Mikel Haggadone

Immunology Program Graduate Student Candidate


Mike is a native Midwesterner and proud graduate of the University of Michigan, receiving his B.S. in Cellular and Molecular Biology in 2014. In addition to his scientific pursuits, Mike thoroughly enjoys teaching and engaging in student mentorship, participating in ultra-distance trail races to advocate for mental health, and enjoying Ann Arbor’s wonderful plant-based cuisine. After performing a brief stint of research in California, Mike enthusiastically returned to the University of Michigan in January 2016 to pursue his graduate work in immunology.

Research Interests

Since joining the Peters-Golden lab, Mike has been studying a subset of small, cell-derived structures called extracellular vesicles (EVs). In the lung, EVs secreted by the main tissue-resident immune cell, the alveolar macrophage (AM), contain anti-inflammatory cargoes that are acquired by surrounding epithelial cells. This mechanism is critical for the maintenance of lung homeostasis. While the functional importance of EVs has been defined in numerous contexts, the cellular and molecular determinants of EV cargo packaging remain poorly understood. As a result, Mike has begun to reveal novel mechanisms by which oxidative stress responses alter packaging of protein cargoes into AM-derived EVs. In addition to revealing how the immunoregulatory properties of EVs might be altered in the context of lung inflammation, Mike is also leveraging his findings to understand how EV protein cargo packaging occurs at the molecular level.
