We have examined changes in HS1 phosphorylation after differential stimulation of CD3 , CD2 , and CD28 to elucidate its role in T cells and to further delineate the signaling pathways recruited by these receptors.
 protein: CD2; protein: HS1; protein: CD3; cell type: T cells; protein: CD28
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
