In recent years, there has been growing realization that the large-scale spatial arrangement of cell surface receptors can regulate the outcome of ensuing signal transduction process.  Signaling through the T cell receptor (TCR) in the context of the immunological synapse provides a case in point.  Spatial reorganization of TCRs occurs on multiple length-scales, and apparently with multiple purposes, during antigen recognition by T cells.  The cell membrane and cytoskelton, working as an inseparable unit in this case, create the mechanical framework within which TCR signaling processes occur.  To better study these phenomena, a new experimental strategy, in which the spatial positions of cell membrane receptors are directly manipulated through mechanical means, has emerged.  By physically inducing a ?spatial mutation? of the signaling apparatus, the role of spatial organization in signal transduction as well as the mechanisms by which it arises can be illuminated.  Specific applications of this strategy to TCR signaling will be discussed. \n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:christine.payne@chemistry.gatech.edu\u0022\u003EDr. Christine Payne\u003C\/a\u003E (404-385-3125).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"AACP seminar series - Prof. Jay Groves, UC Berkeley\n\nMechanics of signal transduction in cell membranes","format":"limited_html"}],"field_summary_sentence":[{"value":"AACP seminar series - Prof. Jay Groves, UC Berkeley"}],"uid":"27275","created_gmt":"2007-03-09 01:00:00","changed_gmt":"2016-10-08 01:57:28","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-11-06T18:30:00-05:00","event_time_end":"2007-11-06T20:00:00-05:00","event_time_end_last":"2007-11-06T20:00:00-05:00","gmt_time_start":"2007-11-06 23:30:00","gmt_time_end":"2007-11-07 01:00:00","gmt_time_end_last":"2007-11-07 01:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/chem.berkeley.edu\/people\/faculty\/groves\/groves.html","title":"Prof. Jay Groves, UC Berkeley"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
