Background: In coeliac disease (CD) mucosa, the histological lesion is associated with marked infiltration of T helper cell type 1 (Th1) cells. However, the molecular mechanisms which regulate Th1 cell differentiation in CD mucosa are unknown. Aims: To analyse expression of transcription factors which control the Th1 cell commitment in CD. Patients: Duodenal mucosal samples were taken from untr...
The polarization of CD4+ T cells into distinct T helper cell lineages is essential for protective immunity against infection, but aberrant T cell polarization can cause autoimmunity. The transcription factor T-bet (TBX21) specifies the Th1 lineage and represses alternative T cell fates. Genome-wide association studies have identified single nucleotide polymorphisms (SNPs) that may be causative ...

Valpha14i natural killer T (NKT)-cell function has been implicated in a number of disease conditions. The molecular events that drive Valpha14i NKT-cell development remain elusive. We recently showed that T-bet is required for the terminal maturation of these cells. Here we identify some of the genetic targets of T-bet during Valpha14i NKT-cell lineage development. Microarray gene-expression an...
V 14i natural killer T (NKT)–cell function has been implicated in a number of disease conditions. The molecular events that drive V 14i NKT-cell development remain elusive. We recently showed that T-bet is required for the terminal maturation of these cells. Here we identify some of the genetic targets of T-bet during V 14i NKT-cell lineage development.

Although Th1, Th2, and Th17 cells are thought to be major effector cells in adaptive alloimmune responses, their respective contribution to allograft rejection remains unclear. To precisely address this, we used mice genetically modified for the Th1 and Th17 hallmark transcription factors T-bet and RORγt, respectively, which allowed us to study the alloreactive role of each subset in an experim...
Many chronic infections, including malaria and HIV, are associated with a large expansion of CD21-CD27- 'atypical' memory B cells (MBCs) that exhibit reduced B cell receptor (BCR) signaling and effector functions. Little is known about the conditions or transcriptional regulators driving atypical MBC differentiation. Here we show that atypical MBCs in malaria-exposed individuals highly express ...
