Mechanisms governing tolerance

  1. Focus on the mechanisms governing tolerance to self: elimination of autoreactive clones during
    lymphocyte development; induction of ‘anergy’; function of regulatory T cells (Tregs);
    engagement of inhibitory molecules such as CTLA-4. Gene variants that abrogate or impair the
    function of these regulatory processes should be at least mentioned.
  2. Focus on genetic susceptibility to autoimmune disease. This focus can be seen as a
    variation/extension of point 1 and should focus on susceptibility genes that have been identified
    in family studies and genome-wide association studies (GWAS), including HLA and non-HLA
    genes.
  3. Focus on environmental factors which are thought to act as triggers of autoimmune attack in
    susceptible people. These should include the role of viral infections (of which a focus of its own
    could be ‘long Covid’ and autoimmunity); sex hormones; microbiome imbalance

  4. Focus on a particular disease, e.g., multiple sclerosis or type I diabetes. In this focus, your
    paper should provide context by including an introduction where points 1-3 are summarized in
    half to one page.
  5. A ‘holistic approach’ where points 1-3 are all explored in some depth, as per word limits.
  6. Focus on the treatment of autoimmune disease. In this focus, your paper should provide context
    by including an introduction where points 1-3 are summarized in half to one page. It can include:
    A. conventional immunosuppressive therapy; B. monoclonal antibodies targeting specific selfantigens, blocking inflammatory cytokines, blocking immune cell trafficking, blocking costimulatory pathways; C. therapies to restore tolerance; D. more experimental therapies
    including the creation of personalized Tregs.
