The authors show the transferrin receptor-related mRNA (TRFC) to be a target of this miRNA, and during ZIKV infection it negatively regulates TFRC levels in hNSC-derived neurospheres, resulting in neurosphere size reduction, which may be involved in the microcephaly phenotype (Dang et al., 2019). The gene discussed is TFRC; the disease is Zika virus infectious disease.
