Discovery of the cell fate switch from neurons to astrocytes in the developing brain

IMAGE: In the process of fetal brain development, neural stem cells generate both neurons and astrocytes. Neurons are formed first (left) and astrocytes later (right). The present study has revealed the… view more  Background Neurons1 and astrocytes2 are prominent cell types in the cerebral cortex. Neurons are the primary information processing cells in the brain, whereas…

Immunology — not just supporting actors

Non-classical monocytes were long thought to play a purely surveillance role in the immune system. With the aid of a novel marker (PD-L1), Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have now shown that they are directly involved in the regulation of immune response. Monocytes comprise a functionally specific group of white blood cells and are known…
