University of California, Santa Barbara Researchers Discover Shape Matters To Macrophages

Researchers at UC Santa Barbara have made a surprising discovery: phagocytosis depends more on particle shape than size. The research, which has far-reaching implications for immunology, vaccine development and drug delivery, is published today online in the Proceedings of the National Academy of Sciences by Samir Mitragotri, a UCSB professor of chemical engineering, and graduate student Julie A. Champion. The paper will be published in print on March 28.
