How to become a T follicular helper cell
Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear. Now, a team of researchers at the La Jolla Institute for Allergy and Immunology has identified a pair of master regulators that control the fate of TFH cells.

HVTN 505 vaccine induced antibodies nonspecific for HIV
A study by researchers at the National Institute of Allergy and Infectious Diseases and Duke University helps explain why the candidate vaccine used in the HVTN 505 clinical trial was not protective against HIV infection despite robustly inducing anti-HIV antibodies: the vaccine stimulated antibodies that recognized HIV as well as microbes commonly found in the intestinal tract, part of the body's microbiome. The researchers suggest that these antibodies arose because the vaccine boosted an existing antibody response to the intestinal microbiome, which may explain why the HVTN 505 vaccine candidate did not perform well. Understanding why the candidate vaccine did not protect against HIV infection will inform ongoing vaccine research efforts against HIV and other infectious diseases.

Newly identified molecular mechanism plays role in type 2 diabetes development
New research from Harvard T.H. Chan School of Public Health describes a molecular mechanism that helps explain how obesity-related inflammation can lead to type 2 diabetes. The findings describe a surprising connection between two molecular processes that are known to be involved in the development of metabolic disease‚ÄĒinflammation and endoplasmic reticulum (ER) dysfunction‚ÄĒand suggest that targeting this connection could aid in the development of new therapies.

Organic molecules on comets: Philae's first results from Churi prove surprising
Organic molecules never previously observed in comets, a relatively varied structure on the surface but a fairly homogeneous interior, organic compounds forming agglomerates rather than being dispersed in the ice: these are just some of first results provided by Philae on the surface of comet Churi. These in situ findings, which contain a wealth of completely new information, reveal several differences in comparison with previous observations of comets and current models.

An exceptional planetary system discovered in Cassiopeia
Astronomers have teased out a secret planetary system hiding in the arms of Cassiopea, just 21 light years away from us. The remarkable system, named HD219134, hosts one outer giant planet and three inner super-Earths, one of which transits in front of the star. The transiting super-Earth has a density similar to the Earth. It is by far the closest transiting planet known today. It provides the ideal candidate for follow-up studies and a deeper understanding of planetary formation, internal composition, and atmospheres. The system is so close that astronomers already dream about taking pictures of the new "Stars."

Comets: Soft shell, hard core?
Comet Churyumov-Gerasimenko poses new riddles: Surface material measurements performed by the Philae landing module indicate that the near surface material might have changed since its formation. Up to now, many researchers had assumed that it has remained in virtually the same state since its formation about 4.5 billion years ago.
