Confined B‐Cell Reconstruction and High T‐Cell Clonality Define Clinical Response to Cladribine Treatment

Annals of Neurology, EarlyView.
Cladribine tablets are approved for relapsing multiple sclerosis, mediating their clinical effect by moderately depleting lymphocytes. In a prospective, monocentric study including 22 patients completing 2 annual cycles of cladribine, B‐ and T‐cell receptor repertoires and relapse activity were assessed at baseline and after 24 months. T‐cell clonality

AID/APOBEC–dependent somatic hypermutation and DNA rearrangements of immunoglobulin and non-immunoglobulin genes [PDF]

Annals of Mechnikov's Institute, 2019
Editing Ig genes by activation induced deaminase (AID) initiates the antibody diversification process in B lymphocytes.In mammalian B cells, this process includes somatic hypermutation (SHM) and class switch recombination (CSR).The activity of AID is ...

Directed molecular evolution by somatic hypermutation [PDF]

Protein Engineering Design and Selection, 2004
After rearrangement of immunoglobulin gene segments, the immune system evolves the antibody repertoire by mutating the immunoglobulin variable region at a high rate. While this somatic hypermutation was thought to occur only at the variable region, recent studies suggest that hypermutation can occur at locations throughout the genome.

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Clonal redemption of autoantibodies by somatic hypermutation away from self-reactivity during human immunization

Journal of Experimental Medicine, 2016
Goodnow et al. show that in vaccinated humans, anergic autoreactive B cells can hypermutate the B cell receptor during the immune response and remove binding to self while enhancing binding to the vaccine.

Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side

Allergy, EarlyView.
ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.

Original Antigenic Sin: the Downside of Immunological Memory and Implications for COVID-19

mSphere, 2021
The concept of original antigenic sin (OAS) was put forth many years ago to explain how humoral memory responses generated against one set of antigens can affect the nature of antibody responses elicited to challenge infections or vaccinations containing

DNA polymerase ι functions in the generation of tandem mutations during somatic hypermutation of antibody genes

Journal of Experimental Medicine, 2016
Gearhart and collaborators address the long-standing question of the roles of error-prone DNA polymerases in somatic hypermutation of antibody genes.

Dynamics of circulating tumour DNA in relapsed/refractory diffuse large B‐cell lymphoma patients

British Journal of Haematology, EarlyView.
Summary The response to salvage chemotherapy in relapsed/refractory (R/R) diffuse large B‐cell lymphoma (DLBCL) is poor, and data on circulating tumour deoxyribonucleic acid (ctDNA) in this setting are limited. We evaluated ctDNA dynamics in 29 patients with relapsed or refractory DLBCL who received platinum‐based salvage chemotherapy at the University
