 Nature: 1918 Flu - 90 years of immunity
Antibodies isolated from survivors of the 1918 pandemic influenza virus can protect mice from lethal infection, according to research published online in Nature this week. The finding proves that the immune system in these individuals still 'remembers' the virus nearly 90 years after the initial infection.
James Crowe and colleagues found that all 32 individuals tested, born in or before 1915, had antibodies that recognised the 1918 strain of the flu virus. Several of the individuals also had circulating B cells that were still produced these specific antibodies. Importantly, the antibodies were still functional and were able to protect mice from experimental infection with the 1918 viral strain.
The team went on to identify the area on the virus where the antibodies bound to stop infection. The authors suggest that these antibodies could act as useful therapeutics, should another virus similar to the 1918 flu strain ever emerge.

 &  Genetics: New susceptibility gene for type 2 diabetes
Scientists have identified variants that increase risk of type 2 diabetes in populations of both East Asian and European origin. Each copy of one of these risk variants increases an individual’s odds of getting the disease by 30–40%, an effect that exceeds all of the other susceptibility genes identified to date, with the exception of TCF7L2.
Online in Nature Genetics this week two groups report genome-wide association studies of Japanese individuals with type 2 diabetes. Masato Kasuga and colleagues found variants in KCNQ1 to be associated with increased risk of the disease, which they subsequently replicated in populations from Korea, China and Sweden. Shiro Maeda also identified risk variants in KCNQ1 in Japanese, and replicated the associations in affected individuals from Singapore and Denmark. KCNQ1 encodes a potassium channel subunit, and although KCNQ1 mutations have most prominently been associated with life-threatening cardiac arrhythmias, the gene has also been reported to regulate insulin secretion in the pancreas.
The risk variants have a similar effect in both East Asian and European populations, but they are much less frequent in Europeans, which may explain why they were not previously identified in the European-based large-scale studies of type 2 diabetes. As such, these results add to the growing body of evidence that the frequency of disease susceptibility variants may differ depending on ancestry, and underscore the importance of carrying out genome-wide association studies of individuals of non-European descent.

 Genetics: Ion channels implicated in bipolar disorder
Variants in two genes are associated with increased risk of bipolar disorder, according to a study published online this week in Nature Genetics. Bipolar disorder is a common mood disorder formerly known as manic depression, and is characterized by alternating episodes of mania and depression.
Previously published genome-wide association studies have generated suggestive evidence for genetic risk factors, although with little agreement from study to study. Pamela Sklar, Nick Craddock and Shaun Purcell led a collaborative effort to re-analyze the published results in combination with a genome scan of an additional group of individuals with the disease.
The strongest evidence for genetic risk factors was for variants in ANK3 and CACNA1C. The gene ANK3 encodes a protein called ankyrin G, which has been reported to regulate the assembly of sodium channels. The gene CACNA1C, encoding a calcium channel subunit, provides support for an association that had previously been suggested. Some of the authors had also previously shown that both these genes are down-regulated in the mouse brain in response to lithium, which is one of the most effective therapies for bipolar disorder. The data raise the possibility that bipolar disorder is, in part, a result of altered ion channel function.

 Nature: Cancer taking the Myc
Therapies that block the action of a gene called Myc may prove useful against cancer, suggest results from a mouse study in this week’s Nature.
Myc is a regulatory gene found in normal, healthy cells. However, it is commonly overexpressed in tumours, making it a possible target for anti-cancer therapies. Gerard Evan and colleagues now show that when Myc is inhibited in a mouse model of lung cancer, early and established tumours quickly regress. Importantly, in this model Myc was not overexpressed, demonstrating that Myc might be a more general therapy target.
Critics warn that cancer therapies that block Myc could cause devastating side effects because the gene helps regenerative tissues, such as those found in skin and bone marrow, to replenish themselves. Although the mice in this study showed no overt signs of ill health or distress, bone marrow proliferation and white blood cell count were reduced, and the animals also became anaemic. However, the side effects were short lived and disappeared after two weeks, suggesting that Myc may be a viable anti-cancer target after all.
