A stem cell-derived in vitro model displays key small intestine characteristics including innate immune responses, according to a new study.
In vitro 3-D cell systems, so-called "organ-on-a-chip," are the focus of intense study, with the hope that they may one day replace animal models in bridging the gap between conventional cell cultures and clinical trials.

The U.S. Food and Drug Administration is aiming to approve drugs based on very early data if the drug shows a possible benefit in terms of survival, the head of the agency told lawmakers. Speaking before the House Committee on Energy and Commerce, Food and Drug Administration Commissioner Scott Gottlieb said the agency would approve such drugs quickly and figure out later whether the benefit seen was real or coincidental.

In a New England Journal of Medicine perspective, experts from the National Institute of Allergy and Infectious Diseases part of the National Institutes of Health, and the World Health Organization Collaborating Centre for Reference and Research on Influenza discuss how the process of preparing seasonal influenza vaccines in eggs may contribute to their limited effectiveness. The authors offer research strategies that might yield more protective vaccine candidates.

A new vaccine technique can fight a certain type of breast cancer in mice. So-called HER2-positive breast cancer accounts for between 20 and 30 percent of all cases of breast cancer in humans. Researchers from the University of Copenhagen and the University of Bologna now show that the same type of cancer can be fought in mice with help of their new vaccine.

Monitoring disease activity in individuals with multiple sclerosis, either to predict flare-ups or to check treatment response, might be done with a simple blood test that measures levels of a nerve protein, according to a new study from Norway.
The findings, which have now been published in the journal Neurology: Neuroimmunology & Neuroinflammation, are the work of Dr. Kristin N. Varhaug, of the University of Bergen in Norway, and her colleagues.

A team of scientists has developed drug-carrying nanoparticles that can find and kill cancer stem cells, a tiny group of rare cells that can hide in tissue and cause cancer to return years after tumors have been treated.
In a paper published in the journal Molecular Cancer Therapeutics, researchers at the University of Illinois at Urbana-Champaign explain how they developed nanoparticles that can seek and latch on to a protein called CD44, which is found only on the surface of cancer stem cells.
