    Immune Epitope Database & Analysis Resource tcdb peptide library
    <t>TcdB</t> 1918 and TcdB 1961 <t>are</t> <t>immunodominant</t> epitopes following vaccination. (A) Amino acid sequences from TcdB peptide library . 15mers were analyzed using the Immune epitope database MHC-II peptide binding prediction for H2-IAb. Data were represented as adjusted rank which is generated by comparing each peptide’s score to a database of 15mers. Lower numbers are predicted to be better binders to H2-IAb. (B) Representative FACS plots showing frequency of TcdB pooled peptide library, individual peptides, or DMSO stimulated CD4 + T cells expressing IFN-γ. (C) The total number of IFN-γ + CD4 + T cells responding to TcdB peptide library or individual peptides. To account for the background cytokine production observed, the total number of IFN-γ + CD4 + T cells in the DMSO group was subtracted from the total number of peptide-responsive IFN-γ + CD4 + T cells. Naïve n=5 and TcdB-CROPs mRNA vaccinated n=5 per timepoint. Two-way ANOVA with Tukey’s multiple comparison test. Statistical significance is indicated as follows: ** P < 0.01; **** P < 0.0001. Representative FACS plots were pre-gated based on the following parameters: Singlets, Live, Lymphocytes, CD45 + , CD3/5 + , CD4 + CD44 + , CD62L lo . Frequency of parental gate +/− standard error of the mean is shown in green. Cells were stimulated with peptide or DMSO for 1 hour before the addition of BFA-M. Cells were incubated for an additional 4 hours before intracellular cytokine staining and analysis by flow cytometry.
