Researchers have discovered that a molecule best known for its anti-microbial properties also has the ability to activate key cells in the immune response. This newly discovered function, reported in the Nov. 1, 2002, issue of Science*, suggests the molecule, a peptide called ß-defensin 2, may be useful in the development of more effective cancer vaccines. Scientists have found that ß-defensin 2 initiates a chain of events leading to the growth and multiplication of T cells, components of the immune system that recognize and kill foreign cells that have invaded the body.
Defensins are known to be an important component of the bodys immediate response to infection. ß-defensin 2 attacks and destroys a broad range of bacteria as part of the innate immune system, the bodys first line of defense against such infections.
The new finding links ß-defensin 2 to the second arm of the immune system, adaptive immunity. The adaptive immune response combats pathogens that evade the bodys initial defense mechanisms. Unlike innate immunity, the adaptive immune system develops specifically in response to an infection, changing as needed to ward off each invader.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
