A research group led by Prof Wang Ruibing in the Institute of Chinese Medical Sciences (ICMS), University of Macau (UM), and another research group led by Prof Zhong Zhiyuan at Soochow University, proposed the concept of ‘supramolecular cell’ (cells with synthetic receptors anchored on the surface). According to the study, the supramolecular ‘cell-hitchhiking’ drug delivery system can significantly improve targeted delivery efficiency in treating inflammatory diseases and achieve desirable therapeutic efficacy for acute lung inflammation in mice.
