Vigorous activation of monocytes in juvenile autoimmune liver disease escapes the control of regulatory T‐cells
Maria Serena Longhi, Ragai R. Mitry, Marianne Samyn, Astrid Scalori, Munther J. Hussain, Alberto Quaglia, Giorgina Mieli‐Vergani, Yun Ma, Diego Vergani – 23 June 2009 – Interface hepatitis, the histological lesion typical of autoimmune hepatitis (AIH), is composed of CD4 and CD8 T lymphocytes and of innate immunity cells, particularly monocytes. Studies in AIH have focused on autoreactive CD4 and CD8 T cells and impairment of CD4+CD25+ regulatory T cells (T‐regs), whereas little is known about the role of monocytes and their relationship with T‐regs.
