Macrophage and T-cell infiltration in DRG of old WT and GLA KO mice. (A–D) Representative photomicrographs of CD11b+ macrophages and CD3+ T-cells (arrowheads) in DRG of old WT ((A,B), respectively) and old GLA KO mice ((C,D), respectively). (E) Quantification of CD11b+ macrophages per mm² DRG area in old WT (◯, n = 10) and old GLA KO mice (●, n = 10). (F) Quantification of CD3+ T-cells per mm² DRG area in old WT (◯, n = 10) and old GLA KO mice (●, n = 10). Abbreviations: CD = Cluster of Differentiation; DRG = dorsal root ganglia; GLA KO = alpha-galactosidase A knockout; WT = wildtype. Scale bar: 100 µm.
