Efforts to limit GVHDmediated by alloreactive donor T cells after allogeneic bonemarrow transplantation are limited by a concomitant decrease in graft-versus-tumor (GVT) activity and increased possibilities of tumor relapse. Using a novel approach, we adoptively transferred conventional T cells expressing the transcription factor promyelocytic leukemia zinc finger (PLZF), which confers effector...
The proto-oncogenic properties of the POK family of transcriptional repressors BCL6, PLZF, and LRF have been well established. These proteins utilize their amino-terminal POZ domains for multimerization and the recruitment of co-repressors. Because LRF represses the production of the tumor suppressor p19(Arf) (ARF), it is regarded as an attractive therapeutic target for the treatment of many ty...
Peripheral T-cell lymphomas (PTCL) are uncommon and account for ,10%of all non-Hodgkin lymphomas. Themost common category of PTCL is “not otherwise specified” (PTCL-NOS), reflecting the lack of specific parameters to define PTCL subsets in a biologically relevant way. Although it is recognized that PTCL arise from both adaptive and innate lymphoid cells, the precise cell of origin for most PTCL...
A large fraction of innate NKTγδ T cells uses TCRs composed of a semi-invariant Vδ6.3/6.4-Dδ2-Jδ1 chain together with more diverse Vγ1-Jγ4 chains. To address the role of γδTCR specificity in their generation, we analyzed their development in mice transgenic (Tg) for a Vγ1-Jγ4 chain frequently expressed by NKTγδ cells (Tg-γ) and in mice Tg for the same Vγ1-Jγ4 chain together with a Vδ6BDδ2Jδ1 ch...
Aldosterone is the principal regulator of Na homeostasis, and thereby blood pressure. One of the main targets of aldosterone is the epithelial Na channel (ENaC) located in the apical membrane of target cells. Previous studies identified several genes involved in the regulation of ENaC such as SGK1; however, SGK1 knockout mice have only a mild salt-losing phenotype, indicating that further genes...
Rare CD1d-α-galactosylceramide-specific T cells that do not express the invariant Vα24 chain of human NKT cells were recently identified after expansion in vitro with the lipid Ag, but their phenotype and frequency in vivo and lineage relationship with NKT cells could not be elucidated. By using a CD1d tetramer-based method to enrich these cells from fresh peripheral blood, we demonstrated thei...
Distinct classes of neurons and glial cells in the developing spinal cord arise at specific times and in specific quantities from spatially discrete neural progenitor domains. Thus, adjacent domains can exhibit marked differences in their proliferative potential and timing of differentiation. However, remarkably little is known about the mechanisms that account for this regional control. Here, ...
BACKGROUND The spermatogonial stem cell (SSC) pool in the testes of non-human primates is poorly defined. METHODS To begin characterizing SSCs in rhesus macaque testes, we employed fluorescence-activated cell sorting (FACS), a xenotransplant bioassay and immunohistochemical methods and correlated our findings with classical descriptions of germ cell nuclear morphology (i.e. A(dark) and A(pale...
The (pro)renin receptor [(P)RR] is crucial for cardio-renal pathophysiology. The distinct molecular mechanisms of this receptor are still incompletely understood. The (P)RR is able to interact with different signalling proteins such as promyelocytic leukemia zinc finger protein (PLZF) and Wnt receptors. Moreover, domains of the (P)RR are essential for V-ATPase activity. V-ATPase- and Wnt-mediat...
Acute promyelocytic leukemia (APL) is associated with chromosomal translocations, invariably involving the retinoic acid receptor alpha (RAR alpha) gene fused to one of several distinct loci, including the PML or PLZF genes, involved in t(15;17) or t(11;17), respectively. Patients with t(15;17) APL respond well to retinoic acid (RA) and other treatments, whereas those with t(11;17) APL do not. ...
