Presentation of viral peptide and protein segregated with DQA1 allele , because cell lines bearing DQA1*0501/DQB1*0201 heterodimers presented antigen in proliferation and cytotoxicity assays much more efficiently than cell lines bearing DQA1*0201/DQB1*0201 .
 protein: DQA1*0201/DQB1*0201; DNA: DQA1 allele; protein: DQA1*0501/DQB1*0201 heterodimers; cell line: cell lines
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
