A Brief Discussion Of Gasdermin D'S Function In Multiple Sclerosis, Amie Brint
Arkansas Women in STEM Conference
Multiple Sclerosis (MS) is a neurodegenerative disease that particularly affects the nerves of the central nervous system (CNS). MS results in the degradation of the myelin sheath surrounding the axon, which is crucial for effective transmission of nerve signals. MS can be detected using lumbar punctures to look for elevated oligoclonal levels and using magnetic resonance imaging (MRI). The MRI can screen for plaques in the CNS, indicating the severity and probability of progression of the disease. Plaques are regions of nerves where the myelin has been removed from the nerves, preventing them from conducting the electrical signals necessary for …

The primary genetic risk determinant for late-onset Alzheimer's disease is the apolipoprotein E gene (APOE). Variations in this gene produce three different isoforms of the apolipoprotein E protein (ApoE): ApoE2, ApoE3, and ApoE4. ApoE# is the most common isoform, so rates of LOAD among other genotypes are indexed to this variant. ApoE2 is rather rare, but its carriers are less likely to get LOAD; when they do, they get it later. The second most common variant is ApoE4, and its carriers are significantly more likely to get LOAD. They also tend to succumb earlier. Once developed, LOAD is characterized by …
The Influence Of A Coiled-Coil Isoleucine Zipper On The Trimerization And Endosomolytic Activity Of The E5-Tat-Mcherry Protein, Valerie Nickel
The Influence Of A Coiled-Coil Isoleucine Zipper On The Trimerization And Endosomolytic Activity Of The E5-Tat-Mcherry Protein, Valerie Nickel
Honors Theses
The E5-TAT-mCherry protein is designed to initiate cellular uptake through endocytosis and react to the acidification of the endosomes by causing membrane lysis and cytosolic delivery. The cell penetrating peptide TAT from the HIV transcription activator binds to the cellular membrane and transports attached or coincubated cargo into the cell through endocytosis. E5 is a derivative of the fusogenic peptide HA2 from the influenza hemagglutinin protein and reacts to the acidification of the endosomal lumen by inserting into the membrane and increasing membrane permeability. The attached red fluorescent protein mCherry serves as a convenient biological probe for cell based assays. …
Solid Phase Peptide Synthesis, John Gibson
Solid Phase Peptide Synthesis, John Gibson
Honors Theses
Solid phase peptide synthesis is a relatively new biochemical process for polymerization of amino acids. It involves the selection of amino acids, blocking groups, and resins. This procedure was first investigated by R. B. Merrifield in an attempt to simplify previous methods of peptide synthesis. Since other methods involved amino acids, peptide esters, and diketopiperazines, peptide synthesis had been limited by amino acid selection and a host of technical problems. Solid phase synthesis alleviates many of these difficulties and limitations by supplying a faster and simpler stepwise addition of a wide variety of naturally occurring and synthetically prepared amino acids …
