Functional Characterization Of The C-Terminal Cholinesterase-Like (Chel) Domain Of The Thyroid Hormone Precursor Protein, Berenice Morales-Rodriguez

Pharmaceutical Sciences (MS) Theses

Vertebrate life is unsustainable without thyroid hormones. The only known precursor for thyroid hormone synthesis is thyroglobulin (Tg), composed of upstream regions I-II-III and a C-terminal cholinesterase-like (ChEL) domain, which bears 47% similarity to acetylcholinesterase (AChE). Mutations in Tg cause congenital hypothyroidism, the most common congenital endocrinopathy affecting 1 in 2,000-4,000 newborns, with a varying degree of phenotypic manifestations. Tg protein, regulated by TSH, is secreted to the lumen of thyroid follicles, where thyroxine (T₄) is formed primarily at the N-terminus, and triiodothyronine (T₃) is formed primarily in the ChEL domain. Previous in vitro studies indicated …

The Impact Of Cocaine On Inflammatory Markers In Sim-A9 Microglial Cells, Tyler Vaglivelo

Honors Scholar Theses

Substance use disorders are conditions in which an individual continues to use a drug or other substance despite adverse consequences to their health and well-being. It has been hypothesized that inflammation within the central nervous system plays a critical role in the development of substance use disorders. The resident macrophages in the brain, also known as microglia, release markers of inflammation in response to injury or infection. A better understanding of the inflammatory response mediated by microglia in response to drugs of misuse can validate this hypothesis and help guide drug development. In the current studies, the microglia cell line …
