This site contains three datasets for developing algorithms that predict peptides binding to MHC class II molecules and/or activating CD4+ T-cells.

1. MHC class II peptide binding affinities for 16 alleles: peptide_affinity_dataset.zip

2. PDB structures used for binding core prediction: non_redundant_pdb_core_pep_allele.txt

3. CD4+ T-cell activation: LCMV_T_cell_activation.txt
