Cytoskeletal actin patterns shape mast cell activation

Self-organizing actin patterns shape cytoskeletal cortex organization

Living systems rely, for biological function, on the spatiotemporal organization of their structures. Cellular order naturally emerges by dissipation of energy. Consequently, energy-consuming processes operating far from thermodynamic equilibrium are a necessary condition to enable biological systems to respond to environmental cues that allow their transitions between different steady-states. ...

Mast cell activation syndrome

www.amepc.org/tau © Translational Andrology and Urology. All rights reserved. It has been over 30 years since the Interstitial Cystitis Association of America (ICA) was established in 1984. Although a great deal more is understood about interstitial cystitis/bladder pain syndrome (IC/BPS), the cause and cure of this condition remains unknown. One hypothesis regarding etiology that appears to ha...

Mast Cell Activation Syndromes

Actin cytoskeletal dynamics in T lymphocyte activation and migration.

Dynamic rearrangements of the actin cytoskeleton are crucial for the function of numerous cellular elements including T lymphocytes. They are required for migration of T lymphocytes through the body to scan for the presence of antigens, as well as for the formation and stabilization of the immunological synapse at the interface between antigen-presenting cells and T lymphocytes. Supramolecular ...

Cytoskeletal actin dynamics shape a ramifying actin network underpinning immunological synapse formation

T cell activation and especially trafficking of T cell receptor microclusters during immunological synapse formation are widely thought to rely on cytoskeletal remodeling. However, important details on the involvement of actin in the latter transport processes are missing. Using a suite of advanced optical microscopes to analyze resting and activated T cells, we show that, following contact for...
