title: An update on the role of miRNA-155 in pathogenic microbial infections.
abstract: MicroRNAs (miRNAs) are evolutionarily conserved and naturally abundant molecules of single-stranded, non-coding RNA from ∼17 to 25 nucleotides long. MiRNAs act at post-transcriptional level either to suppress gene translation or to induce mRNA degradation, according to the degree of complementarity with their target sequences. MiR-155 is a typical representative of the miRNA family that plays a crucial role in cell differentiation and organism development. A number of studies have shown that miR-155 can not only regulate cell proliferation, apoptosis and lymphoma progression, but also plays an important part in various other physiological and pathological processes. For instance, it is involved in hematopoietic cell differentiation, cardiovascular disease, inflammation and immune responses. In recent years, the role of miR-155 in infectious diseases has attracted considerable attention. This review will highlight the participation of miR-155 in the responses to infections caused by different pathogens.
