NK, NKT and Invariant-NKT Cells in Tumor Draining Lymph Nodes of Patients with Breast Cancer
Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...
متن کاملNKT cells reject islets
The TIM (T cell immunoglobulin mucin) proteins have emerged as key regulators of allergic and autoimmune diseases due to their influence on T helper (Th)-1 and Th-2 responses. On page 955, Chen and colleagues show that one member of this family, TIM-2, multitasks as a receptor for H-ferritin, a component of the iron storage protein ferritin. Ferritin was not what the group expected to find when...
متن کاملTrouble-making NKT cells
The dark side of NKT cells is revealed in a new study showing that they contribute to autoimmune arthritis in mice. On page 41, Kim et al. find that arthritis is worse in joints that are invaded by NKT cells. NKT cells are innate immune cells that express both NK and T cell markers, and are protective in many other models of autoimmune disease. The authors tested NKT function in K/BxN mice—an e...
متن کاملInvariant NKT cells
Although invariant natural killer T (iNKT) cells influence antitumor responses indirectly by secreting cytokines and promoting the cytolytic functions of T and NK cells, we find that iNKT cells mediate direct tumoricidal activity in vitro and significantly inhibit tumor growth in vivo, even in the absence of other cytotoxic lymphocytes.
متن کاملNKT Cells in Sepsis
Sepsis is currently a leading cause of death in hospital intensive care units. Previous studies suggest that the pathophysiology of sepsis involves the hyperactivation of complex proinflammatory cascades that include the activation of various immune cells and the exuberant secretion of proinflammatory cytokines by these cells. Natural killer T-cells (NKTs) are a sublineage of T cells that share...
