Small particles of Echinococcus granulosus (spegs) and Echinococcus multilocularis (spems) promote follicular T helper cell expansion and are associated with IgE and IgG4 class switching in human lymph nodes

open access: yesParasites & Vectors
Background Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are zoonotic diseases caused by the larval stages of Echinococcus granulosus and E. multilocularis.

B cell intrinsic and extrinsic factors impacting memory recall responses to SRBC challenge

open access: yesFrontiers in Immunology, 2022
MBCs (MBCs) generated in T-dependent immune responses can persist for a lifetime and rapidly react upon secondary antigen exposure to differentiate into plasma cells (PCs) and/or to improve the affinity of their BCR through new rounds of hypermutation in

Secretory IgA (SIgA): designed for antimicrobial defence

open access: yesFrontiers in Immunology, 2013
Prevention of infections by vaccination remains a compelling goal to improve public health. Mucosal vaccines would make immunization procedures easier, be better suited for mass administration, and most efficiently induce immune exclusion -- a term ...

NGFR regulates stromal cell activation in germinal centers

open access: yesCell Reports
Summary: Nerve growth factor receptor (NGFR) is expressed by follicular dendritic cells (FDCs). However, the role of NGFR in the humoral response is not well defined.

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)

Morphological changes in lymph nodes and spleen upon EAE induction in C57BL/6 mic [PDF]

open access: yesArchives of Biological Sciences, 2013
Myelin oligodendrocyte glycoprotein (MOG) is a protein widely used in the induction of experimental autoimmune encephalomyelitis (EAE) for studying human multiple sclerosis (MS).

Capturing change in clonal composition amongst single mouse germinal centers

open access: yeseLife, 2018
Understanding cellular processes occurring in vivo on time scales of days to weeks requires repeatedly interrogating the same tissue without perturbing homeostasis.

IL-12 Blocks Tfh Cell Differentiation during Salmonella Infection, thereby Contributing to Germinal Center Suppression

open access: yesCell Reports, 2019
Summary: Germinal centers (GC) are crucial for the formation of long-lived humoral immunity. Many pathogens suppress GC, including Salmonella enterica serovar Typhimurium (STm), but the mechanisms driving suppression remain unknown.

DNA immunisation. New histochemical and morphometric data

open access: yesEuropean Journal of Histochemistry, 2010
Splenic germinal center reactions were measured during primary response to a plasmidic DNA intramuscular injection. Cardiotoxin-pretreated Balb/c mice were immunized with DNA plasmids encoding or not the SAG1 protein, a membrane antigen of Toxoplasma ...

Inference of germinal center evolutionary dynamics via simulation-based deep learning

open access: yeseLife
B cells and the antibodies they produce are vital to health and survival, motivating research on the details of the mutational and evolutionary processes in the germinal centers (GCs) from which mature B cells arise.
