Indeed, the axon-carrying dendrite is privileged in exciting the axon, creating a fundamental asymmetry in dendritic integration. The work may, therefore, have important consequences for understanding signaling and information processing in the hippocampal network. A tribute to Peter H. Seeburg 8. Seeburg, a world leader in research on memory and learning, died in Heidelberg on 22 August at the age of Peter managed to cross several frontiers in biology and opened many new avenues of research.
Peter revolutionized fast DNA sequencing, one of the essential prerequisites for the human genome project. He isolated and characterized some of the most important peptide hormones, receptors and ligand-gated ion channels, and he provided the first genetic evidence defining which of these key mediators of cellular communication are critically involved in learning and memory. Calcium signal in cell nucleus regulates not only many brain functions but also defence reactions of the immune system Cells of the immune system can distinguish between protein molecules that are "self" and "non-self".
In contrast, cells are "tolerant" of the body's own molecules. This state of unresponsiveness, or anergy, is regulated by a cellular signal, a calcium-controlled switch that was known to control also many brain functions. Neuroscientists from Heidelberg University and immunologists of Heidelberg University Hospital identified this signal.
The research work was led by Prof. The Heidelberg research team identified a calcium signal in the cell nucleus of human T lymphocytes as a decision-maker in the immune system. They showed that a nuclear calcium signal is required for the immune reaction that T-cells trigger after contact with molecules foreign to the body.
Herta Flor honored with John D. The John D. Loeser Distinguished Lecture Award recognizes Dr. John D. Loeser for his decades of dedication to the promotion of pain education and research. The award is intended to create a tradition that instructs, inspires and challenges clinicians and researchers to understand human pain and the suffering it produces in the broadest ways possible.

His work on the relationship between brain stem cells and brain tumour stem cells has yielded important results.
He identified the Tlx protein as the key molecule in brain tumour stem cells. When the Tlx molecule was genetically switched off in mice, the tumour stem cells were unable to regenerate and the diseased animals survived longer. Tlx therefore holds much promise for new treatment strategies for glioblastoma, the most aggressive type of brain tumour.
Liu and his associates also succeeded in tracking the genetic lineage of brain tumour stem cells in the living organism. Research findings of Heidelberg neurobiologists could lead to new treatment approaches for memory loss and anxiety disorders Increasing the level of a certain DNA-modified enzyme in the brain significantly improves cognitive ability. The discovery was made by the research team led by Prof. Mouse experiments showed that the Dnmt3a2 protein can boost memory performance in the animals.
Because this protein also affects fear memory and the ability to erase bad memories, the researchers hope these findings can be used to develop new treatments for post-traumatic stress disorder and other forms of anxiety. The results of the research were published in the journal Molecular Psychiatry. In an earlier study, the Heidelberg scientists learned that there are reduced levels of Dnmt3a2 protein in the brains of older mice. When the elderly animals were injected with viruses that produce this protein, their memory capacity improved.
In a number of different long-term memory tests, including classic Pavlovian conditioning, the scientists were able to demonstrate that mice with more Dnmt3a2 on board performed considerably better. Klaus H. Welche Rolle spielt Kalzium bei Multipler Sklerose?

It particularly affects regions of the brain that are fundamental for memory and learning. The junctions through which the nerve cells communicate, the synapses, disappear long before the nerve cells die, damage that impairs both learning and memory.
