The mechanism underlying this process, known as self-tolerance, is hitherto unresolved but seems to involve the control of clonal expansion of autoreactive lymphocytes. This article reviews mathematical modeling of self-tolerance, addressing two specific hypotheses. The first hypothesis posits that self-tolerance is mediated by tuning of activation thresholds, which makes autoreactive T lymphocytes reversibly &quot;anergic&quot; and unable to proliferate. The second hypothesis posits that the proliferation of autoreactive T lymphocytes is instead controlled by specific regulatory T lymphocytes. Models representing the population dynamics of autoreactive T lymphocytes according to these two hypotheses were derived. For each model we identified how cell density affects tolerance, and predicted the corresponding phase spaces and bifurcations. We show that the simple induction of proliferative anergy, as modeled here, has a density dependence that is only partially compatible with adoptive transfers of tolerance, and that the models of tolerance mediated by specific regulatory T cells are closer to the observations."}],"doi":"10.1016/j.cam.2004.10.025","publisher":"Elsevier","intvolume":"       184","title":"Immunological self tolerance: Lessons from mathematical modeling","day":"01","author":[{"last_name":"Carneiro","full_name":"Carneiro, Jorge","first_name":"Jorge"},{"last_name":"Paixao","orcid":"0000-0003-2361-3953","id":"2C5658E6-F248-11E8-B48F-1D18A9856A87","first_name":"Tiago","full_name":"Tiago Paixao"},{"first_name":"Dejan","full_name":"Milutinovic, Dejan","last_name":"Milutinovic"},{"last_name":"Sousa","first_name":"João","full_name":"Sousa, João"},{"first_name":"Kalet","full_name":"Leon, Kalet","last_name":"Leon"},{"last_name":"Gardner","full_name":"Gardner, Rui","first_name":"Rui"},{"last_name":"Faro","first_name":"Jose","full_name":"Faro, Jose"}],"publication_status":"published"}
