Opposing Actin Networks Modulate The Mechano-Activation Of The Integrin Lfa-1 During Immunological Synapse Formation, William Andrew Comrie
Publicly Accessible Penn Dissertations
Formation of a functional immune response requires the regulated transfer of information between T cells, and APCs, which leads to a variety of functional outcomes. In many cases this information transfer occurs at a regulated area of cell - cell contact termed the immunological synapse (IS). In T cells responding to APCs there is a robust accumulation of F-actin on the T cell side of the synapse. This F-actin response is characterized by robust polymerization at the periphery of the contact site followed by centripetal flow of the network towards the center of the IS. While it is well known that ...
