Duke Researchers Discover Candidate Susceptibility Gene For Autoimmune Disease
...earchers injected the TTP-deficient animalswith an antibody
that neutralizes TNFa. In a dramatic and almost completereversal, all signs of disease completely disappeared. The findings support preliminary results of human clinical trials beingconducted at Duke and other research institutions of an experiment...
Huntington's Disease Findings Pave Way For Potential Cure
...nuclear inclusions(NII). Analysis using monoclonal antibody
technology not available in 1979revealed that NIIs were aggregates (clumps) of huntingtin protein. The proteinentered the cell nucleus through pores in the nuclear membrane. The NII werepresent in the brain cell nuclei of mice with symptoms very s...
Evolution Re-Sculpted Animal Limbs By Genetic Switches Once Thought Too Drastic For Survival
...ds of crustaceans we eat." The researchers used an antibody
that labels the proteins made by two closelylinked homeotic genes, Ubx and abdA, to show in which segments of the embryo thegenes are turned on. The Ubx-abdA genes--like other homeotic genes, includingthe one that can cause a fruit fly to grow a leg ...
Virologists Track New Influenza Threat
