Abstract
Introduction Memory T (Tm) cells are a subpopulation of immune cells with great heterogeneity. Part of this diversity came from T cells that were primed with different viruses. Understanding the differences among different viral-specific Tms will help develop new therapeutic strategies for viral infections. Methods In this study, we compared the transcriptome of Tm cells that primed with CMV, EBV and SARS-CoV-2 with single-cell sequencing and studied the similarities and differences in terms of subpopulation composition, activation, metabolism and transcriptional regulation. Results We found that CMV is marked by plentiful cytotoxic Temra cells, while EBV is more abundant in functional Tem cells. More importantly, we found that CD28 and CTLA4 can be used as continuous indicators to interrogate the antiviral ability of T cells. Furthermore, we proposed that REL is a main regulatory factor for CMV-specific T cells producing cytokines and plays an antiviral role. Discussion Our data gives deep insight into molecular characteristics of Tm subsets from different viral infection, which is important to understand T cell immunization. Furthermore, our results provide basic background knowledges for T cell based vaccine development in future.

Abstract
OBJECTIVE We evaluated the hypothesis that ovarian cancer patients have significantly higher levels of serum macrophage migration inhibitory factor (MIF). STUDY DESIGN MIF levels were determined by enzyme-linked immunosorbent assay (ELISA) in epithelial ovarian cancer cell lines and immortalized normal ovarian surface epithelial cells and in serum of ovarian cancer patients (n = 54) and age-matched healthy women (n = 60). To determine the impact of Toll-like receptor-4 ligation on MIF levels, cells were treated for 48 hours with lipopolysaccharide. RESULTS Cancer cells, but not normal cells, secrete significant amounts of MIF. This correlates in vivo, where serum MIF levels are significantly higher in ovarian cancer patients. Treatment of cancer cells with lipopolysaccharide induced a significant increase in MIF secretion. CONCLUSION MIF may be relevant in the process of ovarian cancer formation and progression. The events leading to the induction of MIF expression and its contribution to ovarian cancer progression may open new venues for targeted therapy.
