The Role Of Gsk-3Α Inhibition In Attenuating Lps-Induced Inflammation In Raw 264.7 Cells, Oluwaseyi Oyewole

Theses and Dissertations

Glycogen synthase kinase-3 (GSK-3), an enzyme that modulates glucose metabolism, has been recognized as an essential target in major inflammatory diseases based on its great specificity in substrate recognition. GSK-3β has been connected to cancer, obesity, liver diseases, and neurological diseases. Nonetheless, the other GSK-3 isoform, GSK-3α, is much less studied. Previous studies from our laboratory showed that inhibiting GSK-3α potentially confers an anti-inflammatory response when tested on microglia. However, little has been documented regarding the exact mechanism by which GSK-3α exerts its effect. One of the potential mechanisms involving its anti-inflammatory effect could be partially attributed to activating the …

Functional Analysis Of Ligand Binding Domain 2 Of Outer Surface Protein C Of Borreliella Burgdorferi, Gavin Z. Chambers

Theses and Dissertations

Lyme disease, caused by the spirochete Borreliella burgdorferi, is the most common vector-borne infection in North America. A critical determinant of early mammalian infection is outer surface protein C (OspC), a highly variable lipoprotein that is indispensable for spirochete survival but whose precise function remains unresolved. OspC has been proposed to mediate diverse roles, including complement evasion, adhesion, tissue dissemination, and antiphagocytic activity, supporting the view that it is a multifunctional virulence factor. Structural studies have identified two putative ligand-binding domains (LBD1 and LBD2), with LBD2 forming a solvent-exposed crown at the membrane-distal end of the OspC dimer.
