Single‐Cell Level Characterization of B Cell Depletion and Repopulation Following Rituximab in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Rituximab, a CD20+ B cell depletion therapy, is frequently used to treat systemic lupus erythematosus (SLE). However, variability in patient response highlights the need for a deeper understanding of the underlying immune cell dynamics of B cell depletion and repopulation.

The Role of IgM Anti‐acetylated Protein Antibodies and B Cells in the Origin of Antimodified Protein Autoimmunity in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated protein antibodies (ACPA), anti‐carbamylated protein antibodies (anti‐CarP), and anti‐acetylated protein antibodies (AAPA). In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role ...

Immunoglobulin gene loci structure and diversity of raccoon dog (Nyctereutes procyonoides)

BMC Genomics
In this study, we analyzed the loci structure of raccoon dog genes using a comparative genomics approach. We investigated the mechanism of expression diversity and its preference using the Next-generation sequencing.

Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, EarlyView.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

Accurate immune repertoire sequencing reveals malaria infection driven antibody lineage diversification in young children

Nature Communications, 2017
Somatic hypermutation of antibodies can occur in infants but are difficult to track. Here the authors present a new method called MIDCIRS for deep quantitative repertoire sequencing with few cells, and show infants as young as 3 months can expand ...

Adaptive Immunity in Marsupials

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

IgG1 memory B cells keep the memory of IgE responses

Nature Communications, 2017
IgE is an important mediator of protective immunity as well as allergic reaction, but how high affinity IgE antibodies are produced in memory responses is not clear.

Mutating for Good: DNA Damage Responses During Somatic Hypermutation

Frontiers in Immunology, 2019
Somatic hypermutation (SHM) of immunoglobulin (Ig) genes plays a key role in antibody mediated immunity. SHM in B cells provides the molecular basis for affinity maturation of antibodies.

DNA repair in antibody somatic hypermutation [PDF]

Trends in Immunology, 2006
Somatic hypermutation (SHM) underlies the generation of a diverse repertoire of high-affinity antibodies. It is effected by a two-step process: (i) DNA lesions initiated by activation-induced cytidine deaminase (AID), and (ii) lesion repair by the combined intervention of DNA replication and repair factors that include mismatch repair (MMR) proteins ...
