Intrinsic toxicity of LCDD monoclonal Ig free light chain on plasma cells (PC)

Project description:We analyzed the transcriptome (RNA-seq) of mouse plasma cells (PC) expressing a human Ig light chain from a patient suffering light chain deposition disease (LCDD) as compared to control plasma cells (WT and DH-LMP2A, the latter producing no complete immunoglobulins, only free Ig light chains). Ig light chains causing LCDD present structural peculiarities leading to their aggregation and deposition into tissues and organs, mainly the kidney. We sought to determine if plasma cells producing these abnormal Ig could present specific phenotypes. The aim of the present study is to analyse the transcriptomic signature of plasma cells producing abnormal Ig free light chains.

Toxicity of LCDD monoclonal Ig free light chains on renal glomeruli

Project description:We analyzed the transcriptome (RNA-seq) of glomeruli in a mouse model of light chain deposition disease (LCDD) as compared to control mice (WT and DH-LMP2A, the latter producing no complete immunoglobulins, only free Ig light chains). Kidney lesions in LCDD are due to the deposition of an abnormal monoclonal free Ig light chain and comprise progressive thickening of basement membranes (tubular and glomerular) and nodular glomerulosclerosis resembling the lesions observed in diabetic nephropathy. The aim of the present study is to analyse the transcriptomic changes at early steps of glomerulosclerosis.

High throughput sequencing of immunoglobulin (Ig) heavy (IgH) and light (IgL) chain repertoires

Project description:We used 454 sequencing to assess the repertoire of B cell subsets from bone marrow, spleen, and small intestinal lamina propria from two mouse strains. We used a RAG2-GFP reporter mouse strain (129Sve background) to isolate CD19+ RAG2+ B lineage cells from bone marrow and small intestinal lamina propria and total splenic B cells. We used 5' RACE to amplify cDNA libraries using primers specific for the mu constant region of IgH and the Ig kappa constant region. We also used this technique to analyze total B cell libraries from Swiss Webster germ-free mice to compare to littermate controls that were cohoused with regular specific pathogen free (SPF) mice for 7 days. Examination of the Ig kappa repertoire and IgH repertoire in RAG2+ bone marrow B lineage cells compared to RAG2+ small intestinal lamina propria B lineage cells or total splenic B cells. There are 8 (Ig kappa) or 4 (IgH) independent experiments comparing repertoires in RAG2-GFP mice. Each experiment in RAG2-GFP+ mice consisted of a pool of 8-12 mice. There are 3 experiments comparing germ-free to colonized mouse total B cell repertoires, each consisting of one mouse per condition.

Understanding Mesangial Pathobiology in AL-Amyloidosis and Monoclonal Ig Light Chain Deposition Disease.

Project description:Patients with plasma cell dyscrasias produce free abnormal monoclonal Ig light chains that circulate in the blood stream. Some of them, termed glomerulopathic light chains, interact with the mesangial cells and trigger, in a manner dependent of their structural and physicochemical properties, a sequence of pathological events that results in either light chain-derived (AL) amyloidosis (AL-Am) or light chain deposition disease (LCDD). The mesangial cells play a key role in the pathogenesis of both diseases. The interaction with the pathogenic light chain elicits specific cellular processes, which include apoptosis, phenotype transformation, and secretion of extracellular matrix components and metalloproteinases. Monoclonal light chains associated with AL-Am but not those producing LCDD are avidly endocytosed by mesangial cells and delivered to the mature lysosomal compartment where amyloid fibrils are formed. Light chains from patients with LCDD exert their pathogenic signaling effect at the cell surface of mesangial cells. These events are generic mesangial responses to a variety of adverse stimuli, and they are similar to those characterizing other more frequent glomerulopathies responsible for many cases of end-stage renal disease. The pathophysiologic events that have been elucidated allow to propose future therapeutic approaches aimed at preventing, stopping, ameliorating, or reversing the adverse effects resulting from the interactions between glomerulopathic light chains and mesangium.
