Abstract
An autoimmune disease is an inflammatory condition in which the human body’s immune
system attacks normal cells, resulting in decreased and abnormal immune function, which eventually
leads to tissue damage or organ dysfunction. In the field of medicine, especially in pediatrics, knowledge
about autoimmune diseases is still inadequate. Some common juvenile autoimmune diseases
such as Henoch–Schonlein purpura, systemic juvenile idiopathic arthritis, mucocutaneous lymph node
syndrome, and autoimmune encephalitis cause considerable public concern. Recent studies revealed
that heme oxygenase 1 (HO-1), an enzyme that participates in heme degradation, plays a critical role
in the pathogenesis and may regulate autoimmunity. Firstly, it may promote the differentiation of T
lymphocytes into CD4+CD25+ regulatory T cells and may be associated with changes in the ratios of
cytokines (Th1/Th2 and Th17/Treg) as well. Secondly, HO-1 can regulate the immune system through
the secretion of proteins such as transforming growth factors and interleukins. Moreover, increasing
the expression of HO-1 can improve vascular function by increasing antioxidant levels. Thus, HO-1
may provide a theoretical basis and guidance for therapeutic management of juvenile autoimmune diseases.
