In particular, short amyloid oligomers inject themselves into the membranes of these cells and create pores that disrupt the strictly controlled flow of ions through the membranes. This leads to cell death. Getting rid of the short oligomers either by a deconstruction process or by elongating them into longer fibrils will reduce this toxicity and allow the \u03b2-cells to live longer.<\/jats:p>\n               <jats:p>Results: We develop a computational method to probe the binding affinity of amyloid structures and produce an amylin analog that binds to oligomers and extends their length. The binding and extension lower toxicity and \u03b2-cell death. The amylin analog is designed through a parsimonious selection of mutations and is to be administered with the pramlintide drug, but not to interact with it. The mutations (T9K L12K S28H T30K) produce a stable native structure, strong binding affinity to oligomers, and long fibrils. We present an extended mathematical model for the insulin\u2013glucose relationship and demonstrate how affecting the concentration of oligomers with such analog is strictly coupled with insulin release and \u03b2-cell fitness.<\/jats:p>\n               <jats:p>Availability and implementation: SEMBA, the tool to probe the binding affinity of amyloid proteins and generate the binding affinity scoring matrices and R-scores is available at: http:\/\/amyloid.cs.mcgill.ca<\/jats:p>\n               <jats:p>Contact: \u00a0jeromew@cs.mcgill.ca<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btv143","type":"journal-article","created":{"date-parts":[[2015,3,17]],"date-time":"2015-03-17T00:26:10Z","timestamp":1426551970000},"page":"2294-2302","source":"Crossref","is-referenced-by-count":4,"title":["Probing the binding affinity of amyloids to reduce toxicity of oligomers in diabetes"],"prefix":"10.1093","volume":"31","author":[{"given":"Mohamed Raef","family":"Smaoui","sequence":"first","affiliation":[{"name":"1 School of Computer Science and"},{"name":"2 McGill Center for Bioinformatics, McGill University, Montreal, QC, Canada and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henri","family":"Orland","sequence":"additional","affiliation":[{"name":"3 Institut de Physique Th\u00e9orique, CEA-Saclay, 91191 Gif\/Yvette Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00e9r\u00f4me","family":"Waldisp\u00fchl","sequence":"additional","affiliation":[{"name":"1 School of Computer Science and"},{"name":"2 McGill Center for Bioinformatics, McGill University, Montreal, QC, Canada and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,3,15]]},"reference":[{"key":"2023020202153537900_btv143-B1","doi-asserted-by":"crossref","first-page":"783","DOI":"10.1152\/jappl.1961.16.5.783","article-title":"Coefficients of normal blood glucose regulation","volume":"16","author":"Bolie","year":"1961","journal-title":"J.
