New medical implants should react with the body, not seek to be inert
...e chosen because they are reasonably successful at hiding from the bodys immune system, and are consequently not rejected. All the same, within a month of implanting them, the body isolates implants by wrapping them in a collagenous, avascular sac.

...brown result. The brown tip might result from dirt hiding a red chemical reaction. Another explanation is that household dirt could interfere with the reaction between the dye in the swabs and reactive lead in the dust, researchers noted. Yet even when results were interpreted conservatively that is, eve...'Insulator' helps silence genes in dormant herpes virus
... infection, the virus usually remains in the body, hiding out in nearby nerve cells where the victim's immune defenses cannot reach it, causing no symptoms at all. In order to escape detection by the body's immune system, the latent virus works to silence genes that would cause it to replicate.
