Cell transplantation into immunodeficient mice has revolutionized our understanding of regeneration, stem cell self-renewal, and cancer; yet models for direct imaging of engrafted cells has been limited. Here, we characterize zebrafish with mutations in recombination activating gene 2 (rag2), DNA-dependent protein kinase (prkdc), and janus kinase 3 (jak3). Histology, RNA sequencing, and single-...
BACKGROUND/AIM Vaccination with fusions of dendritic cells (DCs) and mucin-1 (MUC1)-positive tumor cells (FC/MUC1) induces MUC1-specific antitumor immunity. However, little is known about the function of Cluster of Differentiation (CD)4 T-cells primed with FC/MUC1 in MUC1 transgenic (MUC1.Tg) mice. MATERIALS AND METHODS CD4 T-cells primed with FC/MUC1 were analyzed by flow cytometry. Antitumo...
In human-to-mouse xenograft models, reconstitution of human hematopoiesis is usually B-lymphoid dominant. Here we show that the introduction of homozygous Kit(Wv) mutations into C57BL/6.Rag2(null)Il2rg(null) mice with NOD-Sirpa (BRGS) strongly promoted human multi-lineage reconstitution. After xenotransplantation of human CD34(+)CD38(-) cord blood cells, these newly generated C57BL/6.Rag2(null)...
Macrophages were reported to be strong producers of interferon (IFN) after stimulation by interleukin 12 (IL-12) plus IL-18, which gave rise to a novel concept of autocrine macrophage activation. Here, we show that peritoneal exudate and bone marrowderived mouse macrophages generated by conventional techniquescontainsmallquantities of CD11b CD11c CD31 DX5 NK1.1 natural killer (NK) cells or CD3 ...
Thymic epithelial cells (TECs) help orchestrate thymopoiesis, and TEC differentiation relies on bidirectional interactions with thymocytes. Although the molecular mediators that stimulate medullary thymic epithelial cell (mTEC) maturation are partially elucidated, the signals that regulate cortical thymic epithelial cell (cTEC) homeostasis remain elusive. Using IL-7 reporter mice, we show that ...
Using normal and transgenic (Tg) mice, we have shown that peritoneal B-1 cells are activated by administration of cytokines or lipopolysaccharide and migrate to other lymphoid organs where they differentiate into antibody-secreting cells. However, little is known about the process of B-1 cell migration and differentiation in vivo. We developed a mouse line by crossing the antierythrocyte antibo...
