Although anti-GBM disease is seen as a prototypic autoantibody-mediated disease, T cells have a vital role in disease initiation and progression. T cells enhance B-cell function and antibody production and may play a direct pathogenic role in kidney and lung injury. [13] Autoreactive T cells against alpha3(IV)NC1 are rare in healthy individuals, owing to thymic deletion during fetal development. Autoreactive T cells in patients may form as a consequence of exposure of neoepitopes, altered antigen processing allowing pathogenic epitopes to be presented, or altered T-cell regulation. [12]
