We studied T-bet expression in 91 cases of peripheral T-cell lymphoma (PTCL) by immunostaining and found expression in 42 cases (46%), including all 5 lymphoepithelioid lymphoma cases and 12 (86%) of 14 angioimmunoblastic lymphoma cases, but only 9 (25%) of 36 anaplastic large cell lymphoma cases. Expression of T-bet in PTCL correlates with expression of other markers of Th1 T-cell differentiat...

The bromodomain and extra terminal (BET) family of bromodomains have been the focus of extensive research, leading to the development of many potent, selective chemical probes and recent clinical assets. The profound biology associated with BET bromodomain inhibition has provided a convincing rationale for targeting bromodomains for the treatment of disease. However, the BET family represents j...

Th1 and Th17 cells are involved in the pathogenesis of rheumatoid arthritis (RA). T-bet, a Th1-specific transcription factor, appears to drive the maturation of Th1 and IFN-γ secretion. In the present study, we established the T-bet shRNA recombinant plasmid (p-T-shRNA) and explored its possible anti-inflammatory effect in a collagen-induced arthritis (CIA) model by local injection of plasmid v...

IFN-gamma is well known as the signature cytokine of CD4+ T helper 1, CD8+, and natural killer cells, but recent studies demonstrate that antigen-presenting cells, in particular dendritic cells (DCs), are another potent source for this proinflammatory cytokine. T-bet, a transcription factor that controls IFN-gamma expression in CD4+ T cells, was reported recently to be expressed in human monocy...

Upon detection of antigen, CD4(+) T helper (Th) cells can differentiate into a number of effector types that tailor the immune response to different pathogens. Alternative Th1 and Th2 cell fates are specified by the transcription factors T-bet and GATA-3, respectively. Only a handful of target genes are known for these two factors and because of this, the mechanism through which T-bet and GATA-...

A well-defined poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA-b-C60) was synthesized using the atom transfer radical polymerization (ATRP) technique and betainized with 1,3-sulfobetaine to yield a Bet-PDMAEMA-b-C60. The solution properties were then studied by light transmittance, viscometric, 1H NMR laser light scattering, and transmission electron macroscopic techniques. It was found that...

Preeclampsia is a leading cause of maternal and fetal morbidity/mortality; however, the pathophysiological mechanisms are unclear. Vascular endothelial dysfunction in preeclampsia has been partially attributed to changes in endothelin-1 (ET-1). Several enzymes, including matrix metalloproteinases (MMPs; particularly MMP-2), cleave the inactive precursor big ET-1 (bET-1) to active ET-1. Notably,...
