Thyroid hormones play vital roles in fetal brain development. Mutations in MCT8, recently recognised as a specific thyroid hormone transporter, define a novel syndrome of severe X-linked psychomotor retardation and thyroid hormone resistance.N-TERA-2 (NT2) cells (human embryonal cells with characteristics of CNS precursors) were transiently transfected with either WT MCT8 or its L471P, R271H or S448X mutations, described in males affected by severe psych...

Background: Hyperthyroidism is associated with an increased risk of atherothrombosis and venous thrombotic events by mechanisms that are not fully understood. Previous work has shown that blood clot structure determines the susceptibility to thrombosis and therefore the aim of this study was to investigate the effects of hyperthyroidism on clot structure and fibrinolysis.Methods: Six patients with hyperthyroidism were included in a pilot longitudinal stu...

Adipose tissue (AT) distribution impacts directly on type 2 diabetes and cardiovascular disease risk, however few studies have investigated the site-specific nature of human epicardial AT compared with gluteo-femoral (thigh) fat. Our recent studies have implicated epicardial AT as an important source of pro-inflammatory cytokines which may impact on myocardial function. Therefore the aim of this study was, using matched paired epicardial AT and gluteo-femoral (thigh) AT from p...

Research indicates that low testosterone is associated with CAD in men. Evidence suggests that men with hypotestosteronemia and concomitant CAD may benefit from physiological testosterone replacement therapy (PTRT). The mechanism by which testosterone produces these cardio-protective effects and the role of the androgen receptor remains largely unknown. The aim of this study was to determine whether testosterone modulates atheroma formation via its classical signalling ...

3-iodothyronamine (T1AM) is a novel, endogenous rapid acting biogenic amine, which is a potent agonist of the G-protein coupled trace amine-associated receptor 1, TAAR1. It has been suggested that endogenous T1AM could be generated by enzymatic deiodonation and decarboxylation of T4. The presence of T1AM in rat brain and the distribution of the TAAR1 receptor in the hypothalamus suggest that T1AM may affect food intake and regulate e...
