Localization, analysis and evolution of transposed human immunoglobulin VK genes [PDF]

open access: yes, 1988
The localization of Vκ gene regions to chromosome 2, on which the κ locus is located, and to other chromosomes is described. The Vκ genes that have been transposed to other chromosomes are called orphons.

Role of FibroScan in evaluating hepatic involvement in systemic amyloidosis: a single‐centre prospective pilot study

open access: yesInternal Medicine Journal, EarlyView.
Abstract Background Amyloidosis encompasses a group of diseases characterised by extracellular deposition of misfolded protein fibrils, potentially leading to organ dysfunction. Liver involvement occurs via direct amyloid infiltration, common in immunoglobulin light chain (AL) amyloidosis, or congestive hepatopathy, more typical in transthyretin (ATTR)

Critical Management Strategies for Cardiovascular Involvementin Light Chain Amyloidosis

open access: yes罕见病研究, 2023
Light chain amyloidosis (AL) is a kind of rare disease. The misfolding of the light chain of monoclonal immunoglobulin forms amyloid substances and deposit in different tissues and organs, resulting in organ dysfunction.

A Case of Severe Cholestasis due to Hepatic AL Amyloidosis

open access: yesGE: Portuguese Journal of Gastroenterology, 2019
Introduction: Immunoglobulin light chain-associated amyloidosis results from extracellular tissue deposition of fibril-forming monoclonal immunoglobulin light chains, secreted by a clone of plasma cells.

Localized Gastrointestinal Light Chain (AL) Amyloidosis Under Surveillance for Five Years: A Case Report

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Amyloidosis, characterized by the deposition of abnormal protein fibrils in organs, is classified as systemic or localized. Amyloid light chain (AL)‐type localized amyloidosis is uncommon, particularly when confined to the gastrointestinal tract.

POEMS Syndrome: 2026 Update on Diagnosis, Risk‐Stratification, and Management

open access: yesAmerican Journal of Hematology, Volume 101, Issue 10, Page 2632-2651, October 2026.
ABSTRACT Disease Overview POEMS syndrome is a life‐threatening syndrome due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyneuropathy, clonal plasma cell disorder (PCD), sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease.

Amyloidosis – short review

open access: yesJournal of Medical Science, 2016
Amyloidosis is a heterogeneous group of disorders associated with pathological deposition of amyloid. We can recognize two major categories of amyloidosis: primary (AL) and secondary (AA) type.

Increased Serum Free Light Chains Precede the Presentation of Immunoglobulin Light Chain Amyloidosis [PDF]

open access: yesJournal of Clinical Oncology, 2014
Purpose Patients with immunoglobulin light chain amyloidosis (AL amyloidosis) generally present with advanced organ dysfunction and have a high risk of early death. We sought to characterize monoclonal immunoglobulin (M-Ig) light chains before clinical presentation of AL amyloidosis.

Young Adult Microglial Deletion of C1q Reduces Engulfment of Synapses and Partially Mitigates Cognitive Impairment in an Aggressive Alzheimer's Disease Mouse Model

open access: yesGlia, Volume 74, Issue 9, September 2026.
Young adult deletion of microglial C1q reduced engulfment of Vglut1+ synapses and mitigated spatial cognitive deficits at 10 months of age in the amyloidopathy Arctic mouse model of AD. Neither fibrillar amyloid plaques nor soluble or insoluble Aβ levels in the hippocampus were affected by young adult microglial loss of C1q despite reduced phagocytosis

Clonotypic characterization defines B‐cell drivers of clonal expansion and intratumor heterogeneity in IgM monoclonal gammopathies

open access: yesHemaSphere, Volume 10, Issue 9, September 2026.
Abstract Waldenström macroglobulinemia (WM) and IgM monoclonal gammopathy of undetermined significance (MGUS) share the same cell of origin but differ in clonal size. Compared with other B‐cell neoplasms, the lymphoplasmacytic clone in WM can be rather small, limiting our understanding of clonal expansion.
