Various degrees of infectivity were noted depending on cell type (S2 Fig), with minimal infection rates of B and T cells, except marginal zone B cells (9% LCMV+), and high infection rates of pDCs (45%), cDCs (49%), macrophages (81%), as well as monocytes and other CD11b+ cells (19%), of which Gr-1int cells were the most infected (38%), followed by Gr-1hi cells (14%) and Gr-1neg cells (11%). The gene discussed is ITGAM; the disease is infection.
