Fig. 6From: Potential role of astrocyte angiotensin converting enzyme 2 in the neural transmission of COVID-19 and a neuroinflammatory state induced by smoking and vapingSmoking altered neuroinflammatory and immunomodulatory cytokines in brain without significantly affecting ACE2 expression. A: Western blot detection of ACE2 expression in mouse brains exposed to experimental smoking. Top panel shows the western blot images. Bottom panel shows the quantitation of band intensity of the top panel. Ctr, TS and Juul: control, tobacco smoking and Juul electronic nicotine vaping group, respectively. B: Altered cytokines in the brains induced by experimental smoking exposure. Values are presented as mean ± SEM. n = 5–6. *: p < 0.05. ns: not statistically significantBack to article page
