Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Evaluation of target cell binding by an immunotherapeutic bispecific fusion protein, anti-CD3/chlorotoxin

Description
Engaging the immune system to attack neoplastic glial cells in the brain may be a promising approach to eliminate glioblastoma (GBM), a deadly form of primary brain cancer with low median survival. A bispecific fusion protein, anti-CD3/chlorotoxin (ACDClx), has been developed to engage cytotoxic T cells for destruction against GBM…

Engaging the immune system to attack neoplastic glial cells in the brain may be a promising approach to eliminate glioblastoma (GBM), a deadly form of primary brain cancer with low median survival. A bispecific fusion protein, anti-CD3/chlorotoxin (ACDClx), has been developed to engage cytotoxic T cells for destruction against GBM with little to no expected toxicity to surrounding healthy tissue. Previously, ACDClx has been demonstrated to induce calcium flux in T cells, indicating activation when cultured with GBM cells in vitro. Here, ACDClx fails to demonstrate successful binding to the CD3 domain of the T-cell receptor on CD4 T cells in vitro and fails to bind GBM cells despite demonstrated binding of chlorotoxin to the same cell line. This data warrants further investigation into the binding characteristics of ACDClx to target cells.
