We found a negative correlation between miRNA-155 expression and inflammatory cytokine levels in AMD patients, which is in line with this miRNA pathway: it acts with IL-1 (Ceppi et al., 2009), TNF-α (Li et al., 2016), NF-κB (Wu et al., 2014), MyD88 and the inositol 5′-phosphatase SHIP-1 in infected macrophages (Bandyopadhyay et al., 2014). The gene discussed is TNF; the disease is age-related macular degeneration.
