UCLA study uncovers clues for why Graves' disease attacks the eyes

... at Harbor-UCLA Medical Center. "The antibody provokes the receptor to signal the T-cell to grow and multiply ?long after the cell was programmed to die," he explained. "After two or three generations of this process, we suspect that the high-jacked T-cells mutiny over the normal T-cells, sparking the b...

Why aren't humans furry? Stone-Age moms could be the answer

Discovery of the first resistance gene to rice yellow mottle virus

...on or growing on low-lying land, where the disease provokes most damage. IRD geneticists have for several years been applying their research to the genetic bases of this resistance in order to facilitate its transfer to varieties that are agronomically useful yet susceptible to the virus with a view to optimi...

A new kind of mutation could explain numerous phenotypic variations in various species

...ation. The result is that the absence of myostatin provokes a muscular hypertrophy among Texel sheep. A mechanism observed in other species as well However, Michel Georges' team investigated further. Pursuing the study using bioinformatic approaches, the team identified polymorphisms (common mutations) amon...

Ebola virus: from wildlife to dogs

...mission to humans. Ebola virus infection in humans provokes a violent haemorrhagic fever. It usually flares up as intense epidemics. These kill 80 % of the people infected. Seven such outbreaks have hit Gabon and the Republic of Congo since 1994, leading to 445 cases resulting in 361 deaths. Ebola virus thus ...

Critical role in programmed cell death identified

...tation prevents cell death, inducing fragmentation provokes cell death. "This programmed cell death is so important and the more players we know that are involved, the more potential targets we have for therapeutics," Conradt said. During development, for example, many neurons are built, but after birth, mor...
