of salt tolerance in ice plant. Despite ample information in the transcriptome, miRNA information has not been documented. Results: We examined responses to a sudden increase in salinity in ice plant seedlings. Using a fluorescent dye to detect Na+, we found that ice plant roots respond to an increased flux of Na+ by either secreting or storing Na+ in specialized cells. High-throughput sequencing was used to identify small RNA profiles in three-day-old seedlings treated with or without 200 mM NaCl. Totally 132 conserved miRNAs belonging to 22 families were found. The hairpin precursor of 19 conserved mcr-miRNAs and 12 novel mcr-miRNAs were identified. Target genes are involved in a broad range of biological processes: transcription factors that regulate growth and development, enzymes that catalyze miRNA biogenesis for the most conserved mcr-miRNA, and proteins that are involved in ion homeostasis and drought-stress responses for some novel mcr-miRNAs. After 6 h of salt stress, the expressions of most mcr-miRNAs were down-regulated, whereas the expressions of their corresponding target genes were up-regulated. Analyses of the functions of target genes revealed that cellular processes, including growth and development, metabolism, and ion transport activity were up-regulated in roots under salt stress. Conclusions: Analyses of small RNA profile of ice plant seedlings identified many conserved miRNA families and several novel miRNAs. The expression of ten conserved miRNAs and three novel miRNAs were reciprocally correlated to predicted targets hourly after salt stress. Based on the expression pattern of miRNA and target genes in combination with the observation of Na+ distribution, we suggest that ice plant roots respond effectively to increased salinity by using Na+ as an osmoticum for cell expansion and guard cell opening. Excessive Na+ could either be secreted through root epidermis or stored in specialized leaf epidermal cells. These responses are partially regulated at the miRNA-mediated post-transcriptional level.

Project description:The Moutan Cortex Radicis (MCR) has been used as an analgesic, sedative and anti-inflammatory agent. This study investigated the changes in gene expression by MCR treatment when stimulated with lipopolysaccharide (LPS) in cultured human gingival fibroblasts (HGFs) and the gene expression changes by the MCR when challenged with LPS using a microarray chip. Human gingival fibroblast were divided into three experimental groups; 1, C: Control, 2, LPS: LPS-treatment only, 3, MCR40: LPS- and MCR40-treatments. Total RNA was isolated from each experimental fibroblast (3 experimental group M-CM-^W 1 sample of each experimental group = total 3 samples).
