Of note, mmu-miR-142, plays significant roles in immune regulation (Sun et al., 2011, 2013, 2015), and in the development of nasopharynx carcinoma, cell cycling or IL-6 modulation in hematopoietic cell tissues, mature T cell proliferation and endotoxin-induced mortality in inflammatory processes; However, the roles of the miRNAs described above except mmu-miR-155-5p and mmu-miR-146a-5p in the process of T. gondii colonization remain to be elucidated. The gene discussed is IL6; the disease is nasopharyngeal carcinoma.
