Te wyzwania of Autoimmunole Destruction

I), że destruction of beta cells is a sudden event a progressive process mediatd by a misdirected adaptative immete response. Autoreactive CD4 + (helper) and CD8 + (cytotoksyc) T lymphocytes recoverze specific betacell antigens such as insulin, glutamic acid decarboxylase (GAD), insulinomaatd antigentio -2 (IA2), and zintrablin

Once activated, CD8 + T cells infiltrate thee islets directly kill beta cells thrigh granizme andperforin release. CD4 + T cells provide help to B lymphocytes, which produce autoantibodie (a hallmark of precinical T1D), further amplifilying thee imty attack. Thee process is sustained to a breakd of central and perspediseral tolerance mechanisms.

Current treatments such as exogenous insulion therapy do nothing to reversy thi autoimte milieu. Even intensive insulin therapy cannot completely halt the residuate activity that may destrucy any equiing functional beta cells. Thus, a true cure must addicts both thee autoimty attack and thee need to recore or regenerate lost beta cell mass. Immune system reprogramming offers thee prospect of requiing thee first goail - permanently silenting thee destruvete imte response.
