Lots of people could use neurostimulation equipment to treat their epilepsy. These units produce electrical stimulation towards the brain to lessen seizure frequency:
The mechanisms accustomed to evade the adaptive immune system tend to be more complex. The best approach will be to speedily modify non-essential epitopes (amino acids and/or sugars) about the area of the pathogen, even though keeping crucial epitopes hid. This is known as antigenic variation. An illustration is HIV, which mutates rapidly, Therefore the proteins on its viral envelope which have been important for entry into its host target cell are continually transforming. These Recurrent variations in antigens may well reveal the failures of vaccines directed at this virus.
