A specific variant of the surface protein VSG of African trypanosomes, the causative agents of sleeping sickness, is associated with resistance to the important drug Suramin. Scientists at the German Cancer Research Center have now been able to find a possible explanation for the formation of resistance based on the crystal structure of this protein variant.

An electronic nose for many applications

Sensory organs are sophisticated masterpieces of nature. That is why humans have often tried to copy them. Be it cameras or microphones - there are technical objects that have always been based on natural models such as the eye or the ear. For a long time, however, no artificial sense of smell has featured in the technical repertoire. Now researchers at the Karlsruhe Institute of Technology (KIT) have developed an electronic nose. It can…

The SARS-CoV spike protein and its receptor

The SARS-CoV-2 coronavirus uses a spike protein to bind to the ACE2 receptor on the cell surfaces of lung tissue. Additional cofactors are needed to allow the virus genome to penetrate human cells and multiply. Knowing these relationships can help understand the course of the infection and develop counterstrategies. To this end, the Constance-based company Trenzyme has produced a recombinant spike protein to support coronavirus research.

A rapid pyrogen test: the human immune system as model

Every year, around 11 million people die of sepsis (blood poisoning) caused by microorganisms or microbial residues, known as pyrogens, entering the bloodstream. The smallest amounts can trigger fever. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart have developed a pyrogen test that does not require a laboratory and is not tested on animals. It is expected to be placed on the market soon.

New pathogens in beef and cow's milk contributing to the risk of cancer

A team of researchers led by Nobel laureate Prof. Dr. med. Dr. h.c. mult. Harald zur Hausen has discovered a new type of infectious agent in dairy and meat products produced from European cattle that increases the risk for colon and breast cancer. These so-called Bovine Meat and Milk Factors (BMMFs) are small DNA molecules that are similar in sequence to both bacterial plasmids and certain viruses.

Advances in the study and treatment of liver diseases

Liver diseases are often underestimated despite being quite common and potentially having serious and even life-threatening consequences, especially in chronic cases. The most common causes of liver diseases are hepatitis viruses, excessive alcohol consumption, and obesity; congenital or autoimmune liver diseases are quite rare. Thanks to advances in medical research, diseases such as hepatitis B and C can be treated effectively.

New trends in the field of immunology

B- and T- lymphocytes along with macrophages have long been regarded as the most important cells of the human immune system and have been a major focus of research. This has now changed and it is now the dendritic cells that are regarded as the major components of the adaptive immune system. Research into innate immune defence mechanisms has become more important due to the discovery of the role of Toll-like receptors as first-line of defence.
