Human mature dendritic cells (DCs) can efficiently stimulate natural killer (NK)-cell responses without being targeted by their cytotoxicity. To understand this important regulatory crosstalk, we characterized the development of the immunologic synapse ...

The Immunological Organ Environment Dictates the Molecular and Cellular Pathways of Cytotoxic Antibody Activity [PDF]
Cytotoxic immunoglobulin G antibodies are an essential component of therapeutic approaches aimed at depleting self-reactive or malignant cells. More recent evidence suggests that the tissue in which the target cell resides influences the underlying molecular and cellular pathways responsible for cytotoxic antibody activity.

Sensing Danger: Innate Immunology for Intrusion Detection [PDF]
The immune system provides an ideal metaphor for anomaly detection in general and computer security in particular. Based on this idea, artificial immune systems have been used for a number of years for intrusion detection, unfortunately so far with little success. However, these previous systems were largely based on immunological theory from the 1970s

NKp46 clusters at the immune synapse and regulates NK cell polarization
Natural killer cells play an important role in first-line defense against tumor and virus-infected cells. The activity of NK cells is tightly regulated by a repertoire of cell-surface expressed inhibitory and activating receptors.

Natural killer (NK) cells play an important immunologic role, targeting tumors and virus-infected cells; however, NK cells do not impede the progression of human immunodeficiency virus (HIV) infection.

Natural killer (NK) cells are innate immune lymphocytes that provide critical defense against virally infected and transformed cells. NK-cell cytotoxicity requires the formation of an F-actin rich immunologic synapse (IS), as well as the polarization of ...

Cytotoxic Isoantibodies and Immunologic Enhancement in Mice.
Summary1. Cytotoxic isoantibodies and hemagglutinins are stimulated in response to H-2 isoantigenic differences between graft and host in mice. 2. This study offers data correlating cytotoxic isoantibody and immunological enhancement. 3. The mechanism of immunological enhancement has been shown to be associated with peripheral as well as central ...

Estimation of In-Vitro Free Radical Scavenging and Cytotoxic Activities of Thiocarbohydrazones Derivatives [PDF]
Objective: To investigate free radical scavenging potential of thiocarbohydrazones derivatives for the discovery of antioxidant compounds of synthetic origin. Method: Eighteen thiocarbohydrazones derivatives were screened for antioxidant activities by using in vitro radical inhibition assay.

The Biological Influence and Clinical Relevance of Polymorphism Within the NKG2D Ligands
NKG2D is a major regulator of the activity of cytotoxic cells and interacts with eight different ligands (NKG2DL) from two families of MIC and ULBP proteins.

Production of Transgenic Cloned Miniature Pigs with Membrane-bound Human Fas Ligand (FasL) by Somatic Cell Nuclear Transfer [PDF]
Cell-mediated xenograft rejection, including NK cells and CD8+ CTL, is a major obstacle in successful pig-to-human xenotransplantation. Human CD8+ CTL and NK cells display high cytotoxicity for pig cells, mediated at least in part by the Fas/FasL pathway.
