WNT3A and metabolic dysfunction-associated steatohepatitis: The aims of the present study are to evaluate i) the activation states of liver macrophages in pNAFLD and the correlation with the progression towards NASH and with HPC response; ii) if the DHA administration in pediatric patients induces modifications on macrophage activation; and iii) the role of Wnt3a macrophage production on HPC response in pNAFLD.
