Project description:Homeostatic interactions between the host and its resident microbiota is important for normal physiological functions and if altered, it could lead to dysbiosis, a change in the structure and function of the microbiota, and as a result to various pathophysiologies. Altered structure in bacterial community is associated with various pathophysiologies, but we are just beginning to understand how these structural changes translate into functional changes. Environmental factors including pathogenic infections can lead to altered interactions between the host and its resident microbiota. We used microarray analysis and a C. elegans model system to gain insights on the mechanisms of functional changes in host-commensal bacteria interaction in the presence or absence of G. duodenalis and identified expression pattern in commensal bacteria that are characteristic of homeostatic and dysbiotic interactions. E. coli HB101 exposed to C. elegans in the presence or absence of G. duodenalis conditioned S-basal complete media for 24 hours were used for RNA extraction and hybridization on Affymetrix microarrays. We collected expression data for E. coli HB101, E. coli HB101 exposed to C. elegans, E. coli HB101 exposed to Giardia conditioned media, and E. coli HB101 exposed to both C. elegans and Giardia conditioned media.

Project description:CRISPR screen: U2OS or U2OS p53KO cells expressing Cas9 were transduced with a whole-genome library of CRISPR sgRNAs, then treated with either DMSO or etoposide. Differential sgRNA abundances were calculated for each condition and used to determine the effect of each single gene knockout on fitness and the drug-induced death rate. RNA-Seq: U2OS or U2OS p53KO cells were cultured with either DMSO or etoposide for 48 hours, and then U2OS cells were incubated in this conditioned media for 8 hours. RNA was collected and use to observe differential expression changes between conditions.

Project description:<p>High-throughput linking of T cell receptor (TCR) sequences to their binding antigens is vital for immune profiling, yet challenging. We present Tetramer associated TCR Sequencing (TetTCR-Seq) to address this challenge. Binding is determined using a library of DNA-barcoded antigen tetramers that are rapidly and inexpensively generated using an in vitro transcription/translation platform. We included CMV+ donors (CMV seropositive donors who are infected with Cytomegalovirus) to screen for CMV specific TCRs.</p>

Project description:Methods: Two human lung primary fibroblast (HLF) lines were activated for 24 h with eosinophil conditioned media obtained from two blood eosinophil donors. Total RNA was extracted from HLF and treated with DNase. RNA quality was analyzed via Agilent 2100 Bioanalyzer platform. The sequencing library from mRNA was prepared using TruSeq Stranded mRNA Library Preparation Kit (Illumina; San Diego, CA, USA) and RNA-seq (1x100 bases; 25 million reads per sample) was carried out using Illumina HiSeq 2500 platform. SeqMan Ngen (v.13) and ArrayStar with Qseq module (v.13) software packages (DNAStar, Madison, WI) were used to map sequence reads to human reference genome (GRCh38), apply statistical analyses and identify global gene expression changes. Results: Compared to control HLF cultures, conditioned medium from IL-3-primed degranulated eosinophils on IgG upregulates 169 genes and downregulates 131 genes in both HLF lines. Conclusions: Our study represents the first detailed analysis of gene expression in HLF activated with degranulated products from eosinophils, generated by RNA-seq technology. Analyses of the genes which expression level is changed by conditioned media from degranulated eosinophils should inform on the function of eosinophils on fibroblasts.

Project description:Cancer treatment has been revolutionized by immune checkpoint inhibitors, which regulate immune cell function by blocking the interactions between immune checkpoint molecules and their ligands. The interaction between programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) is a target for immune checkpoint inhibitors. Nanobodies, which are recombinant variable domains of heavy-chain-only antibodies, can replace existing immune checkpoint inhibitors, such as anti-PD-1 or anti-PD-L1 conventional antibodies. However, the screening process for high-affinity nanobodies is laborious and time-consuming. Here, we identified high-affinity anti-PD-1 nanobodies using peptide barcoding, which enabled reliable and efficient screening by distinguishing each nanobody with a peptide barcode that was genetically appended to each nanobody. We prepared a peptide-barcoded nanobody (PBNb) library with thousands of variants. Three high-affinity PBNbs were identified from the PBNb library by quantifying the peptide barcodes derived from high-affinity PBNbs. Furthermore, these three PBNbs neutralized the interaction between PD-1 and PD-L1. Our results demonstrate the utility of peptide barcoding and the resulting nanobodies can be used as experimental tools and antitumor agents. Peptide barcoding can be used to screen for molecules other than nanobodies. Our methods, such as the design of peptide barcodes, the design of peptide-barcoded molecules, preparation of peptide-barcoded molecule library, and quantification of peptide barcodes, are helpful in screening for peptide-barcoded molecules.
