Immunofluorescence revealed significantly elevated Iba1+ cell density in both dMCAO and bacterial-treated groups versus sham controls at day 3 post-stroke (p < 0.05), with further amplification in S.t -ΔpGFGF21 (+) treated mice (p < 0.05; Fig. 9A-B). The gene discussed is AIF1; the disease is Stroke.
