Immunofluorescence studies showing brain occludin and claudin-5 expression in mice after 14 days of JUUL/TS exposure and MCAO. A Immunofluorescence images of brain slices where green color represents occludin while blue color represents DAPI (nuclear marker). Quantification of contralateral (B) and ipsilateral (C) occludin expression relative to DAPI, expressed as a percentage. D Immunofluorescence images of brain slices where red color represents claudin-5 while blue color represents DAPI (nuclear marker). Quantification of contralateral (E) and ipsilateral (F) claudin-5 expression relative to DAPI, expressed as a percentage. Contralateral, non-injured hemisphere of the stroke brain; ipsilateral, injured hemisphere of the stroke brain. *P < 0.05, **P < 0.01; n = 4 mice for each group
