A member asked:

If the immune system targeted specific nerves cells why would the body not be able to feel the process of those nerves cells being attacked?

A doctor has provided 1 answer

No sensory nerves...: If there are no sensory nerve endings in that part of the body, then no sensations are detected, so thus the brain receives no information (and so we don't "feel" anything going on). Imagine a city with 1000 security cameras. There will be "blind spots" in places that the cameras aren't looking. The police do not see things that are happening in the "blind spots".
