Autosomal Dominant Hyper‐IgE Syndrome Patients Retain IL10‐Producing preTh17‐Cells That Are Activated by Opportunistic Pathogens and Support IgE Production

Allergy, EarlyView.
IL‐10 producing CCR6+Th‐cells are central memory T‐cells that express ROR‐γt and differentiate to Th17‐cells via an autocrine loop of STAT3‐activating cytokines (preTh17). STAT3‐deficient AD‐HIES patients lack Th17‐ and Tfh17‐cells but retain preTh17‐ and Th1/17‐cells.

A proposed reverse transcription mechanism for (CAG)n and similar expandable repeats that cause neurological and other diseases

Heliyon, 2020
The mechanism of (CAG)n repeat generation, and related expandable repeat diseases in non-dividing cells, is currently understood in terms of a DNA template-based DNA repair synthesis process involving hairpin stabilized slippage, local error-prone repair

Increased anergic B cells and decreased antibody‐secreting cells during romiplostim treatment in patients with immune thrombocytopenia

British Journal of Haematology, EarlyView.
Summary Patients with immune thrombocytopenia (ITP) exhibit substantial heterogeneity in treatment responses. Approximately 30%–50% of patients maintain remission after discontinuation of thrombopoietin receptor agonists (TPO‐RA), suggesting immunomodulatory effects beyond enhanced thrombopoiesis.

Molecular mechanisms of avian immunoglobulin gene diversification and prospect for industrial applications

Frontiers in Immunology
Poultry immunoglobulin genes undergo diversification through homologous recombination (HR) and somatic hypermutation (SHM). Most animals share a similar system in immunoglobulin diversification, with the rare exception that human and murine ...

Single‐Cell and Spatial Analysis Reveal the Differences Between Left‐Sided and Right‐Sided Colorectal Cancer

Cell Proliferation, EarlyView.
Single‐cell and spatial analysis revealed distinct CRC microenvironments by tumour laterality. Right‐sided tumours showed enhanced germinal centre B cells, CXCL13+ T cells, and organized TLS‐immune crosstalk via CCL19/21‐CCR7, suggesting better immunotherapy response.

The boundaries of the distribution of somatic hypermutation of rearranged immunoglobulin variable genes

Immunology & Cell Biology, 2004
Available evidence about the mechanisms and distribution of somatic hypermutation (SHM) of rearranged immunoglobulin (IgV) genes is reviewed with particular emphasis on the 5′ boundary. In heavy (H) chain genes, the 5′ boundary of SHM is the transcription start site; in contrast to κ light (L) chain genes, it is located in the leader (L) intron.

DNA Lesions and Repair in Immunoglobulin Class Switch Recombination and Somatic Hypermutation [PDF]

Annals of the New York Academy of Sciences, 2005
Abstract: Immunoglobulin (Ig) gene somatic hypermutation (SHM) and class switch DNA recombination (CSR) are critical for the maturation of the antibody response. These processes endow antibodies with increased antigen‐binding affinity and acquisition of new biological effector functions, thereby underlying the generation of memory B cells and plasma ...

To Treat or Not to Treat: Navigating Early‐Stage CLL in the Era of Targeted Therapy

European Journal of Haematology, EarlyView.
ABSTRACT Chronic lymphocytic leukemia (CLL) is most frequently diagnosed at early, asymptomatic stages (Rai 0/Binet A), in which a watch‐and‐wait strategy remains the standard of care, based on historical trials demonstrating no overall survival benefit from early treatment.

Antibody Affinity Maturation in Fishes—Our Current Understanding

Biology, 2015
It has long been believed that fish lack antibody affinity maturation, in part because they were thought to lack germinal centers. Recent research done on sharks and bony fishes indicates that these early vertebrates are able to affinity mature their ...

Extranodal Marginal Zone Lymphoma: Integrating Etiology, Microenvironment, and Genetics Into Clinical Decision‐Making

European Journal of Haematology, EarlyView.
ABSTRACT Extranodal marginal zone lymphoma (EMZL) represents a unique paradigm among indolent B‐cell neoplasms, in which lymphomagenesis is frequently driven by chronic antigenic stimulation within tissue‐specific microenvironments. Persistent infectious or autoimmune triggers promote the development of ectopic lymphoid tissue and sustain B‐cell ...
