Diversity of immunoglobulin light chain genes in non-teleost ray-finned fish uncovers IgL subdivision into five ancient isotypes [PDF]

, 2018
The aim of this study was to fill important gaps in the evolutionary history of immunoglobulins by examining the structure and diversity of IgL genes in non-teleost ray-finned fish.

Unrearranged immunoglobulin variable region genes have a functional promoter

Nucleic Acids Research, 1982
We have tested whether immunoglobulin light chain variable region genes are capable of directing initiation of transcription without undergoing the DNA rearrangement which creates a complete immunoglobulin gene. Two human Vk genes specifically initiated transcription in vitro at a site which is approximately 30 bases downstream of a TATA box and 20 ...

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

Intrathecal B-cell activation in LGI1 antibody encephalitis. [PDF]

, 2020
ObjectiveTo study intrathecal B-cell activity in leucine-rich, glioma-inactivated 1 (LGI1) antibody encephalitis. In patients with LGI1 antibodies, the lack of CSF lymphocytosis or oligoclonal bands and serum-predominant LGI1 antibodies suggests a ...

Evidence for a quadruplex structure in the polymorphic hs1.2 enhancer of the immunoglobulin heavy chain 3’ regulatory regions and its conservation in mammals [PDF]

, 2016
Regulatory regions in the genome can act through a variety of mechanisms that range from the occurrence of histone modifications to the presence of protein-binding loci for self-annealing sequences.

Digital twins to accelerate target identification and drug development for immune‐mediated disorders

FEBS Open Bio, EarlyView.
Digital twins integrate patient‐derived molecular and clinical data into personalised computational models that simulate disease mechanisms. They enable rapid identification and validation of therapeutic targets, prediction of drug responses, and prioritisation of candidate interventions.

Immunoglobulin secretion influences the composition of chicken caecal microbiota

Scientific Reports
The chicken caecum is colonised by hundreds of different bacterial species. Which of these are targeted by immunoglobulins and how immunoglobulin expression shapes chicken caecal microbiota has been addressed in this study. Using cell sorting followed by

Amplification and analysis of cDNA generated from a single cell by 5′-RACE: application to isolation of antibody heavy and light chain variable gene sequences from single B cells

BioTechniques, 2006
The technique of 5′-rapid amplification of cDNA ends (5′-RACE) is widely used to amplify unknown sequences at the 5′ end of a messenger RNA (mRNA). However, conventional 5′-RACE is inappropriate for producing cDNAs from a single cell due to the small ...

Individual B cells transcribe multiple rearranged immunoglobulin light chains in teleost fish

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 ...
