This Optimized Multicolor Immunofluorescence Panel was designed to identify and quantify all principal leukocyte populations in human blood using a minimum number of markers. We achieved this goal using a carefully selected combination of 14 surface markers compatible with standard flow cytometric instruments and accessible to a particularly large research community. Optimized for use in whole blood, this panel allows polymorphonuclear cell identification, supports live cell recovery, and is well-suited for absolute cell counting applications in the original in vivo volume. Panel performance and the separation of populations are high, and virtually no cells remain undefined after gating. Besides the identification of neutrophils, eosinophils, basophils, T cells, natural killer cells, B cells, plasma cells, monocytes, myeloid dendritic cells and plasmacytoid dendritic cells, this panel also covers progenitor cells and may therefore be attractive for stem cell researchers. Envisioned applications of this panel include immune monitoring within clinical trials, initial discovery to inform subset-targeted panels, and clinical diagnostics. In summary, this panel offers a broadly applicable platform for immune cell identification, quantification and characterization in human samples, particularly whole blood.

Background: Recent research has started to uncover an important connection between immune system activity and cognitive abilities. Although correlative associations have been documented, the causal mechanisms connecting specific immune cell subpopulations to cognitive capabilities remain insufficiently characterized. Our research aimed to determine directional relationships between distinct immune cell subtypes and cognitive function, potentially identifying targets for immunomodulatory interventions.

Background: Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative treatment for pediatric patients with hematologic malignancies. Human leukocyte antigen (HLA)-matched sibling donors (MSDs) are considered the optimal source for stem cell transplantation; however, up to 70% of patients lack an MSD. This disparity is particularly pronounced among racial and ethnic minorities, who face challenges in identifying matched unrelated donors (MUDs).

Fever-range whole-body hyperthermia (frWBH) is widely used as an adjunctive therapy for various conditions, including rheumatic diseases, psychiatric disorders, and cancer. Despite its extensive application, the biological and immunological mechanisms underlying frWBH remain poorly understood. To investigate the molecular mechanisms driving its therapeutic effects, we conducted a comprehensive analysis encompassing miRNA expression profiling using RT-qPCR, white blood cell (WBC) count assessment, and plasma proteomic profiling immediately following frWBH treatment.

Regulatory T cells are essential for immune homeostasis. While CD4 T cells are well characterized, CD8 T cells remain less understood and are primarily observed in pathological or experimental contexts. Here, we identify a naturally occurring CD8 regulatory precursor T cell at the steady state, defined by a CD8HLA-DRCD27 phenotype and a transcriptome resembling CD4 T cells.

NSG-SGM3 humanized mouse models are well-suited for studying human immune physiology but are technically challenging and expensive. We previously characterized a simplified NSG-SGM3 mouse, engrafted with human donor CD34 hematopoietic stem cells without receiving prior bone marrow ablation or human secondary lymphoid tissue implantation, that still retains human mast cell- and basophil-dependent passive anaphylaxis responses. Its capacities for human antibody production and human B cell maturation, however, remain unknown.
