Human BDCA3+ dendritic cells (DCs) were suggested to be homologous to mouse CD8alpha+ DCs. We demonstrate that human BDCA3+ DCs are more efficient than their BDCA1+ counterparts or plasmacytoid DCs (pDCs) in cross-presenting antigen and activating CD8+ T cells, which is similar to mouse CD8alpha+ DCs as compared with CD11b+ DCs or pDCs, although with more(More)
Trail(+)DX5(-)Eomes(-) natural killer (NK) cells arise in the mouse fetal liver and persist in the adult liver. Their relationships with Trail(-)DX5(+) NK cells remain controversial. We generated a novel Eomes-GFP reporter murine model to address this question. We found that Eomes(-) NK cells are not precursors of classical Eomes(+) NK cells but rather(More)
TLR have a crucial role in the detection of microbial infection in mammals. Until recently, most investigations on TLR have focused on cells of the innate immune system and on the role of TLR in the initiation of antigen-specific responses following recognition of microbial products by APC. Here, we report that murine T cells express TLR1, TLR2, TLR6, TLR7(More)
The mouse inbred line C57BL/6J is widely used in mouse genetics and its genome has been incorporated into many genetic reference populations. More recently large initiatives such as the International Knockout Mouse Consortium (IKMC) are using the C57BL/6N mouse strain to generate null alleles for all mouse genes. Hence both strains are now widely used in(More)
Transcription factor Sp1 has recently been shown to be overexpressed in a number of human cancers and its overexpression contributes to malignant transformation. Sp1 regulates the expression of a number of genes participating in multiple aspects of tumorigenesis such as angiogenesis, cell growth and apoptosis resistance. To better understand the role of(More)
BACKGROUND The ubiquitous transcription factor Sp1 regulates the expression of a vast number of genes involved in many cellular functions ranging from differentiation to proliferation and apoptosis. Sp1 expression levels show a dramatic increase during transformation and this could play a critical role for tumour development or maintenance. Although Sp1(More)
The characteristics of CD8+ T cells responsible for memory responses are still largely unknown. Particularly, it has not been determined whether different activation thresholds distinguish naive from memory CD8+ T cell populations. In most experimental systems, heterogeneous populations of primed CD8+ T cells can be identified in vivo after immunization.(More)
The transcription activator c-Myb is expressed at high levels in immature thymocytes and during T-cell activation and may be a regulator of T-cell differentiation. To investigate the role of c-Myb in T-cell development, we generated transgenic mice in which two dominant interfering Myb alleles, one a competitive inhibitor of DNA binding, and the other, an(More)
comitant chemotherapy and rituximab.2 The study by Dunleavy et al, also reported in this issue, has again confirmed the efficacy of rituximab, allowing an abbreviated course of infusional EPOCH while noting no treatmentrelated deaths or new opportunistic infections. Whereas it behooves the clinician to be aware of the potential for rituximab-related(More)
