Moreover, our findings indicate that the effects of non-masked and masked LPS on human immune cells (monocytes in this study) are very similar, which demonstrates that endotoxin triggers immune responses whether it is masked or not.
Now a group at Tulane University, led by Darwin Prockop, director of the Center for Gene Therapy, has found that injecting human stem cells into the brains of stroke-induced mice triggers immune cells to produce chemicals that protect nerve cells, thereby reducing swelling and scarring.
The chemically modified MBP then triggers immune responses throughout the brain.
Allergens stimulate production of a special type of antibody called immunoglobulin E (IgE), which triggers immune cells to release substances such as histamine that cause wheezing and other symptoms.
"Sleep deprivation triggers immune suppression".
Although infection of Arabidopsis triggers immune responses similar to those known from other plant pathogens, S. typhimurium is able to overcome the host defence mechanisms and multiply in Arabidopsis plants.
