Jennifer K. Nyborg, In recent years, human T-cell leukemia virus type 1 (HTLV-1) has become increasingly recognized as an important cause for public health concern throughout the world and is the causative agent of a variety of clinical diseases, including an aggressive and fatal cancer called adult T-cell leukemia, and a neurological disorder that is clinically very similar to multiple sclerosis. A large body of evidence suggests that the clinical manifestations of HTLV-1 infection occur as a consequence of a virally-encoded protein called Tax. My laboratory focuses on defining the intracellular consequences of Tax expression in the infected human cell, with emphasis on the Tax-dependent events that lead to malignant transformation.
Olve Peersen, Picornaviruses are a family of small positive sense single stranded RNA viruses that cause a wide range of diseases in humans and animals including rhinoviruses that cause the common cold and poliovirus, the prototypical member of this family.

Daniel R. Bush, My research focuses on sugar and amino acid allocation from sites of primary assimilation to import-dependent sinks in plants. This is a fundamental process that allows plants to function as multicellular organisms. We use molecular, genetic and biochemical tools to define the mechanisms and regulation of this essential process.
