In patients infected by SARS-CoV-2 who experience an exaggerated inflammation leading to pneumonia, monocytes likely play a major role but have received poor attention. Thus, we analyzed peripheral blood from with COVID-19 pneumonia and found that these cells show signs of altered bioenergetics mitochondrial dysfunction, had reduced basal maximal respiration, spare respiratory capacity, decreased proton leak. Basal extracellular acidification rate was also diminished, suggesting capability perform aerobic glycolysis. Although ability oxidative burst, they were still capable producing TNF IFN-γ in vitro. A significantly high amount depolarized mitochondria abnormal ultrastructure. redistribution monocyte subsets, significant expansion intermediate/pro-inflammatory cells, amounts immature found, along concomitant compression classical monocytes, increased expression inhibitory checkpoints like PD-1/PD-L1. High plasma levels several inflammatory cytokines chemokines, including GM-CSF, IL-18, CCL2, CXCL10, osteopontin, finally confirm the importance immunopathogenesis.

Single-cell RNA sequencing (scRNA-seq) has become an empowering technology to profile the transcriptomes of individual cells on a large scale. Early analyses differential expression have aimed at identifying differences between subpopulations identify subpopulation markers. More generally, such methods compare levels across sets cells, thus leading cross-condition analyses. Given emergence replicated multi-condition scRNA-seq datasets, area increasing focus is making sample-level inferences, termed here as state analysis; however, it not clear which statistical framework best handles this situation. Here, we surveyed perform analyses, including cell-level mixed models and based aggregated pseudobulk data. To evaluate method performance, developed flexible simulation that mimics multi-sample We analyzed data from mouse cortex uncover subpopulation-specific responses lipopolysaccharide treatment, provide robust tools for analysis within muscat R package.

Abstract The third edition of Flow Cytometry Guidelines provides the key aspects to consider when performing flow cytometry experiments and includes comprehensive sections describing phenotypes functional assays all major human murine immune cell subsets. Notably, contain helpful tables highlighting differences between cells. Another useful feature this is analysis clinical samples with examples applications in context autoimmune diseases, cancers as well acute chronic infectious diseases. Furthermore, there are detailing tips, tricks pitfalls avoid. All written peer‐reviewed by leading experts immunologists, making an essential state‐of‐the‐art handbook for basic researchers.

Treatment of severe COVID-19 is currently limited by clinical heterogeneity and incomplete description specific immune biomarkers. We present here a comprehensive multi-omic blood atlas for patients with varying severity in an integrated comparison influenza sepsis versus healthy volunteers. identify signatures correlates host response. Hallmarks disease involved cells, their inflammatory mediators networks, including progenitor cells myeloid lymphocyte subsets, features the repertoire, acute phase response, metabolism, coagulation. Persisting activation involving AP-1/p38MAPK was feature COVID-19. The plasma proteome enabled sub-phenotyping into patient clusters, predictive outcome. Systems-based integrative analyses tensor matrix decomposition all modalities revealed groupings linked specificity compared to sepsis. Our approach will support future drug development, trial design, personalized medicine approaches

Abstract Relatlimab and nivolumab combination immunotherapy improves progression-free survival over monotherapy in patients with unresectable advanced melanoma 1 . We investigated this regimen resectable clinical stage III or oligometastatic IV (NCT02519322). Patients received two neoadjuvant doses (nivolumab 480 mg relatlimab 160 intravenously every 4 weeks) followed by surgery, then ten of adjuvant therapy. The primary end point was pathologic complete response (pCR) rate 2 resulted 57% pCR 70% overall among 30 treated. radiographic using Response Evaluation Criteria Solid Tumors 1.1 57%. No grade 3–4 immune-related adverse events were observed the setting. 1- 2-year recurrence-free 100% 92% for any response, compared to 88% 55% who did not have a ( P = 0.005). Increased immune cell infiltration at baseline, decrease M2 macrophages during treatment, associated response. Our results indicate that induces high rate. Safety therapy is favourable other regimens. These data, RELATIVITY-047 trial , provide further confirmation efficacy safety new regimen.

Abstract Glioblastoma multiforme (GBM) is the most common and aggressive form of primary brain cancer, for which effective therapies are urgently needed. Chimeric antigen receptor (CAR)-based immunotherapy represents a promising therapeutic approach, but it often impeded by highly immunosuppressive tumor microenvironments (TME). Here, in an immunocompetent, orthotopic GBM mouse model, we show that CAR-T cells targeting tumor-specific epidermal growth factor variant III (EGFRvIII) alone fail to control fully established tumors but, when combined with single, locally delivered dose IL-12, achieve durable anti-tumor responses. IL-12 not only boosts cytotoxicity cells, also reshapes TME, driving increased infiltration proinflammatory CD4 + T decreased numbers regulatory (Treg), activation myeloid compartment. Importantly, immunotherapy-enabling benefits achieved minimal systemic effects. Our findings thus local delivery may be adjuvant cell therapy GBM.
