BACKGROUND Birch allergy (BA) is a common pollinosis caused by the allergens Bet v 1, Bet v 2, and Bet v 4. Oral allergy syndrome (OAS) is frequently associated with BA. A gradient of sensitization to birch allergen across Europe has been reported. Therefore, this study aimed to investigate the birch sensitization profile, including OAS, across Italy. METHODS We performed a retrospective stud...

In this issue of the Journal, Dorfman and colleagues1 describe the usefulness of T-bet as a marker for specific subtypes of B-cell lymphoma. T-bet originally was identified as a T-box family transcription factor that dominantly programs CD4 and CD8 T-cell development along Th1 and Tc1 pathways, respectively.2 It accomplished this impressive task in part through the coordinated transcriptional a...

BET proteins are epigenetic readers whose deregulation results in cancer and inflammation. We show that BET proteins (BRD2, BRD3, BRD4 and BRDT) are globally similar with subtle differences in the sequences and structures of their N-terminal bromodomain. Principal component analysis and nonnegative matrix factorization reveal distinct structural clusters associated with specific BET family memb...

Displacement of Bromodomain and Extra-Terminal (BET) proteins from chromatin has promise for cancer and inflammatory disease treatments, but roles of BET proteins in metabolic disease remain unexplored. Small molecule BET inhibitors, such as JQ1, block BET protein binding to acetylated lysines, but lack selectivity within the BET family (Brd2, Brd3, Brd4, Brdt), making it difficult to disentang...

BACKGROUND Patients with chronic kidney disease (CKD) are associated with increased cardiovascular morbidity and mortality. An increase in the ratio of pre-ejection period (PEP) to ejection time (ET) is correlated with an increase in left ventricular mass index (LVMI) and a decrease in left ventricular ejection fraction (LVEF). Brachial PEP (bPEP) and brachial ET (bET) can be automatically dete...

During the adaptive phase of an immune response, naive B cells receive multiple signals to become activated. Among them are the engagement of the B cell Ag receptor and stimulation by cytokines. Specifically for an anti-microbial response, the recognition of viral or bacterial Ags by the BCR and the stimulation of IFN-gamma result in the predominant production of IgG2a. The T-bet protein has be...

Nitration of pollen derived allergens can occur by NO(2) and ozone in polluted air and it has already been shown that nitrated major birch (Betula verrucosa) pollen allergen Bet v 1.0101 (Bet v 1) exhibits an increased potency to trigger an immune response. However, the mechanisms by which nitration might contribute to the induction of allergy are still unknown. In this study, we assessed the e...

BACKGROUND/AIMS T-bet, a member of the T-box family of transcription factors, is a key marker of type I immune response within the tumor microenvironment, and has been previously reported by us to serve as an important prognostic indicator for human gastric cancer patients and a potential biomarker for immunotherapy. In the present study, we aimed to assess the clinical significance and prognos...

Bromodomain and extraterminal (BET) domain proteins have emerged as promising therapeutic targets in glioblastoma and many other cancers. Small molecule inhibitors of BET bromodomain proteins reduce expression of several oncogenes required for Glioblastoma Multiforme (GBM) progression. However, the mechanism through which BET protein inhibition reduces GBM growth is not completely understood. L...

BACKGROUND BET proteins (BRD2, BRD3, BRDT and BRD4) belong to the family of bromodomain containing proteins, which form a class of transcriptional co-regulators. BET proteins bind to acetylated lysine residues in the histones of nucleosomal chromatin and function either as co-activators or co-repressors of gene expression. An imbalance between HAT and HDAC activities resulting in hyperacetylati...
