“…An example of the second case is the genetic disease X-linked agammaglobulinemia, in which a lack of DC maturation has been reported. Addition of natural IgG and of autoreactive antibodies to DC from these patients results in their maturation, as assessed by upregulation of major histocompatibility complex class II and costimulatory molecules (3). B. abortus resides in DC in vivo, and mouse DC are able to kill virB mutants (4,36).…”

“…29 Previous studies have shown that IVIg can modulate diverse lymphoid and myeloid cell populations. 30,31 Thus, at therapeutic concentrations used in autoimmune diseases (0.15 mM), IVIg induces a downmodulation of monocyte-derived DC, which in turn fail to support T-cell proliferation. 30 We asked whether the mechanism whereby IVIg leads to an expansion of Treg is central to the protection against EAE or if it is a mere bystander effect.…”

“…Studies on patients with common variable immunodeficiency (CVID), a heterogeneous disorder associated with low serum immunoglobulin concentrations, 18 suggest that their DCs are defective and that this, at least in part, is due to the low levels of serum antibodies. [19][20][21] Treatment with intravenous immunoglobulin (IVIg) to increase immunoglobulin levels has been beneficial in preventing infections in CVID patients, although the exact mechanism of IVIg treatment is not completely understood. 22 It has recently been suggested that the clinical effect of IVIg treatment in autoimmune disease involves the interaction of IVIg with activating Fc␥ receptors on DCs.…”
