On The Role of Natural Killer Cells in Neurodegenerative Diseases
نویسنده
چکیده
Natural killer (NK) cells exert important immunoregulatory functions by releasing several inflammatory molecules, such as IFN-γ and members of chemokines, which include CCL3/MIP-1α and CCL4/MIP-1β. These cells also express heptahelical receptors, which are coupled to heterotrimeric G proteins that guide them into inflamed and injured tissues. NK cells have been shown to recognize and destroy transformed cells and virally-infected cells, but their roles in neurodegenerative diseases have not been examined in detail. In this review, I will summarize the effects of NK cells in two neurodegenerative diseases, namely multiple sclerosis and globoid cell leukodystrophy. It is hoped that the knowledge obtained from these diseases may facilitate building rational protocols for treating these and other neurodegenerative or autoimmune diseases using NK cells and drugs that activate them as therapeutic tools.

HLA-KIR Interactions and Immunity to Viral Infections
Host genetic factors play a central role in determining the clinical phenotype of human diseases. Association between two polymorphic loci in human genome, human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptors (KIRs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. Hence, defining the influence of genetic di...

Background: Pregnancy is a phenomenon that antigens of semi allogenic fetus are in direct contact with mother's immune system. Immune dysregulation can cause fetus rejection by mother's immune system responses. Human leukocyte antigen-G1, as an immunotolerant molecule has a major role to induce tolerance during pregnancy by suppression of natural killer cells through inhibitor receptors on thes...

Microglia is a type of glial cell located throughout the central nervous system (CNS), which is sensitive to CNS injury and disease. Responsibility of microglia as the resident macrophage cells for injuries suggests that these cells have the potential to act as diagnostic markers of disease beginning or progression. Function of Microglia is strongly synchronized by the microenvironment of brain...

Abstract Background & aim: Kynurenine pathway (KP) plays an important role in the pathogenesis of neuroinflammation and neurodegenerative disorders. In neurodegenerative diseases (NDD) such as Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's disease (HD) and Multiple sclerosis (MS), brain neurons are initially involved and gradually disappear. In the present review article, the ...
