Molecular structure of one of the most important receptors in the immune system unraveled
Researchers publish the three-dimensional structure of the B cell antigen receptor, shedding new light on its composition
21-Oct-2022
The surface of B cells is covered with antigen receptors with which they recognize invading pathogens such as bacteria and viruses. When a B cell receptor binds to an antigen, that is, to a foreign structure, the B cell is activated and triggers the production of antibodies. Antibodies are ...
A molecular machine at work
Researchers unravel the assembly of an enzyme that detoxifies the greenhouse gas N₂O
05-Aug-2022
The greenhouse gas nitrous oxide (N2O) is produced as a by-product of industrial processes and through the use of fertilizers in agriculture. It is making a steadily growing contribution to climate change and the depletion of the ozone layer. It is so chemically unreactive that it remains in the ...
New discoveries about the origin of the brain’s immune system
Significance for Alzheimer’s, multiple sclerosis and more
03-May-2022
What gets into the brain and what doesn’t is strictly regulated. Researchers at the Faculty of Medicine at the University of Freiburg have now studied phagocytes that coat the blood vessels in the brain and reinforce the blood-brain barrier. As the scientists from the Institute of Neuropathology ...
Lung Tissue from the Lab
Organoids could be used in diagnosis, drug development, and fundamental research
22-Mar-2022
Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists from the University of Freiburg’s Faculty of Medicine have succeeded in collaboration with American researchers in generating tiny quantities of lung tissue, so-called ...
Complex pathways influence time delay in ionization of molecules
Study shows how the mechanism of photoionization can be used to gain insights into complex molecular potentials
18-Mar-2022
How can researchers use the mechanism of photoionization to gain insight into complex molecular potential? This question has now been answered by a team led by Prof. Dr. Giuseppe Sansone from the Institute of Physics at the University of Freiburg. The researchers from Freiburg, the Max Planck ...
3D tissue structures on the chip act as organs in miniature
New organ-on-chip system enables precise monitoring of 3D tumour tissue outside the body
23-Feb-2022
A research team around Dr. Andreas Weltin, Dr. Jochen Kieninger and Johannes Dornhof from the Department of Microsystems Engineering (IMTEK) at the University of Freiburg has developed a system that, among other things, makes it possible to study the development of tumour cells outside the human ...
Study analyzes technologies’ climate efficiency in removing carbon dioxide from the atmosphere
One process has similar CO2 footprint to e-mobility
02-Nov-2021
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated. A research team led by Kavya Madhu and ...
Crucial step identified in the conversion of biomass to methane
Researchers find the enzymatic link in the formation of methane from fatty acids by cooperating microorganisms
05-Oct-2021
Microbial production of methane from organic material is an essential process in the global carbon cycle and an important source of renewable energy. This natural process is based on a cooperative interaction between different types of microorganisms: the fermenting bacteria and the ...
Bacteria can boost the fitness of their host
01-Oct-2021
Microorganisms can increase their host’s ability to adapt to the environment and reproduce – evolutionary biologists are now studying the underlying molecular mechanisms. A research team headed by Dr. Fabian Staubach and Yun Wang from the Institute of Biology I at the University of Freiburg has ...
Novel strategy for natural product biosynthesis
Researchers discover enzyme prototype for formation of ecologically and pharmaceutically important tropone compounds
06-Jul-2021
Microorganisms produce natural products, for example, as disease-causing virulence factors or as defense substances against predators and competitors. A team led by Dr. Robin Teufel and first author Ying Duan from the Institute of Biology II at the Faculty of Biology of the University of ...
q&more – the networking platform for quality excellence in lab and process
