The research of the Ainslie Lab is centered on immune-targeted therapies for the development of vaccines and treatment of infectious and autoimmune diseases. The Ainslie Lab is currently working on influenza vaccines including universal flu vaccines. Additionally, the lab does research on host cell-directed therapeutics for treatment of pathogenic infections including Salmonella enterica and Leishmania donovani. These therapies modulate the host environment to decrease pathogen burden and are thought to help mitigate the emergence of drug resistance as well as enhance the effect of conventional therapies against drug resistant pathogens. Finally, the lab has a focus on antigen specific therapies to treat autoimmune diseases, such as Multiple Sclerosis and Type 1 diabetes. Antigen specific treatments for autoimmune diseases suppress the immune response specifically, rather than universally suppressing the immune system, like many current therapies.

The Ainslie Lab focuses on the delivery of these vaccines and therapies, primarily using the degradable biopolymer acetalated dextran (Ac-DEX). By generating microparticles of Ac-DEX which encapsulate vaccine or therapeutic elements we can increase the efficacy of these agents. We use Ac-DEX because it has triggered release inside phagosomes of antigen presenting cells, facilities storage outside the cold-chain (i.e. refrigerators), and has unique tunable degradation rates. For example, using the tunable degradation rates of Ac-DEX microparticles as vaccine carriers, we have shown significantly affect both humoral and cellular responses to vaccines to better optimize these formulations. Moreover, we look to methods of scalable microparticle production to work towards less cost-limiting formulations.

Originally from Michigan, Dr. Ainslie received her bachelor of science in chemical engineering from Michigan State University and then earned both her master’s and Ph.D. in chemical engineering from Pennsylvania State University. She completed a postdoctoral fellowship at the University of California at San Francisco.
