Our fourth T1D study has been added to the AIRR Data Commons, searchable through the iReceptor Gateway. Annotated T-cell receptors and subject HLA from Anderson et al. "Human islet T cells are highly reactive to preproinsulin in type 1 diabetes" is now available. This continues our exciting T1D data curation collaboration with The Sugar Science group, the Aaron Michels Lab (University of Colorado), and the Todd Brusko Lab (University of Florida) among others.
