© 2020 The Authors This study explores the hypothesis that simple polymer chemistries can be used to modulate the phenotype of human immune cells. Unbiased high-throughput screening of a large library of polymer chemistries is undertaken, identifying materials able to instruct macrophage attachment and polarization to pro- or anti-inflammatory phenotypes. The bioinstructive polymer function is validated by a murine model in which modulation of the foreign body response is shown. Polymer structure-cell response relationships modeled using machine learning reveal molecular descriptors useful for interpreting the immune-instructive polymers, highlighting the potential to undertake “immune-instructive” rational design. Identifying new polymers with immune-modulatory properties and elucidating the molecular mechanisms involved offer exciting possibilities to create novel bioinstructive materials with numerous clinical applications from implants and vaccine adjuvants to regenerative medicine and drug delivery.
