Ultrafine Particles Aggravate Asthma

How do pathogenic agents actually manage to overcome the defence barriers of the human body and attack the organism? The team around Professor Dr. Dirk Heinz at the Department of Structural Biology of the HZI pursues this question.

Salmonellae are bacterial pathogenic agents that rapidly proliferate in insufficiently cooked egg dishes in warm weather causing commonly known and infamous consequences. Less known, but no less interesting, is the fact that in addition to ice-cream and egg dishes salmonellae also interact with tumour tissue.

The genome is the genetic material stored within the nucleus of every cell, consisting of a sequence of 3.2 billion DNA building blocks. In 2003, an international research team delivered the completely decoded human genome and thus completed the work on the human genome project begun in 1990. Now, German researchers have joined a new mammoth project of biomedical genome research.

Blood cells live only a limited time. Therefore, the body perpetually creates new blood cells. Their reservoir is constituted by the blood stem cells. Depending on a chemical process long known to researchers, a blood stem cell either turns out to be a stem cell again after cell division or various blood cells develop.

The risk for diabetes or other metabolic diseases increases enormously, when unhealthy eating habits and a lack of exercise coincide with genetic disposition. Researchers of Helmholtz Zentrum München discovered variants of known diabetes risk genes and other genes, which for the first time they could definitely link with lipometabolism disorders.

Usually, metabolic regulation ensures energy balance so that the body weight remains fairly stable. In the event of increasing obesity, more energy is deposited in the so-called white adipose tissue than is used. By contrast, brown adipose tissue has a different function, converting energy into heat. The idea is, therefore, that brown adipose tissue could possibly help to restore the disturbed balance between absorption and consumption of energy.

Some 250,000 people per year in Germany sustain a stroke. The majority of people affected then suffer from consequential damages such as paralysis and language or vision disorders. In collaboration with French colleagues, researchers
led by Professor Dr. Norbert Hübner of the MDC have now developed a mouse model enabling the detailed study of risk factors for stroke development.

As life expectancy increases more individuals retain good health lfor a longer time. However, also the risk of cancer, cardiovascular and neurodegenerative diseases increases with age. Today, neurodegenerative diseases take a significant toll as cause of death in old age. In Germany around one million individuals are affected by dementia.
