Widespread amyloidogenicity potential of multiple myeloma patient-derived immunoglobulin light chains [PDF]
BMC Biology, 2023 Background In a range of human disorders such as multiple myeloma (MM), immunoglobulin light chains (IgLCs) can be produced at very high concentrations. This can lead to pathological aggregation and deposition of IgLCs in different tissues, which in turn

Inhibition by small-molecule ligands of formation of amyloid fibrils of an immunoglobulin light chain variable domain [PDF]
eLife, 2015 Overproduction of immunoglobulin light chains leads to systemic amyloidosis, a lethal disease characterized by the formation of amyloid fibrils in patients' tissues. Excess light chains are in equilibrium between dimers and less stable monomers which can

Systemic immunoglobulin light chain amyloidosis [PDF]
Nature Reviews Disease Primers, 2018 Systemic immunoglobulin light chain amyloidosis is a protein misfolding disease caused by the conversion of immunoglobulin light chains from their soluble functional states into highly organized amyloid fibrillar aggregates that lead to organ dysfunction.

Individual B cells transcribe multiple rearranged immunoglobulin light chains in teleost fish [PDF]
iScience, 2021 Summary: B cells express a unique antibody protein which comprises two pairs of immunoglobulin (Ig) heavy (H) and light (L) chains. In addition to an invariable constant (C) region, IgH and IgL chains encompass a variable (V) region mediating antigen ...

Urine and Free Immunoglobulin Light Chains as Analytes for Serodiagnosis of Hantavirus Infection [PDF]
Viruses, 2019 Rapid point-of-care testing is a megatrend in infectious disease diagnosis. We have introduced a homogeneous immunoassay concept, which is based on the simultaneous binding of antigen and protein L to a given immunoglobulin molecule.

Immunoglobulin light chains in medaka (Oryzias latipes). [PDF]
Immunogenetics, 2013 The gene segments encoding antibodies have been studied in many capacities and represent some of the best-characterized gene families in traditional animal disease models (mice and humans). To date, multiple immunoglobulin light chain (IgL) isotypes have been found in vertebrates and it is unclear as to which isotypes might be more primordial in nature.

Immunoglobulin light chain amyloidosis [PDF]
memo - Magazine of European Medical Oncology, 2021 SummaryImmunoglobulin light chain (AL) amyloidosis is a rare and underdiagnosed life-threatening systemic disease, primarily caused by insoluble depositions of misfolded monoclonal light chains. The monoclonal light chain paraprotein originates from a small clonal B‑cell or a clonal plasma cell population.

Different roles of urinary light chains and serum light chains as potential biomarkers for monitoring disease activity in systemic lupus erythematosus [PDF]
PeerJ, 2022 Objective The assessment system for monitoring systemic lupus erythematosus (SLE) disease activity is complex and lacks reliable laboratory indicators. It is necessary to find rapid and noninvasive biomarkers.

Some structural features of the peptide profile of myelin basic protein-hydrolyzing antibodies in schizophrenic patients [PDF]
PeerJ, 2023 The antibodies of schizophrenic patients that hydrolyze myelin basic protein (MBP) have been actively studied recently, but the mechanism of the catalytic properties of immunoglobulin molecules remains unknown.

Antibody Light Chains: Key to Increased Monoclonal Antibody Yields in Expi293 Cells?
Antibodies, 2022 When constructing isogenic recombinant IgM–IgG pairs, we discovered that μ heavy chains strongly prefer partnering with λ light chains for optimal IgM expression in transiently cotransfected Expi293 cells.
