The Meng lab focuses on design and characterization of inspired drug delivery systems for modulating immune functions. The group pursues projects that bridge gaps between preclinical and clinical stages in drug development in enhancing drug bioavailability in diseased tissues while limiting systemic toxicities. The strategic themes are to optimize experimental and approved biologics for locoregional treatments of graft rejection, type I diabetes, and solid tumors. Current research themes include 1) Develop bioaffinity hydrogels formed by self-assembling peptides in delivering immunoregulatory antibodies and Fc fusion proteins, 2) Optimize surface-functionalized microparticles for formulating recombinant proteins, nucleic acids, and poorly water-soluble small molecules as therapeutics, 3) Apply MHC bioinformatics and T cell epitope cross-reactivity mapping in predicting immunogenicity of recombinant protein therapeutics, and 4) Engineer artificial thymic organoids to reprogram T cells.

The Meng group has developed particles that combine the polymer PLGA and the polycation O10H6 as nucleic acid delivery systems (Chamarthy et al, 2003, 2004; Kovacs et al, 2005; Zheng et al, 2006; Jia et al, 2006, 2008; Kovacs et al 2009). The group is testing PLGA-O10H6 particles to deliver the interleukin-10 gene in a mouse transplant model (funded by NIH). In collaboration with Nick Giannoukakis and Yong Fan (Allegheny-Singer Research Institute), the group is developing nanostructures for delivering immune programming factors to delay the onset of type-I diabetes in mice (funded by JDRF and NIH). Working with Lisa Weiland (Pitt) and Eric Freeman (Univ. of Georgia), the group constructed a mathematical model predictive of amine-induced endosomal burst (Freeman et al, 2010, 2012). Together with Mat Saunders and Alan Waggoner at Carnegie Mellon, the group is developing injectable biosensors for drug delivery applications (Saunders et al, 2013 and Liu et al., 2016). The group has a strong interest in MHC bioinfomatics/T cell epitope prediction (Joseph et al, 2007; Andrick et al, 2014 in preparation). More recently, the group has characterized injectable peptidic membranes (functionalized EAK16-II) to extend the accumulation of antibodies locally in vivo (Zheng et al, 2011; Wen et al, 2013, 2014a, 2014b; funded by PA-CURE and NIH R21).
