“…7), revealing that mouse PBMCs had MMR1 or MMR2 for non-self MHCs. In contrast, human MMR2 mRNA was earlier reported to be expressed in PBMCs from 8 of the 16 healthy volunteers, although PBMCs from only 4 of these volunteers expressed HLA-B62 (Shimizu et al, 2010). Similarly, none of the 16 volunteers expressed HLA-B44, whereas PBMCs from only 3 volunteers [i.e., A(11,24)B(51,52); A(2,24)B(46,46); A(2,2) B(60,60)] expressed human MMR1 mRNA (Fig.…”
