A primary mediator for allergies is the aggregation of antigens and IgE antibodies bound to cell-surface receptors, Fc\u03b5RI. Antibody\/antigen aggregate formation causes stimulation of mast cells and basophils, initiating cellular degranulation and releasing immune mediators which produce an allergic or anaphylactic response. Understanding the shape and structure of these aggregates can provide critical insights into the allergic response. We have previously developed methods to geometrically model, simulate and analyze antibody aggregation inspired by rigid body robotic motion simulations. Our technique handles the large size and number of molecules involved in aggregation, providing an advantage over traditional simulations such as molecular dynamics (MD) and coarse-grained energetic models. In this paper, we study the impact of model resolution on simulations of geometric structures using both our previously developed Monte Carlo simulation and a novel application of rule-based modeling. These methods complement each other, the former providing explicit geometric detail and the latter providing a generic representation where multiple resolutions can be captured. Our exploration is focused on two antigens, a man-made antigen with three binding sites, DF3, and a common shrimp allergen (antigen), Pen a 1. We find that impact of resolution is minimal for DF3, a small globular antigen, but has a larger impact on Pen a 1, a rod-shaped molecule. The volume reduction caused by the loss in resolution allows more binding site accessibility, which can be quantified using a rule-based model with implicit geometric input. Clustering analysis of our simulation shows good correlation when compared with available experimental results. Moreover, collisions in all-atom reconstructions are negligible, at around 0.2% at 90% reduction.<\/jats:p>","DOI":"10.1017\/s0263574716000199","type":"journal-article","created":{"date-parts":[[2016,5,13]],"date-time":"2016-05-13T09:17:13Z","timestamp":1463131033000},"page":"1754-1776","source":"Crossref","is-referenced-by-count":7,"title":["Influence of model resolution on geometric simulations of antibody aggregation"],"prefix":"10.1017","volume":"34","author":[{"given":"Kasra","family":"Manavi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna","family":"Jacobson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brittany","family":"Hoard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia","family":"Tapia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2016,5,13]]},"reference":[{"key":"S0263574716000199_ref46","doi-asserted-by":"publisher","DOI":"10.1016\/j.sbi.2015.03.007"},{"key":"S0263574716000199_ref21","doi-asserted-by":"publisher","DOI":"10.1002\/prot.10115"},{"key":"S0263574716000199_ref50","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3495(92)81840-4"},{"key":"S0263574716000199_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S0097-8493(97)00082-4"},{"key":"S0263574716000199_ref26","doi-asserted-by":"publisher","DOI":"10.1021\/ja907125t"},{"key":"S0263574716000199_ref48","doi-asserted-by":"publisher","DOI":"10.1194\/jlr.E600002-JLR200"},{"key":"S0263574716000199_ref42","unstructured":"Autodesk Maya (2014) URL: http:\/\/www.autodesk.com\/."},{"key":"S0263574716000199_ref22","doi-asserted-by":"publisher","DOI":"10.1186\/1477-5956-11-S1-S6"},{"key":"S0263574716000199_ref35","doi-asserted-by":"publisher","DOI":"10.1021\/jp206527p"},{"key":"S0263574716000199_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3495(99)77456-4"},{"key":"S0263574716000199_ref51","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.175.12.8354"},{"key":"S0263574716000199_ref40","doi-asserted-by":"crossref","unstructured":"K.
