Opposing effects of PKCtheta and WASp on symmetry breaking and relocation of the immunological synapse.
The immunological synapse (IS) is a junction between the T cell and antigen-presenting cell and is composed of supramolecular activation clusters (SMACs). No studies have been published on naive T cell IS dynamics. Here, we find that IS formation during antigen recognition comprises cycles of stable IS formation and autonomous naive T cell migration. The migration phase is driven by PKCtheta, w...

متن کاملImmunological Synapses: Breaking Up May Be Good to Do
Activated T cells form stable immunological synapses with antigen-presenting cells whereas naïve T cells initially engage in more transient interactions. Sims et al. (2007) demonstrate that these transient interactions are due to the kinase PKCtheta, which serves to destabilize the synapse thereby permitting T cells to migrate elsewhere. They also show that re-establishment of a synapse involve...
متن کاملA Computational Study to Find the Vibrational Modes Connected with Specific Molecular Structures of Calculated Compound
The purpose of this research is to provide a deeper understanding of the planar high- symmetry configuration instability. In the ideal case, the distortion corresponds to the movements of nuclei along normal modes that belong to non-totally symmetric irreps of the high symmertry (HS) point group of molecule. The analysis of the structural distortion from the HS nuclear arrangements of the JT ac...
متن کاملCell adhesion molecules and actin cytoskeleton at immune synapses and kinapses.
The immunological synapse is a stable adhesive junction between a polarized immune effector cell and an antigen-bearing cell. Immunological synapses are often observed to have a striking radial symmetry in the plane of contact with a prominent central cluster of antigen receptors surrounded by concentric rings of adhesion molecules and actin-rich projections. There is a striking similarity betw...
