Fig. 2. Depletion of monocytes in clodronate liposome-treated mice. CD3⁻CD45RA⁻ non-lymphoid cell frequency was slightly reduced in clodronate liposome-treated mice (c) compared to PBS liposome-treated mice (a). A more than 50% reduction of F4/80⁺CD11b⁺ monocytes was observed among the CD3⁻CD45RA⁻ population in clodronate liposome-treated mice (d) compared to PBS liposome-treated mice (b).
