| |  The immune system is composed of a wide range of different immune cells each with dedicated functions. Natural killer T cells form a specialized immune cell that protects against a variety of diseases such as cancer, autoimmunity, metabolic disease or certain infections such as Lyme disease. | |
|
| |  Researchers have manipulated T cells in a way that prevents the rejection of transplanted organs, without affecting the immune system’s ability to fight microbial infection. | |
|
| |  Doctors would prefer to use all kinds of nanoparticles in the body, for instance, to create comprehensive images of anatomy and disease, and to deliver cancer-fighting drugs deep inside the tumor tissue. | |
|
| |  In a study of fruit flies, NIH scientists suggested that the body's immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development and may be involved in neurodegenerative diseases, such as ALS, Alzheimer's and Parkinson's disease. | |
|
| |  Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to travel via blood vessels to reach the site of infection. Their work appears on January 15 in the journal Immunity. | |
