autoimmune disease
A hint to the root of autoimmune disease in women?
Researchers are homing in on an explanation for why women are more likely to develop autoimmune disorders than men. In mice, Stanford scientists found that an RNA molecule called Xist helps prevent female cells from activating both sets of their X chromosome genes, which would be deadly. These molecules can trigger antibodies to latch onto RNA and its protein counterparts. Male cells don't typically express Xist.
When the researchers looked at blood samples from healthy adults and patients with autoimmune diseases typically seen in women, they found that the latter group was more likely to have antibodies that recognized Xist-protein complexes. This offers potential for new ways to monitor or treat autoimmune disease.
"This is like a completely different and novel explanation for female bias in immune disease," the study's senior author told STAT. "What our study really showed was that it's not just the second X chromosome, it's actually a very special RNA that comes from that second X chromosome, and just that RNA perhaps plays a major role."

Studying Arena BioWorks' model
With deep pockets and an even deeper talent pool, Arena BioWorks offers a compelling new approach to biological innovation. But it remains to be seen whether throwing a ton of money at a select few accomplished scientists is an effective and efficient way to produce fast scientific results, opines Paula Stephan, a researcher at the National Bureau of Economic Research. Since it will be funding high-risk, high-reward research outside of the university setting, it'll be important to study it closely.
"I strongly encourage Arena to invite social scientists to study their model with the goal of seeing the extent to which it fosters innovation and if so, what parts of the model might be transferable to other research settings, including the university," she writes.
