[TD]It is known that viral infections can cause acute, chronic, and autoimmune diseases (ADs). However, the mechanism of how a persistent viral infection contributes to ADs remains still unclear. In this thesis, pathological and immunological aspects of how common viruses can initiate autoimmunity were investigated, and human parvovirus B19 (B19V) was employed as a model virus. B19V non-structural protein 1 (NS1), a superfamily 3 (SF3) helicase, initiated DNA damage resulting in cellular apoptosis. The apoptotic bodies (ApoBods) induced by B19V NS1 were purified and characterized. These ApoBods contained viral NS1 proteins with modified autoimmune-associated self-antigens, e.g. DNA, Smith, Apolipoprotein H, and histone 4. Subsequently, in vitro B19V-induced ApoBods were phagocytized by macrophages that produced pro- inflammatory cytokines and chemokines such as sICAM-1, IL-8, TNF-Į, and IFN-Ȗ. Furthermore in vivo, the properties of viral-induced ApoBods causing immune ...[/TD]
