Abstract G protein-coupled receptors (GPCRs) represent the largest group of cell surface receptors and an important pharmacological target. Though originally thought to act in a one receptor-one effector fashion, it is now known that these receptors are capable of oligomerization and can function as dimers or higher order oligomers in ...

Antagonists of tumor necrosis factor alpha (TNFa) have revolutionized the treatment of selected inflammatory diseases. Recombination Camelidae variable heavy-chain domain-only TNFa antibodies (anti-TNF-V(H)H) have been developed to antagonize the action of human and murine TNFa. Here, we describe a strategy to obtain functional covalent dimer anti-TNF-V(H)H molecules with the C-terminal ...

INTRODUCTION: Video-assisted thoracoscopic surgery is widely used for resecting early-stage non-small cell lung cancer. Segmentectomy and subsegmentectomy require a thorough knowledge of the 3-D bronchovascular anatomy of the lung. Previously, our department reported using a 3-D pulmonary model of a patient for thoracoscopic surgical treatment of non-small cell lung cancer. ...

Serine protease inhibitors (serpins) are evolutionary old, structurally conserved molecules which encompass nearly all branches of life. More than 1,000 serpins were characterized to date which are subdivided into 16 subgroups (A-P) according to their common ancestry; among them, 37 are found in humans. Serpins were termed after their capability ...

Human essential hypertension is partly caused by genetic factors. Angiotensinogen (AGT), G-protein β3-subunit (GNB3) and cytochrome P450 3A5 (CYP3A5) are candidate hypertension susceptibility genes and risk alleles at these loci have been thought to arise owing to human adaptation to climatic changes following the migration out-of-Africa. This study aimed to ...

Long-lasting memories require specific gene expression programmes that are, in part, orchestrated by epigenetic mechanisms. Of the epigenetic modifications identified in cognitive processes, histone acetylation has spurred considerable interest. Whereas increments in histone acetylation have consistently been shown to favour learning and memory, a lack thereof has been causally implicated ...
