The violin plot showed that sepsis patients had a higher proportion of plasma cells, regulatory T cells (Tregs), gamma delta T cells, monocytes, M0 macrophages, M1 macrophages, activated mast cells, eosinophils and neutrophils and a lower proportion of memory B cells, CD8 T cells, naïve CD4 T cells, resting memory CD4 T cells, resting NK cells and resting mast cells (Fig. 6A).
