Abstract

IgG molecules exert both pro- and antiinflammatory effector functions based on the composition of the fragment crystallizable (Fc) domain glycan. Sialylated IgG Fc domains have antiinflammatory properties that are attributed to their ability to increase the activation threshold of innate effector cells to immune complexes by stimulating the upregulation of the inhibitory Fcγ receptor IIB (FcγRIIB). Here, we report that IgG Fc sialylation of human monoclonal IgG1 molecules impairs their efficacy to induce complement-mediated cytotoxicity (CDC). Fc sialylation of a CD20-targeting antibody had no impact on antibodydependent cellular cytotoxicity and did not change the affinity of the antibody for activating Fcγ receptors. In contrast, the presence of sialic acid abrogated the increased binding of C1q to Fc-galactosylated IgG1 and resulted in decreased levels of C3b deposition on the cell surface. Similar to monoclonal antibodies, sialic acid inhibited the increased C1q binding to galactosylated Fc fragments in human polyclonal IgG. In sera derived from patients with chronic inflammatory demyelinating polyneuropathy, an autoimmune disease of the peripheral nervous system in which humoral immune responses mediate tissue damage, induction of IgG Fc sialylation was associated with clinical disease remission. Thus, impairment of CDC represents an FcγR- independent mechanism by which Fc-sialylated glycovariants might limit proinflammatory IgG effector functions., Introduction IgG molecules can trigger both pro- and antiinflammatory responses mediated by their fragment crystallizable domain (Fc). Proinflammatory pathways include the activation of innate immune effector cells via cellular receptors [...]

Abstract

The inhibitory Fc-[gamma] receptor Fc[gamma]RIIB, expressed on myeloid and B cells, has a critical role in the balance of tolerance and autoimmunity, and is required for the antiinflammatory activity of intravenous Ig (IVIG) in various murine disease models. However, the function of Fc[gamma]RIIB and its regulation by IVIG in human autoimmune diseases are less well understood. Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common treatable acquired chronic polyneuropathy, and IVIG is widely used as a first-line initial and maintenance treatment. We found that untreated patients with CIDP, compared with demographically matched healthy controls, showed consistently lower Fc[gamma]RIIB expression levels on naive B cells, and failed to up-regulate or to maintain up-regulation of FcyRIIB as B cells progressed from the naive to the memory compartment. Concomitantly, the rare -386C/-120A Fc[gamma]RIIB promoter polymorphism resulting in reduced promoter activity previously associated with autoimmune phenotypes was overrepresented in CIDP. Also, Fc[gamma]RIIB protein expression was up-regulated on monocytes and B cells after clinically effective IVIG therapy. Thus, our results suggest that the inhibitory Fc[gamma]RIIB is impaired at a critical B cell differentiation checkpoint in CIDP, and that modulating Fc[gamma]RIIB expression might be a promising approach to efficiently limit antibody-mediated immunopathology in CIDP. autoimmunity | human | immunology | Fc receptor | CIDP

Abstract

Ghrelin, an orexigenic peptide, exerts immunomodulatory and other effects in the CNS and has neuroprotective properties. Ghrelin is predominantly produced by X/A-like cells in the gastric mucosa. Hence, ghrelin's main source of production lies outside the CNS while important functions of ghrelin are operated by specific receptors in the CNS. We analyzed 82 samples of our repository (45 samples form patients with multiple sclerosis and 37 control samples) for cerebrospinal fluid (CSF) and corresponding serum concentrations of ghrelin. Desacyl ghrelin concentrations were measured with a commercially available enzyme immunometric assay. We validated the assay for CSF samples. The test-retest reproducibility for ghrelin in CSF samples was excellent. Ghrelin CSF concentrations were higher in patients with multiple sclerosis (p<0.02) compared with controls. CSF concentrations correlated with serum concentrations in patients with multiple sclerosis (p<0.01). No such correlation was found in controls. Our findings endorse existing hypotheses that ghrelin affects the central inflammatory process in MS. The correlation between serum and CSF concentrations in MS, but not in controls, suggests a differential regulation of blood-to-brain transport mechanisms for ghrelin in MS and indicates that central effects of ghrelin in MS might be amenable to pharmacological manipulation of the systemic ghrelin secretion.
