Broadly neutralizing antibodies (bnAbs) are encouraging targets for such vaccines, because they can bind to diverse strains of these pathogens. BnAbs typically develop only after the immune system has been exposed to many mutated versions of a pathogen, and then too in few people and low numbers. Thus, sequentially administering multiple different pathogen-like proteins is a promising strategy to elicit bnAbs through vaccination. However, it remains unclear how best to design\/administer these proteins. We explore this using physics-based simulations and provide mechanistic insights into antibody evolution that could guide creation of universal vaccines against highly mutable pathogens.<\/jats:p>","DOI":"10.1073\/pnas.1919329117","type":"journal-article","created":{"date-parts":[[2020,8,3]],"date-time":"2020-08-03T20:28:27Z","timestamp":1596486507000},"page":"20077-20087","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":60,"title":["Optimizing immunization protocols to elicit broadly neutralizing antibodies"],"prefix":"10.1073","volume":"117","author":[{"given":"Kayla G.","family":"Sprenger","sequence":"first","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joy E.","family":"Louveau","sequence":"additional","affiliation":[{"name":"Harvard\u2013MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2715-0781","authenticated-orcid":false,"given":"Pranav M.","family":"Murugan","sequence":"additional","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arup K.","family":"Chakraborty","sequence":"additional","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139;"},{"name":"Department of Chemical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139;"},{"name":"Department of Physics, Massachusetts Institute of Technology, Cambridge, MA 02139;"},{"name":"Ragon Institute of MGH, MIT and Harvard, Cambridge, MA 02139;"},{"name":"Department of Chemistry, Massachusetts Institute of Technology, Cambridge, MA 02139"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2020,8,3]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1093\/bmb\/58.1.19"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-065X.2012.01124.x"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-immunol-020711-075032"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.immuni.2016.09.001"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.180.1.157"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/nri3803"},{"key":"e_1_3_4_7_2","doi-asserted-by":"crossref","first-page":"5155","DOI":"10.4049\/jimmunol.158.11.5155","article-title":"Somatic mutation leads to efficient affinity maturation when centrocytes recycle back to centroblasts","volume":"158","author":"Oprea M.","year":"1997","unstructured":"M.
