Cre recombinase toxicity is dependent on the level of Cre activity and may also interfere with cell proliferation. Here, we compared two different published tamoxifen-inducible CD4-CreERT2 mouse lines for their suitability to study the dynamics of T-follicular helper cell responses in vivo. Our data underscore that under certain circumstances inducible Cre toxicity (tamoxifen application results in translocation of preformed CreERT2 to the nucleus) interferes with cell survival and, therefore, necessitates careful interpretation of experimental data and the inclusion of appropriate controls. Interestingly, our data indicate that low expression of CreERT2 can still allow for efficient recombination in proliferating lymphocytes without causing excessive cell loss due to Cre toxicity. © 2020 The Authors.

Abnormalities in microRNA (miRNA) expression are related to excessive IFN production, however the role of miRNA remains largely elusive in SSc monocytes. This study explores global miRNA-mRNA profiling of SSc monocytes and functional attenuation of IFN and ISGs by specific miRNAs. Global sequencing of mRNA (mRNA-seq) and miRNA (miRNA-seq) samples were performed simultaneously on healthy controls and SSc monocytes. Following computational analysis, selected miRNAs-mRNA candidates were validated, correlated with clinical parameters, and tested by functional assays. Transcriptomics data and qPCR analysis confirmed
