Rebecca Foulger commented on gene: MIR155: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): MIR155 (also referred to as BIC) is an endogenous noncoding RNA involved in regulation of the immune response, in particular T-cell differentiation, and in regulation of innate immunity (PMID: 32233818; 217121651;1746328969;20852130). This miRNA has been associated with various virus infections (PMID: 32233818;28139244;23686237;26072128). miR-155-5p expression has been shown to be induced in mice infected with influenza A virus (PMID: 32308197 - in this study, lung injury by ARDS was attenuated by deletion of miR-155, making this miRNA a potential therapeutic target in the context of COVID-19). Through single cell and bulk RNA profiling of SARS-CoV-2 and SARS-CoV infections in three human cell lines (H1299, Caco-2 and Calu-3 cells), Emanuel et al. (2020) (bioRxiv preprint doi: https://doi.org/10.1101/2020.05.05.079194) demonstrated strong expression of the immunity and inflammation-associated microRNA miRNA-155 upon viral infection with both viruses. Both viruses triggered a 16-fold upregulation of one form of miR-155 and a 3-fold upregulation of another. A role for MIR155 in viral susceptibility for a range of viruses and the immune response has also been demonstrated in a series of mouse models: PMID 23601686: In Mir155 -/- mice, Dudda et al. (2013) observed severely reduced accumulation of Cd8-positive T cells during acute and chronic viral infections with impaired control of viral replication. Lack of Mir155 led to an accumulation of Socs1 resulting in defective cytokine signaling through Stat5. Dudda et al. also concluded that MIR155 and its target, SOCS1, are key regulators of CD8-positive T cells. PMID 23275599: Lind et al. (2013) found that mice lacking Mir155 had impaired Cd8 positive T-cell responses to infections with lymphocytic choriomeningitis virus and the intracellular bacteria Listeria monocytogenes and concluded that MIR155 is required for acute CD8-positive T-cell responses and proposed that targeting MIR155 may be useful in modulating immune responses. PMID 24516198: Bhela et al. (2014) – 75 to 80% of MIR155 null mice infected ocularly with herpes simplex virus (HSV)-1 developed herpes simplex encephalitis with elevated viral titers in brain, but not in cornea. Immunohistochemical and flow cytometric analyses in Mir155-null mice showed diminished Cd8-positive T-cell numbers, functionality, and homing capacity. Adoptive transfer of HSV-1-immune Cd8-positive T cells to Mir155-null mice 24 hours after infection provided protection from HSE. The authors concluded that MIR155 deficiency results in enhanced susceptibility of the nervous system to HSV-1 infection. |
