Mapping T cell responses to native and neo- islet antigen epitopes in at risk and type 1 diabetes subjects. Mapping T cell responses to native and neo- islet antigen epitopes in at risk and type 1 diabetes subjects

Gene expression and T cell receptor profiles from single cells from populations of T cells stimulated with islet autoantigenic peptides. CD4 T cells were stimulated with native (proinsulin, GAD fragments) or neo-antigen epitopes or flu vaccine (Pediacel). Activated cells (identified as CD19- CD3+ CD4+,CD45-RO+ CD95+, CD154+CD69+ CD27+) were FACS-sorted, barcodes for samples were introduced with cell hashing as follows: patient, 1 pool 1 (Hashtag 1); patient 1 pool 2 (Hashtag 2) patient 2 pool 1 (Hashtag 3); patient 2 pool 2 (Hashtag 4) and Pediacel (patient 1 and 2; Hashtag 5). Hashtag info in ADT files, TCR sequences provided in VDJ files.
