One of these involves the T-cells of the immune system, which have a number of different proteins on their surface called &#8216;checkpoint proteins.&#8217; These checkpoint proteins bind to proteins on the surface of other cells and can result in either stimulation or suppression of T-cell activity. Normally, surface proteins on foreign or invading cells will produce a stimulation of T-cell activity against these cells, while T-cell suppression is a built-in mechanism to prevent the immune system from attacking the body&#8217;s own normal cells.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-02-breast-cancer-on-a-chip-immunotherapy-drugs.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Breast cancer-on-a-chip for testing immunotherapy drugs<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are many mechanisms by which the body responds to foreign invaders.
