遺伝子研究の概要
Plscr1, short for phospholipid scramblase 1, is a protein-coding gene with significant functions in multiple biological processes. It is involved in maintaining phospholipid distribution in cell membranes, and its expression can be induced by interferons (IFNs) [1,3,5,6,8]. PLSCR1 plays a crucial role in the host innate immunity against viral infections, and it has also been linked to cell apoptosis, cancer progression, and cell differentiation [1,2,4,5,6,7,9]. Genetic models, such as gene knockout mouse models, are valuable tools to study its functions.
In terms of viral infections, genome-wide CRISPR-Cas9 screens have identified PLSCR1 as a cell-autonomous restriction factor against live SARS-CoV-2 infection in human lung epithelia and hepatocytes. IFNγ-induced PLSCR1 restricts not only SARS-CoV-2 USA-WA1/2020 but also the Delta and Omicron lineages, and it acts on other highly pathogenic coronaviruses [1]. It interferes with the uptake of SARS-CoV-2 in both endocytic and TMPRSS2-dependent fusion routes, directly targeting SARS-CoV-2-containing vesicles to prevent spike-mediated fusion and viral escape [1]. Moreover, PLSCR1-knockout 36T-3 cells show significantly higher levels of human cytomegalovirus (HCMV) plaque formation and replication compared to parental cells, indicating that PLSCR1 negatively regulates HCMV replication [5]. In influenza A virus infection, Plscr1-/-mice are more susceptible to H1N1 SIV infection, suggesting its antiviral function in vivo [4].
In conclusion, PLSCR1 is a multifunctional gene playing essential roles in antiviral immunity, as demonstrated by gene-knockout models in the context of SARS-CoV-2, HCMV, and influenza A virus infections. It also has implications in other disease-related processes such as glaucoma-associated apoptosis of retinal ganglion cells, and the progression of basal-like breast cancer and acute myeloid leukemia [2,7,9]. The study of PLSCR1 using knockout models helps to understand its biological functions and provides insights into potential therapeutic strategies for related diseases.
