Immune system abnormalities that mimic those seen with autism spectrum disorders have been linked to the amyloid precursor protein (APP), reports a research team from the University of South Florida's Department of Psychiatry and the Silver Child Development Center. The study, conducted with mouse models of autism, suggests that elevated levels of an APP fragment circulating in the blood could explain the aberrations in immune cell populations and function -- both observed in some autism patients. The findings were recently published online in the Journal of the Federation of American Societies for Experimental Biology. The USF researchers concluded that the protein fragment might be both a biomarker for autism and a new research target for understanding the physiology of the disorder. "Autism affects one in 110 children in the United States today," said research team leader Jun Tan, MD, PhD, professor of psychiatry and the Robert A. Silver Chair, Rashid Laboratory for Developmental Neurobiology at USF's Silver Child Development Center. "While there are reports of abnormal T-cell numbers and function in some persons affected with autism, no specific cause has been identified. The disorder is diagnosed by behavioral observation and to date no associated biomarkers have been identified." "Not only are there no associated biomarkers, but the prognosis for autism is poor and the costs associated with care are climbing," said Francisco Fernandez, MD, department chair and head of the Silver Center. "The work of Dr. Tan and his team is a start that may lead to earlier diagnosis and more effective treatments." The amyloid precursor protein is typically the focus of research related to Alzheimer's disease. However, recent scientific reports have identified elevated levels of the particular protein fragment, called, sAPP-?, in the blood of autistic children. The fragment is a well-known growth factor for nerves, and studies imply that it plays a role in T-cell immune responses as well. To study the autism-related effects of this protein fragment on postnatal neurodevelopment and behavior, Dr. Tan and his team inserted the human DNA sequence coding for the sAPP-? fragment into the genome of a mouse model for autism. While the studies are ongoing, the researchers documented the protein fragment's effects on the immune system of the test mice. "We used molecular biology and immunohistochemistry techniques to characterize T-cell development in the thymus and also function in the spleen of the test animals," Dr. Tan said. "Then we compared transgenic mice to their wild-type littermates." The researchers found that increased levels of sAPP-? in the transgenic mice led to increased cytotoxic T-cell numbers. The investigators also discovered subsequent impairment in the recall function of memory T-cells in the test mice, suggesting that the adaptive immune response is negatively affected in the presence of high levels of the protein fragment. "Our work suggests that the negative effects of elevated sAPP-? on the adaptive immune system is a novel mechanism underlying certain forms of autism," concluded Dr. Tan, who holds the Silver Chair in Developmental Neurobiology. "The findings also add support to the role of sAPP-? in the T-cell response." Other researchers involved in this study were Antoinette Bailey, Dr. Huayan Hou, Dr. Demian Obregon, Jun Tian, Dr. Yuyan Zhu, Dr. Qiang Zou, Dr. William Nikolic, Dr. Michael Bengston, Dr. Takashi Mori (Saitama Medical Center/Saitama Medical University, Japan) and Dr. Tanya Murphy. The work was supported by the Silver Endowment and a grant from the National Institutes of Health/National Institute of Mental Health.

In the boxer's case, those blows are delivered over the course of a few decades. In the case of the Moon, the punishment has been going on for billions of years, courtesy of comets and asteroids that carved out craters and piled up mountains all over the lunar surface. The very birth of the moon was violent: planetary scientists are pretty sure our companion world was created when a Mars-size object slammed into Earth and ripped off a Moon-size chunk. Much of our understanding of that violent history comes from rocks hauled back by the Apollo missions four decades ago. But the astronauts who gathered that evidence literally just scratched just the surface -- and many of the Moon's secrets are buried far deeper. PHOTOS: Hubble's Greatest Hits That's why the GRAIL mission, which successfully inserted itself into lunar orbit over the weekend, is so crucial. GRAIL, the Gravity Recovery And Interior Laboratory, will be probing deep beneath the Moon's surface to analyze its interior structure in unprecedented detail. Since that structure reflects how the Moon was originally formed and the violence done to it since, GRAIL will fill in all sorts of blanks about our satellite's birth and evolution. That's the "what," but it's the "how" that's so ingenious and that deserves a bit of explanation. GRAIL is not one, but two identical satellites that will orbit in tandem, 35 miles above the surface -- GRAIL A in front, GRAIL B following tens of miles behind. If the Moon were simply a featureless, homogenous sphere of rock, the distance between A and B wouldn't change. The Moon isn't featureless, though: in some places there's extra stuff piled on the surface (mountains, crater walls) and in others there are gaping pits -- the craters themselves. When GRAIL A approaches a mountain, the peak's extra gravity pulls on the probe, making it speed up just a bit, while GRAIL B, still out of range, doesn't yet feel the tug. The distance between the two spacecraft increases, and the probes' electronics record the increase, even when the gap widens by no more than the width of a red blood cell. When GRAIL A approaches a crater, by contrast, there's a little less gravity than usual to pull it along. A slows a little, B catches up slightly, and that change is recorded as well. GRAIL B will trail GRAIL A from pole to pole, the pair completing one orbit every two hours as the Moon rotates slowly underneath. Over the mission's three-month lifespan, the twin ships will make three complete gravity maps of the entire lunar globe. But surface features aren't all the probes will study. There are also regions of higher and lower density buried beneath the lunar surface. These mass concentrations -- or mascons -- are the likely result of ancient volcanism or ancient impacts. They too exert differing gravitational pull, with the denser material pulling harder than the less dense, and those differences will be detected by the GRAILs as well. So sensitive are the spacecraft that they will effectively be able to see -- gravitationally speaking -- all the way down to the lunar core. All of these readings will be analyzed along with one other data stream: the slight flexing the entire moon undergoes as a result of the tidal pull of the Earth. The nature of the flexing will be partly determined by what the Moon's deep structure looks like -- whether the core is solid or semi-solid or molten, for example. Best of all, there isn't the slightest doubt that this twin-satellite concept can work: it's based on the wildly successful GRACE (Gravity Recovery And Climate Experiment) mission, which has been orbiting Earth since 2002. By noting changes in our planet's gravity, GRACE has, among other things, discovered a giant impact crater underneath the Antarctic ice sheet, measured ice loss in Greenland and Antarctica and noted depletion of groundwater during the recent U.S. drought. If GRAIL does half as well as GRACE -- and there's every reason to think it will -- the textbooks on selenology, or lunar geology, may have to undergo some major revisions. Finally, it's worth noting yet another thing that makes the GRAIL mission so extraordinarily clever. Rather than take a direct route across the 250,000-mile Earth-Moon gap -- a journey that took the Apollo astronauts just three days -- GRAIL meandered through space on a loop-the-loop path known as a "weak boundary trajectory" that lasted more than three months, following the path of least resistance through the complex terrain created by the interacting gravitational fields of Earth, Moon and Sun. Going slow meant not only that the spacecraft needed less fuel, but also that engineers had longer to check out the probes' electronic health. Plus when GRAIL finally arrived, it took less energy to ease it into a lunar orbit . Back in 1990, just such a "weak stability boundary" trajectory was first used to salvage the Japanese Hiten satellite, which failed in its original attempt to reach the Moon and didn't have enough fuel for a second try. In a brilliant bit of cosmic inventiveness, a mathematician-turned-rocket-scientist-turned artist named Ed Belbruno calculated a new slow, low-energy route for Hiten and saved the mission. Fortunately, lunar experts, including MIT's Maria Zuber, GRAIL's lead scientist, won't have long to wait for the results of the mission. GRAIL should be all wrapped up by early summer, and by the time the one-year launch anniversary rolls around in September, we should know a lot more about the long and violent history of our nearest, but still largely unknown, cosmic neighbor.

Instead of reviewing my activities in the past year, I thought I?d do something a little different and share with you the blog posts and news articles from 2011 that I found the most memorable. Because there are so many, this post contains links from January through June. If I remember to do a part two, that list will undoubtedly be shorter because I started my current job in June and have had much less time for blog and news reading. Browse, read, and enjoy. Glancing over this list, I think it probably tells you a thing or two about where my greatest interests lie.
