Natural Killer T-cells
Natural killer T (NKT) cells are a heterogeneous group of T cells that share properties of both T cells and natural killer (NK) cells. Many of these cells recognize the non-polymorphic CD1d molecule, an antigen-presenting molecule that binds self- and foreign lipids and glycolipids. Upon activation, NK T cells are able to produce large quantities of interferon-gamma, IL-4, and granulocyte-macrophage colony-stimulating factor, as well as multiple other cytokines and chemokines (such as IL-2 and TNF-alpha). NKT cells seem to be essential for several aspects of immunity because their dysfunction or deficiency has been shown to lead to the development of autoimmune diseases (such as diabetes or atherosclerosis) and cancers. NKT cells have recently been implicated in the disease progression of human asthma. The clinical potential of NKT cells lies in the rapid release of cytokines (such as IL-2, IFN-gamma, TNF-alpha, and IL-4) that promote or suppress different immune responses.
Liberty and Security
All aspire to liberty and security in their lives but few people truly enjoy them. This book explains why this is so. In what Conor Gearty calls our 'neo-democratic' world, the proclamation of universal liberty and security is mocked by facts on the ground: the vast inequalities in supposedly free societies, the authoritarian regimes with regular elections, and the terrible socio-economic deprivation camouflaged by cynically proclaimed commitments to human rights.
