Thyroid hormones are synthesized within the thyroglobulin (Tg) molecule and must be released to reach the circulation and exert their metabolic effect. We have previously shown that three lysosomal endopeptidases, cathepsin B, D, and L, are active in the early stages of intrathyroidal degradation of Tg but do not themselves release free hormone. The current(More)
The urinary iodine is the best laboratory measure of iodine nutrition. Several simple methods are suitable for developing countries. The present article reviews these briefly. It also presents preliminary information on "Fast B", a rapid method that puts samples into convenient ranges rather than giving absolute values for individuals. This grouping by(More)
Identification of Mycobacterium tuberculosis proteins that can provide immunological protection against tuberculosis is essential for the development of a more effective vaccine. To identify new vaccine targets, we have used immunoaffinity chromatography to isolate class I HLA-A*0201-peptide complexes from M. tuberculosis-infected cells and sequenced the(More)
We studied thyroid tissue from two siblings with Pendred's syndrome (familial goiter and congenital deafness), both with the Mondini-type inner ear malformation, goiter, and hypothyroidism. Iodine trapping and peroxidase levels were grossly normal. Thyroglobulin (Tg), the only iodoprotein found, had a normal monomer size (330 kilodaltons), but low content(More)
The thyroid couples two iodotyrosine molecules to produce thyroid hormone at the acceptor site in thyroglobulin, leaving dehydroalanine or pyruvate at the donor position. Previous work has located the acceptors but not the principal iodotyrosine donors. We incorporated [14C]tyrosine into beef thyroid slices, isolated and iodinated the [14C]thyroglobulin (Tg(More)
Identifying naturally occurring peptides bound to HLA class I molecules recognized by HLA-restricted cytotoxic T lymphocytes (CTL) is both relevant and central to the development of effective immunotherapeutic strategies against cancer. Several cancer-related genes have been reported for ovarian cancer, but very few are known to be naturally processed T(More)
