Single-cell landscape of peripheral immune responses to fatal SFTS

Project description:We performed scRNA-seq on 27 PBMC samples from 15 SFTS patients (including four deceased and 11 surviving) and four healthy controls. We found that the immune cell landscape was reprogrammed in SFTS and characterized by monocyte shift to intermediate type along with complement activation, perturbation of plasmablasts composition, and highly exhausted T cells, all were correlated with lethal consequences. We identified the overexpression of interferon-stimulated genes across most immune cell types post SFTSV infection, which were simultaneously related to older age, high viremia and hyper-inflammation. These data collectively supported the intermediate monocytes and IFN-I-inducible plasmablasts to be major targets for SFTSV infection, and proposed the pivotal role of IFN-I response in exacerbating hyper-inflammation and lethal SFTS, which might help to identify therapeutic strategies for SFTS.

Molecular signatures of inflammatory profile and B-cell function in SFTS patients

Project description:Severe fever with thrombocytopenia syndrome banyangvirus (SFTSV) induces immunopathogenic disease with high fatality rate. Despite serious health concern, the mechanisms underlying clinical manifestations are largely unknown. Here, we applied targeted proteomics and single-cell transcriptomics analyses to examine the differential immune landscape of SFTS patient blood. Serum immunoprofiling distinguished Low-risk and High-risk clusters of SFTS patients with differential inflammatory cytokine levels, which matched with disease severity. Single-cell transcriptomics analysis of SFTS patient blood at different infection state showed pronounced expansion of B cells with the alteration of B-cell subset populations, specifically in fatal patients. Furthermore, plasma cells were the primary reservoir of SFTSV replication with the downregulation of IFN pathway. This study identifies not only the molecular signatures of serum inflammatory profile and B cell lineage population, but also plasma cells as the viral reservoir in SFTSV-induced fatal patients, suggesting the alteration of B cell function linked to SFTS lethal infection.

Transcriptome profiles characteristics of peripheral immune in Severe Fever with Thrombocytopenia Syndrome patients

Project description:To investigate the response mechanisms of Severe fever with thrombocytopenia syndrome (SFTS) patients, we conducted transcriptomic analysis of peripheral immunity in 14 SFTS patients, ranging from modal infection to severe and fatal disease. Our results observed the potential mechanism for the heterogeneity of clinical symptoms, which can further elucidate the interaction between viruses and hosts and contribute to clinical treatment.

Analysis of SFTS pathogenesis based on single-cell RNA sequencing of monocytes

Project description:Severe fever with thrombocytopenia syndrome (SFTS) is a newly identified tick-borne viral disease with a high mortality rate. Monocytes are known to play an important role in the pathogenesis of SFTS, but the distinct subpopulations of monocytes associated with the disease progression and their roles in inflammatory responses remain poorly elucidated. In this study, we used single-cell RNA sequencing (scRNA-seq) to explore the specific monocyte subpopulations correlated with the progression of SFTS and their involvement in inflammatory processes.

Identification of immune correlates of fatal outcomes in critically ill COVID-19 patients

Project description:Single-cell RNA-sequencing reveals a shift from focused IFN alpha-driven signals in COVID-19 ICU patients who survive to broad pro-inflammatory responses in fatal COVID-19 – a feature not observed in severe influenza. We conclude that fatal COVID-19 infection is driven by uncoordinated inflammatory responses that drive a hierarchy of T cell activation, elements of which can serve as prognostic indicators and potential targets for immune intervention.

Preexisting chronic conditions for fatal outcome among SFTS patients: An observational Cohort Study.

Project description:Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that is caused by a novel bunyavirus SFTSV. Currently our knowledge of the host-related factors that influence the pathogenesis of disease is inadequate to allow prediction of fatal outcome. Here we conducted a prospective study of the largest database on the SFTS patients, to identify the presence of comorbidities in SFTS, and estimate their effect on the fatal outcome. Among 2096 patients eligible for inclusion, we identified nine kinds of comorbidities, from which hyperlipidemia (12.2%; 95% CI: 10.8%-13.6%), hypertension (11.0%; 95% CI: 9.6%-12.3%), chronic viral hepatitis (CVH) (9.3%; 95% CI: 8.1%-10.5%), and diabetes mellitus (DM) (6.8%; 95% CI: 5.7%-7.9%) were prevalent. Higher risk of death was found in patients with DM (adjusted OR = 2.304; 95% CI: 1.520-3.492; P<0.001), CVH (adjusted OR = 1.551; 95% CI: 1.053-2.285; P = 0.026) and chronic obstructive pulmonary diseases (COPD) (adjusted OR = 2.170; 95% CI: 1.215-3.872; P = 0.009) after adjusting for age, sex, delay from disease onset to admission and treatment regimens. When analyzing the comorbidities separately, we found that the high serum glucose could augment diseases severity. Compared to the group with max glucose < 7.0 mmol/L, patients with glucose between 7.0-11.1 mmol/L and glucose ≥11.1 mmol/L conferred higher death risk, with the adjusted OR to be 1.467 (95% CI: 1.081-1.989; P = 0.014) and 3.443 (95% CI: 2.427-4.884; P<0.001). Insulin therapy could effectively reduce the risk of severe outcome in DM patients with the adjusted OR 0.146 (95% CI: 0.058-0.365; P<0.001). For CVH patients, severe damage of liver and prolongation of blood coagulation time, as well as high prevalence of bleeding phenotype were observed. These data supported the provocative hypothesis that treating SFTS related complications can attain potentially beneficial effects on SFTS.
