The Biomembrane Lab / Mayer Group

Research in the Biomembrane Lab focuses on transport and signaling processes across biological membranes. The goal of the group is to increase the molecular understanding of these processes and ultimately to employ the ensuing insight to diagnose and possibly treat human disease. We are particularly interested in ion channel proteins that are involved in Alzheimer’s disease and in autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and type I diabetes mellitus, as well as in transporter proteins that are responsible for resistance to chemotherapy in treatment of cancer.

Current research focuses on five main projects:

  1. High-throughput profiling of ion channel activity in human lymphocytes as a biomarker for T cell-mediated autoimmune diseases
  2. Chip-based transport assays of single multidrug resistance transporters
  3. Screening for small molecules that inhibit neurotoxic ion channel activity by amyloid-beta (AB) peptides as a possible strategy to treat Alzheimer’s disease (AD)
  4. Nanopore-based sensing of biomolecular assemblies and artificial ion channels
  5. Interactions of proteins and therapeutic drugs with biomembranes and lipid rafts

Research in the Biomembrane Lab is carried out in a multidisciplinary approach; we combine expertise in biochemistry, cell biology, and immunology with state-of-the art approaches in biophysics, electrophysiology, optical single molecule detection, and surface chemistry. The lab works in teams; current members include two postdoctoral researchers, four graduate students, and three undergraduate students.
