Immune Cell Communication, Cooperation Keys to Hunting Viruses

Abstract:
Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel “biosensor” to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses.

They found that surprisingly little virus can turn on the killer T-cells, thanks to some complicated communication among so-called “antigen presenting” proteins that recognize and attach to the virus, in turn, making it visible to the immune system. T-cell receptors then “see” the virus, activating the T-cells.
