Journal Article
Suvannapruk, W., Fisher, L. E., Luckett, J. C., Edney, M. K., Kotowska, A. M., Kim, D., …Alexander, M. R. (in press). Spatially resolved molecular analysis of host response to medical device implantation using the 3D OrbiSIMS highlights a critical role for lipids. Advanced Science, https://doi.org/10.1101/2023.08.18.553860

A key goal for implanted medical devices is that they do not elicit a detrimental immune response. Macrophages play critical roles in modulation of the host immune response and are the major cells responsible for persistent inflammatory reactions to...
