Uncovering diversity in the immunoglobulin heavy chain locus. [PDF]

Cell Genom
The immunoglobulin heavy chain constant (IGHC) locus houses genetic determinates of antibody function and specificity. In this issue of Cell Genomics, Jana et al. use long-read sequencing to characterize extensive inter-individual diversity in the IGHC region across ancestrally diverse populations, highlighting potential functional consequences.

Gamma heavy chain disease associated with T-cell large granular lymphocyte lymphoproliferative disorder: case report and literature review.

Mediterranean Journal of Hematology and Infectious Diseases, 2023
Heavy chain diseases are rare B-cell neoplasms consisting of the production of a monoclonal immunoglobulin composed of the only heavy chain without corresponding light chains.

A Hands-on Activity for V(D)J Recombination in an Undergraduate Immunology Class

Journal of Microbiology & Biology Education, 2023
This learning activity teaches the difficult concept of V(D)J recombination as it occurs in B cells. Following the traditional lecture, this hands-on activity uses pipe cleaners of various colors representing variable, joining, and diversity gene ...

Learning the statistics and landscape of somatic mutation-induced insertions and deletions in antibodies.

PLoS Computational Biology, 2022
Affinity maturation is crucial for improving the binding affinity of antibodies to antigens. This process is mainly driven by point substitutions caused by somatic hypermutations of the immunoglobulin gene.

Mu heavy chain disease with MYD88 L265P mutation: an unusual manifestation of lymphoplasmacytic lymphoma

Diagnostic Pathology, 2022
Background Mu heavy chain disease is a rare lymphoid neoplasm characterized by vacuolated bone marrow plasma cells and secretion of defective mu immunoglobulin heavy chains. The biological basis of mu heavy chain disease is poorly understood.

Characterization of immunoglobulin heavy chain knockout rats [PDF]

European Journal of Immunology, 2010
AbstractThe rat is a species frequently used in immunological studies but, until now, there were no models with introduced gene‐specific mutations. In a recent study, we described for the first time the generation of novel rat lines with targeted mutations using zinc‐finger nucleases.

Expression of combinatorial immunoglobulins in macrophages in the tumor microenvironment. [PDF]

PLoS ONE, 2018
Recent evidence indicates the presence of macrophage subpopulations that express the TCRαβ in chronic inflammatory diseases such as tuberculosis and atherosclerosis and in the tumor microenvironment.

Immunoglobulin Heavy Chain Exclusion in the Shark

PLoS Biology, 2008
The adaptive immune system depends on specific antigen receptors, immunoglobulins (Ig) in B lymphocytes and T cell receptors (TCR) in T lymphocytes. Adaptive responses to immune challenge are based on the expression of a single species of antigen receptor per cell; and in B cells, this is mediated in part by allelic exclusion at the Ig heavy (H) chain ...

Monoclonal gammopathy of renal significance: Spectrum of diseases and approach to a case

Saudi Journal of Kidney Diseases and Transplantation, 2021
The occurrence of kidney diseases associated with a monoclonal gammopathy in the absence of symptomatic multiple myeloma is increasingly recognized. When the kidney is involved, the monoclonal etiology of these diseases results in clinical and laboratory

Comparative Aspects of Immunoglobulin Gene Rearrangement Arrays in Different Species

Frontiers in Immunology, 2022
Studies in humans and mice indicate the critical role of the surrogate light chain in the selection of the productive immunoglobulin repertoire during B cell development.
