James R. Baker,
Research Interests: Autoimmune disease; Apoptosis; nanomaterials and biology; targeted therapeutic and enhanced contrast agents; pathogen defense and inactivation; adjuvant vaccine development
1. Dr. Baker's research in the area of autoimmune endocrine disease has helped define the basis of the autoimmune response to thyroid auto-antigens.
3. Dr. Baker heads the Michigan Nanotechnology Institute for Medicine and Biological Sciences ( M -NiMBS) a multidisciplinary team with scientists from the Schools of Medicine, Engineering and LS&A who work on the development of new platforms for drug delivery, most notably the development of a multi-function device for the diagnosis and treatment of cancer based on dendrimer technology. Dendrimers are tree branched polymers with a precise molecular structure, and of a size comparable to proteins. They are well tolerated by cells in vitro , and by mice in vivo .
4. M -NiMBS also develops functional MRI and SQUID imaging utilizing targeted magnetic nanoparticle contrast agents. The contrast enhancement is provided by superparamagnetic, metal containing nanoparticles based on dendritic polymers. Cellular targeting of the contrast agents is accomplished by conjugating the nanoparticles to folate molecules on the dendrimer scaffold, with binding and internalization of the contrast agents through the high-affinity folate receptor.
5. Using the dendrimer platform, M -NiMBS is developing a controlled release system of Morphine / Naloxone with a built in feedback system that controls the release of the antagonist, Naloxone, based upon the injured soldier's condition. Ideally this combination drug can be self-administered by the injured soldier on the battlefield.
