My project in the Eisenlohr lab focuses on understanding the pieces of proteins from the flu virus, called epitopes, that can activate immune cells called T-cells. Understanding what epitopes can activate T-cells is important for developing more effective vaccines for infectious diseases and for improving treatments for cancer and autoimmune diseases. To investigate the sources of these epitopes, we infected a mouse cell line with flu virus. We then used a technique called mass spectrometry to identify different epitopes, including one from a region of the flu genome that is not normally thought to be translated into a protein. Through my project, I have learned more about the intricacies of the immune system and about innovative immunological research techniques. I am excited to continue conducting research in the lab to further understand how these epitopes are presented to the immune system.
