Total mRNA was extracted from T cells , and using RT-PCR , changes in the production of IL-2 and RA receptors ( RAR )- alpha , beta , gamma mRNA were determined.
 ( protein: RA receptors, None) , ( cell type: T cells, None) , ( RNA: beta, None) , ( RNA: gamma mRNA, None) , ( RNA: mRNA, None) , ( RNA: alpha, None) , ( protein: IL-2, None) , ( protein: RAR, None)
