Our immune system works around the clock to protect us from bacteria, viruses, and other harmful germs. It also helps repair damaged tissues after injuries. One of its most important defense tools is ...
The brain has its own immune system, which detects threats and mounts a defense. A growing body of evidence has shown that in Alzheimer's disease, those immune cells are chronically overactivated, ...
Alveolar macrophages are immune cells that live in the tiny air sacs of the lungs. Under normal conditions, these cells act as guardians, keeping the lungs healthy, supporting breathing, and ...
Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...
Lipopolysaccharide (LPS) can trigger an inflammatory response in lung epithelial cells, which may contribute to the development of Acute Respiratory Distress Syndrome (ARDS). Epigallocatechin-3- ...
Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short. Among other things, they regulate inflammatory reactions and influence ...
Scientists have gained major new insights into inflammatory bowel disease, a term that includes the gastrointestinal ...
Belgian scientists have uncovered new details about how the immune system responds to vaccines. Dendritic cells, which are key immune messengers that help kick-start the body's defenses, show specific ...
Mast cells are part of our immune system, protecting our body from viruses, bacteria, and even harmful substances released by snake and insect bites. When alerted to the presence of such invaders, ...
Glioblastoma (GBM) is a highly heterogeneous, aggressively invasive, and very malignant tumor located in the central nervous system. Although treatments, such as radiotherapy (RT), chemotherapy, and ...
Connections between nerve cells in the brain (synapses, labeled green) usually deteriorate in the brains of Alzheimer's mouse models (left). Stopping the formation of a molecule known as SNO-STING ...
