This is an update to the Guidelines for the Use of Flow Cytometry and Cell Sorting in Immunological Studies (Third Edition), Chapter 12C, by Cossarizza et al. A 38-marker full-spectrum flow cytometry panel enabling high-resolution profiling of human γδ T cells across blood and lymphoid tissues, including robust identification of rare, tissue-adapted subsets.

Allergic reaction-derived IL-33 activates ST2 to trigger selective eosinophil activation. IL-33 in a type 2 immune response environment induces biogenesis of lipid bodies in eosinophils, platforms for the generation of lipid mediators, and selectively triggers LTC4 production. ABSTRACT Like pieces of a puzzle, IL-33, eosinophils, and cysteinyl leukotrienes seem to come together and orchestrate allergic … Read more

Our cover features images related to flow cytometry techniques widely used for analysis of function and phenotypes of major human and murine immune cell subsets, superimposed on a multidimensional immune cell population scatter plot. These images are taken from the third edition of EJI’s Flow Cytometry Guidelines by Cossarizza et al., a comprehensive resource prepared … Read more

The CD40-CD40L pathway is often dysregulated in B-cell-driven autoimmune diseases, making the development of CD40L inhibitors a promising therapeutic approach in managing autoimmune responses. We developed an inhibitory anti-CD40L Fab fragment, Fab20, and demonstrated that Fab20 effectively suppresses B-cell proliferation, differentiation, and antibody production in vitro. Made with Biorender. ABSTRACT Dysregulation of the CD40-CD40L axis … Read more

We developed a 50-plex imaging protocol using the MACSima platform to characterize the microarchitecture of germinal centers in secondary lymphoid tissues. This workflow combines tissue processing, automated cyclic imaging, image preprocessing, and a new analysis method that detects morphological changes in irregularly shaped stromal cells.

Human lamina propia mononuclear cells (LPMC) were isolated from intestinal biopsies and resections, as well as peripheral blood mononuclear cells (PBMC) from blood. Using flow cytometry approaches, we characterized cDC subsets and assessed their functional capacity through T-cell coculture assays (after isolation of the different subsets of cDC using sorter cytometry). This approach enabled a … Read more

1. Normal state: T-cell-endogenous IL-6 stabilizes IL6R and promotes STAT3 activation, functional Th17 differentiation with resistance to immune suppression. 2. Il6-KO: Loss of T-cell endogenous IL-6 destabilizes IL6R expression, leading to suboptimal Th17 and greater susceptibility to suppression, despite availability of exogenous IL-6. 3. IL-21 bypasses the requirement for endogenous IL-6 by restoring STAT3 signaling … Read more

EBV latent and lytic genes uniquely contribute to Multiple Sclerosis development by various immunopathogenic mechanisms in susceptible hosts. Briefly, EBV infection shapes the B-cell repertoire and promotes the oligoclonal expansion and subsequent CNS infiltration of T-bet+CXCR3+ B cells, resulting in a cascade of immune dysregulation, CNS inflammation, and autoreactive T cell stimulation. Created in BioRender. … Read more

Chemical library screening identified lomitapide as a novel mast cell (MC) regulatory agent. Lomitapide selectively inhibits IgE/Ag- or phorbol 12-myristate 13-acetate (PMA)/ionomycin-mediated MC degranulation by altering plasma membrane dynamics, including endocytosis and membrane fusion. ABSTRACT Allergic diseases are a global health concern, and new molecular insights and therapeutic agents are necessary to support future research … Read more
