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 with High Honors and High Distinction. 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-secreted structures called extracellular vesicles (EVs). In the lung, EVs released by the main tissue-resident immune cell, the alveolar macrophage, are concentrated with anti-inflammatory molecules that are taken up by surrounding epithelial cells, which is important for keeping inflammation at bay. From the perspective of a basic biologist, this is also a fascinating phenomenon because it suggests that over time, these two cell types have evolved to depend on one another for generating, secreting, and acquiring homeostatic information that is concentrated in little vesicular packages. However, while the functional importance of these EVs is known, very little is known about how molecular information is specifically concentrated (i.e., sorted) into EVs, which remains a major gap in knowledge in the field. Mike’s thesis work has focused on how the interplay between cell stress responses and metabolic alterations in alveolar macrophages regulates vesicular sorting and release of anti-inflammatory cargoes.

Hobbies and Extracurricular Activities

In addition to his scientific pursuits, Mike is an avid runner and competes in trail ultra-marathons as a member of the Some Work, All Play Adventure Team. Mike also runs for Bigger Than The Trail, a non-profit organization that raises money to support mental health counseling for those in need. When not in lab or outside running, Mike thoroughly enjoys reading, writing, and spending time with friends in the Graduate Program in Immunology.
