Clonal Immunoglobulin against Lysolipids in the Origin of Myeloma

Open access

Abstract

Summ a r yAntigen-driven selection has been implicated in the pathogenesis of monoclonal gammopathies.Patients with Gaucher's disease have an increased risk of monoclonal gammopathies.Here we show that the clonal immunoglobulin in patients with Gaucher's disease and in mouse models of Gaucher's disease-associated gammopathy is reactive against lyso-glucosylceramide (LGL1), which is markedly elevated in these patients and mice.Clonal immunoglobulin in 33% of sporadic human monoclonal gammopathies is also specific for the lysolipids LGL1 and lysophosphatidylcholine (LPC).Substrate reduction ameliorates Gaucher's disease-associated gammopathy in mice.Thus, longterm immune activation by lysolipids may underlie both Gaucher's disease-associated gammopathies and some sporadic monoclonal gammopathies.M ultiple myeloma and monoclonal gammopathy of undetermined significance (MGUS) are characterized by clonal expansion of transformed plasma cells. 1 Analyses of immunoglobulin genes in tumor cells have provided evidence of antigen-driven selection, with restricted heavy-chain variableregion use and highly hypermutated immunoglobulin heavy-and light-chain genes. [2][3]][4][5][6] However, the antigens underlying the origins of most MGUS and myeloma clones remain unknown.Hyperphosphorylated modification of stomatin (EPB72)-like 2 protein (STOML2, which is identical to paratarg-7) due to the inactivation of protein phosphatase 2A was identified as a target of certain paraproteins and an inherited risk factor for the development of gammopathies.[7][8][9] A recent study identified sumoylated heat-shock protein 90 as another inherited risk factor for plasma-cell dyscrasia.10 However, there remains a need to identify the antigenic origins of MGUS and myeloma that may be amenable to targeted prevention.Lipids (such as pristane) were implicated in the earliest models of murine plasmacytoma, 11 and lipid disorders such as Gaucher's disease and obesity are associated with an increased risk of myeloma.12,13 The risk of myeloma is markedly higher among patients with Gaucher's disease, in whom myeloma is now emerging as a leading cause of cancer-related death, than in the general population.13 Glucocerebrosidase deficiency in Gaucher's disease leads to increases in the level of LGL1.14 Recently, we identified a subset of human and murine LGL1-specific CD1d-restricted type 2 natural killer T cells that constitutively expressed markers of follicular helper T cells and helped in the differentiation of lipid-reactive plasma cells.15 In an earlier study, we found an elevation of type 2 natural killer T cells against another bioactive lysolipid, LPC, in myeloma.16 These studies led us to test whether the clonal immunoglobulin in Gaucher's disease-associated myeloma and sporadic myeloma was reactive against LGL1 and LPC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
