Figure 4: NRG treatment inhibits M. pneumonia-induced autophagy. (a) Immunofluorescence shows the effect of NRG treatment on MP-induced autophagy plaque production. (b–e) Western blot detection shows the expression of autophagy relative protein LC3, P62, and Beclin-1 expression. Data are presented as the mean ± SD with Tukey–Kramer multiple comparison test analysis. . versus ctrl group; versus MPP group.
