Duke Researchers Discover Candidate Susceptibility Gene For Autoimmune Disease
..., Blackshear's teamdetermined that the animals had characteristic antibodies against theirown tissues that represent an inflammatory autoimmune response. By comparingtheir mice with other animals that had similar clinical signs, the researchershypothesized the animals were producing too much of a potent inflammator...NADC Examines TB In Cattle and Swine

As the proteins begin twisting intotheir characteristic shapes, a series of pulses from an ultraviolet lasercause some of the amino acids to fluoresce, revealing to the researchersa time-sequence of folding events.
