Various receptors in and on the cells recognize certain molecules, pack them and ensure that they are transported to the right place. One of these receptors is Sortilin. It is present in the cells of the nervous system, the liver, and the immune system.
Interferon-gamma is produced by cytotoxic T cells (formerly: T killer cells), T helper cells and natural killer cells. It enhances the activity of immune cells and induces other cells of the body to increasingly present fragments of the pathogen on their surface so that the T cells can find the affected cells more easily. To facilitate the transport of interferon-gamma from the interior of the T cell where it is produced to the cell membrane where it can be released, the cell uses its interior processing and transport system, to which the Golgi apparatus belongs.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...
An important step towards a completely new experimental access to quantum physics has been made at University of Konstanz. The team of scientists headed by...
Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
