Expression of the enzymes NAPE-PLD and FAAH, and CB2R genes in blood monocyte-derived macrophages (BMDMs). The ratio NAPE/FAAH was also reported. The measured mRNA levels were normalized with respect to GAPDH (housekeeping gene) and gene expression values were expressed as a percentage of arbitrary units ± SEM. * indicates significant difference versushealthy controls; ° indicates significant difference versus GcMAF untreated autistic BMDMs. P-values <0.05 were considered statistically significant. CTL, healthy control subjects;AU, autistic patients. Values were reported in percentage versus healthy control values.
