BACKGROUND Human intravenous immunoglobulin (IVIg) preparations are used for the treatment of autoimmune and allergic diseases. Natural autoantibodies are believed to contribute to IVIg-mediated anti-inflammatory effects. OBJECTIVE To address the question of whether IVIg preparations contain anti-sialic acid-binding Ig-like lectin-8 (anti-Siglec-8)(More)
Human intravenous immunoglobulin (IVIg) preparations are increasingly used for the treatment of autoimmune diseases. Earlier work demonstrated the presence of autoantibodies against Fas in IVIg, suggesting that IVIg might be able to induce caspase-dependent cell death in Fas-sensitive cells. In this study, we demonstrate that sialic acid-binding Ig-like(More)
BACKGROUND Specificities for carbohydrate IgG antibodies, thought to be predominantly of the IgG2 subclass, have never been broadly examined in healthy human subjects. OBJECTIVE To examine commercial intravenous immunoglobulin (IVIG) preparations for their ability to recognize a wide range of glycans and to determine the contribution of IgG2 to the(More)
Peripheral blood contains two major particular infrequent dendritic cells (DC) subsets linking the innate and specific immune system, the myeloid DC and plasmacytoid DC equivalent to the natural interferon-producing cells (NIPC). The functional characterization of these cells demands large volumes of blood, making a large animal model more appropriate and(More)
BACKGROUND Intravenous immunoglobulin (IVIG) preparations are increasingly used for the treatment of autoimmune and chronic inflammatory diseases. Naturally occurring autoantibodies against Siglec-9 and Fas are thought to contribute to the anti-inflammatory effects of IVIG via cell death regulation of leukocytes and tissue cells. Dimeric IVIG fractions are(More)
One major challenge of hypertension management is to achieve a compliance rate as high as possible in order to guarantee a successful long-term antihypertensive therapy. Clinical studies have shown that the drop-out rate may represent an indirect parameter for patient compliance. As having a negative influence on long-term compliance drug related side(More)
Alterations in circadian blood pressure rhythm have been described in patients with sleep apnea syndrome or arterial hypertension. Epidemiologic data indicate an association of circadian blood pressure rhythm and obstructive snoring; however, only little is known about effects of apneic phases during sleep on arterial hypertension and their relevance for(More)
Therapeutic intravenous immunoglobulin (IVIg) preparations contain antibodies reflecting the cumulative antigen experience of the donor population. IVIg contains variable amounts of monomeric and dimeric IgG, but there is little information available on their comparative antibody specificities. We have isolated highly purified fractions of monomeric and(More)
Intravenous immunoglobulin (IVIg) preparations are derived from pooled plasma from up to 60,000 healthy human donors and reflect the immunologic experience of the donor population. IVIg contains monomeric and dimeric IgG populations which are in a dynamic equilibrium depending on concentration, pH, temperature, donor pool size, time and stabilizers added in(More)
The macrophage (Mø) is an essential immune cell for innate immunity. Such cells are targeted by African swine fever virus (ASFV). The early phases of infection with ASFV have been previously characterized in non-leukocyte cells such as Vero cells. Here, we report on several additional key parameters that ASFV utilizes during the infection of primary Mø.(More)
