TSHR autoantibodies with stimulating (agonist) activity cause the hyperthyroidism of Graves’ disease, while the rarer blocking (antagonist) type TSHR autoantibodies are responsible for hypothyroidism in some patients. We have isolated four human monoclonal autoantibodies (MAbs) which bind the TSHR with high affinity. Two antibodies, M22 and K1-18 have potent thyroid stimulating activity, one MAb K1-70 has strong antagonist (blocking) activity and the fourth MAb 5C9 has st...

The ACE I/D polymorphism is associated with resting ACE activity such that DD>ID>II. The D allele is strongly associated with increased exercise-induced left ventricular hypertrophy (LVH) and cardiovascular risk.Objective: Examine the relation between ACE genotype, exercise, circulating ACE and angiotensin II.Ethical approval was obtained and 17 (9DD, 8II) healthy, male (22.9+/-1.9 years, 178.6+/-2.8cm, 71.9+/-2.2kg) Caucasi...
