Fig. 3. No difference in inflammatory activation in olfactory bulb between wt, rd1 and ak mice. (A) Immunofluorescence staining showed no difference of activated microglia (Iba1) or reactive astrocytes (GFAP) in the olfactory bulb of ak mice compared with wt and rd1 mice. The representative 10× and 40× images were shown. (B) Quantification of Iba1 positive cells; (C) Quantification of GFAP positive cells. The scale bar indicates 100 μm. N.S. = no significant difference.  n  = 4 for each group.
