B cell MHC haplotype affects follicular inclusion, germinal center participation and plasma cell differentiation in a mouse model of lupus

open access: yesFrontiers in Immunology, 2023
IntroductionMHC class II molecules are essential for appropriate immune responses against pathogens but are also implicated in pathological responses in autoimmune diseases and transplant rejection.

Generation of High Quality Memory B Cells

open access: yesFrontiers in Immunology, 2022
Protection against pathogen re-infection is mediated, in large part, by two humoral cellular compartments, namely, long-lived plasma cells and memory B cells.

Antigen presentation by B cells enables epitope spreading across an MHC barrier

open access: yesNature Communications, 2023
Circumstantial evidence suggests that B cells may instruct T cells to break tolerance. Here, to test this hypothesis, we used a murine model in which a single B cell clone precipitates an autoreactive response resembling systemic lupus erythematosus (SLE)

Dynamic 3D Locus Organization and Its Drivers Underpin Immunoglobulin Recombination

open access: yesFrontiers in Immunology, 2021
A functional adaptive immune system must generate enormously diverse antigen receptor (AgR) repertoires from a limited number of AgR genes, using a common mechanism, V(D)J recombination.

Adenomatous Polyposis Coli Defines Treg Differentiation and Anti-inflammatory Function through Microtubule-Mediated NFAT Localization

open access: yesCell Reports, 2017
Adenomatous polyposis coli (APC) is a polarity regulator and tumor suppressor associated with familial adenomatous polyposis and colorectal cancer development.

Heterochronic faecal transplantation boosts gut germinal centres in aged mice

open access: yesNature Communications, 2019
Microbiota impacts all major aspects of physiology, but little is known about its effects on age-related changes in immune responses. Here the authors show that gut microbiota transfer between adult and old mice increases local but not systemic germinal ...

Rejuvenating conventional dendritic cells and T follicular helper cell formation after vaccination

open access: yeseLife, 2020
Germinal centres (GCs) are T follicular helper cell (Tfh)-dependent structures that form in response to vaccination, producing long-lived antibody secreting plasma cells and memory B cells that protect against subsequent infection. With advancing age the

Variant surface glycoprotein density defines an immune evasion threshold for African trypanosomes undergoing antigenic variation

open access: yesNature Communications, 2017
Trypanosoma brucei evades the host immune system through replacement of a variant surface glycoprotein (VSG) coat. Here, the authors show that VSG replacement takes several days to complete, and the parasite is vulnerable to the host immune system for a ...

CCCTC-Binding Factor Locks Premature IgH Germline Transcription and Restrains Class Switch Recombination

open access: yesFrontiers in Immunology, 2017
In response to antigenic stimulation B cells undergo class switch recombination (CSR) at the immunoglobulin heavy chain (IgH) to replace the primary IgM/IgD isotypes by IgG, IgE, or IgA.

Structure of mammalian Mediator complex reveals Tail module architecture and interaction with a conserved core

open access: yesNature Communications, 2021
The Mediator complex regulates RNA polymerase II transcription in all eukaryotes. The mammalian Mediator cryo-EM structure reveals the architecture of previously unresolved Tail module and suggests its regulatory role in the complex conformation and ...
