How Do Natural Killer Cells Destroy Invading Pathogens
There is an increasing understanding that Natural Killer NK cells not only exhibit direct activity against bacteria but also exert indirect antibacterial activity through interaction with other immune cells via cytokines and interferons. Unlike T cells however NK cells do not express antigen-specific receptors. 23 1 Innate Immune Response Concepts Of Biology 1st Canadian Edition After a pathogen enters the body infected cells are identified and destroyed by natural killer NK cells which are a type of lymphocyte that can kill cells infected with viruses or tumor cells abnormal cells that uncontrollably divide and invade other tissue. . Scientists at Cedars-Sinai Medical Center have discovered how a molecular receptor on the surface of white blood cells identifies when invading. By contrast extracellular. Many of the receptors and ligands involved in NK cell antimicrobial activity have been identified and we are beginning to. ...
