Cross-section of the brainstem (IMAGE) Charité - Universitätsmedizin Berlin Caption Cross-section of the brainstem: Neurons (blue-gray) are in close contact with immune cells (purple). The threadlike blue structures are extensions of the neurons, which can reach all the way into distant organs in the form of nerve fibers. According to the study, the immune cells and neurons in the brainstem can be activated directly via the nerve fibers as a result of inflammation in the lungs. © Charité | Jenny Meinhardt Credit © Charité | Jenny Meinhardt Usage Restrictions Publication only with reference to the press release or paper License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
