Cytotoxic immunological synapses. [PDF]
Summary: One of the most fundamental activities of the adaptive immune system is to kill infected cells and tumor cells. Two distinct pathways mediate this process, both of which are facilitated by a cytotoxic immunological synapse. While traditionally thought of as innate immune cells, natural killer (NK) cells are now appreciated to have the ...

The immune synapses reveal aberrant functions of CD8 T cells during chronic HIV infection
HIV infection over time is thought to result in premature aging and aberrant immune responses including the induction of immunological senescence. Here the authors show altered formation of immune synapses by naive CD8+ T cells and dysregulated synapse ...

Deterministic mechanical model of T-killer cell polarization reproduces the wandering of aim between simultaneously engaged targets [PDF]
T-killer cells of the immune system eliminate virus-infected and tumorous cells through direct cell-cell interactions. Reorientation of the killing apparatus inside the T cell to the T-cell interface with the target cell ensures specificity of the immune

LFA-1 Activation in T-Cell Migration and Immunological Synapse Formation
Integrin LFA-1 plays a critical role in T-cell migration and in the formation of immunological synapses. LFA-1 functions through interacting with its ligands with differing affinities: low, intermediate, and high.

Immune-mediated loss of transgene expression from virally transduced brain cells is irreversible, mediated by IFNγ, perforin, and TNFα, and due to the elimination of transduced cells [PDF]
The adaptive immune response to viral vectors reduces vector-mediated transgene expression from the brain. It is unknown, however, whether this loss is caused by functional downregulation of transgene expression or death of transduced cells.

The Immunological Synapse [PDF]
AbstractThe molecular interactions underlying regulation of the immune response take place in a nanoscale gap between T cells and antigen-presenting cells, termed the immunological synapse. If these interactions are regulated appropriately, the host is defended against a wide range of pathogens and deranged host cells.

The adaptive immune response is initiated by the interaction of T cell antigen receptors with major histocompatibility complex molecule-peptide complexes in the nanometer scale gap between a T cell and an antigen-presenting cell, referred to as an immunological synapse.

BackgroundAstrocytes usually respond to trauma, stroke, or neurodegeneration by undergoing cellular hypertrophy, yet, their response to a specific immune attack by T cells is poorly understood.

Identification of a synaptic vesicle-specific membrane protein with a wide distribution in neuronal and neurosecretory tissue. [PDF]
Two different monoclonal antibodies, characterized initially as binding synaptic terminal regions of rat brain, bind a 65,000-dalton protein, which is exposed on the outer surface of brain synaptic vesicles. Immunocytochemical experiments at the electron
