Figure Lengend Snippet: Primary human monocyte-derived macrophages (hMDM) were treated with dopamine (10 -6 M) for 3 hours, and gene expression was assessed by qPCR. ( A ) Dopamine significantly increased HDAC2 mRNA expression (n=17 donors, *p<0.05). ( B ) Dopamine significantly increased HDAC6 mRNA expression (n=14 donors, *p<0.05). ( C ) KAT2A mRNA expression was not significantly altered by dopamine treatment(n=17 donors). ( D ) KDM6B mRNA expression was not significantly altered by dopamine treatment (n=17 donors).

Figure Lengend Snippet: Data from were stratified by donor sex and age to assess potential sources of inter-donor variability. ( A ) Dopamine significantly increased HDAC2 mRNA expression in hMDMs from female donors (n=10, *p<0.05) but not male donors (n=7). ( B ) Dopamine treatment showed an increasing trend in HDAC6 expression in male hMDMs (n=9; p=0.0742) and a non-significant increase in female hMDMs (n=5). Dopamine treatment did not reveal sex-associated differences in ( C ) KAT2A or ( D ) KDM6B gene expression (n=17 donors each). ( E ) Dopamine treatment showed an increasing trend in HDAC2 expression in donors under 40 years of age (n=8, p=0.0547), but not in donors aged 40 years or older (n=9). No age-associated differences were observed for dopamine-induced changes in ( F ) HDAC6 (n=14), ( G ) KAT2A (n=17), or ( H ) KDM6B (n=17) expression.
