Biomedical Engineering Undergraduate Honors Theses
Immune checkpoint blockade has demonstrated great potential in activating antitumor immunity. Ipilimumab is a monoclonal antibody which targets cytotoxic T-lymphocyte antigen-4. CTLA-4 belongs to the CD28 class of receptors and is found on the surface of CD4+ and CD8+ T cells. CTLA-4 acts to suppress the immune system when bound to CD80 and CD86 receptors on antigen presenting cells. Ipilimumab, or anti-CTLA-4, has shown to be effective in significantly extending the survival of patients with metastatic melanoma. However, systemic delivery of Ipilimumab also induces significant side effects such as: colitis, dermatitis, uveitis, and hypophysitis. In order to minimize …
