The Role of Oligodendrocytes in MS
News Nov 13, 2018Mapping of a certain group of cells, known as oligodendrocytes, in the central nervous system of a mouse model of multiple sclerosis (MS), shows that they might have a significant role in the development of the disease. The discovery can lead to new therapies targeted at other areas than just the immune system.
Obesity and Cancer: ‘Fat-clogged’ Immune Cells Fail to Fight Tumors
News Nov 12, 2018Researchers have gained a new understanding of the link between obesity and cancer. In the presence of excess fat, the immune surveillance system fails due to an obesity-fueled lipid accumulation in natural killer (NK) cells, preventing their cellular metabolism and trafficking.
