CNR1 and metabolic dysfunction-associated steatotic liver disease: The confocal images of HepaRG cells after treatment with exosomes derived from NAFLD patients show a significant increase (** p < 0.001) in the expression in terms of fluorescence level of FZD 7 and CB1R when the cells were treated with exosomes derived from NAFLD patients compared to the control cells (Figure 4 Panel A,C), reaching a double value compared to the control for FZD 7 expression and 20% more for CB1R (Figure 4 Panel B,D).
