To determine whether the genes differentially expressed in relation to diabetes onset were predominantly expressed by myeloid or lymphoid cells, we pooled PB from seven NOD.CD45.2 mice aged 9–10 weeks and sorted myeloid and lymphoid cells by surface expression of CD11b and CD3/B220, respectively, then analyzed gene expression by qPCR. The gene discussed is ITGAM; the disease is diabetes mellitus.
