How does the brain adapt our behavior in response to an infection or injury? A multidisciplinary team of scientists from the Institut Pasteur, CNRS and Inserm have revealed the existence of a circuit involved in sensing and also in the regulation of the anti-inflammatory response orchestrated by different brain regions. This circuit detects inflammation in the blood and organizes and regulates the immune response. It embodies a two-way connection between the brain and immune system. The results were published on June 5, 2023 in the journal Neuron.
Whenever infections or injuries occur, the immune system is triggered to control the infection and repair damaged tissue. This process involves the release of pro-inflammatory mediators that inform the brain of the body’s immune status and coordinate the immune response. In response to this signal, the brain triggers a complex reaction…
