Targeting mutagenesis in B cells: Phosphorylation goes beyond AID association
The mutations induced by activation-induced cytidine deaminase (AID) trigger antibody diversification but can cause genome instability. We find that AID phosphorylation is an important determinant of “off-target” mutagenesis and identify a drug that ...

Engineered CBEs based on Macaca fascicularis A3A with improved properties for precise genome editing
Summary: Cytidine deaminase defines the properties of cytosine base editors (CBEs) for C-to-T conversion. Replacing the cytidine deaminase rat APOBEC1 (rA1) in CBEs with a human APOBEC3A (hA3A) improves CBE properties.

Az aberráns hipermutáció okozta genetikai instabilitás szerepe a B-sejtes non-Hodgkin lymphomák kialakulásában és transzformációjában = The role of genetic instability caused by aberrant hypermutation in the development and transformation of B-cell non-Hodgkin lymphomas [PDF]
A kutatás eredményeként bizonyítottuk, hogy a krónikus lymphocytás leukémia (CLL) és a follicularis lymphoma (FL) kifejezett malignitású lymphomába történő transzformációjában, valamint a mediastinalis nagy B-sejtes lymphoma (MLBL) kialakulásában ...

VH replacement in rearranged immunoglobulin genes [PDF]
Examples suggesting that all or part of the V<sub>H</sub> segment of a rearranged V<sub>H</sub>DJ<sub>H</sub> may be replaced by all or part of another V<sub>H</sub> have been appearing since the 1980s ...

Maize haplotype with a
Background Genetic maps are based on recombination of orthologous gene sequences between different strains of the same species. Therefore, it was unexpected to find extensive non-collinearity of genes between different inbred strains of maize ...

Naturally occurring mutation affecting the MyD88-binding site of TNFRSF13B impairs triggering of class switch recombination [PDF]
Mutations in the transmembrane activator and calcium-modulating cyclophilin ligand interactor (TACI) were previously found to be associated with hypogammaglobulinemia in humans.

APOBEC3G encapsidation into HIV-1 virions: which RNA is it?
APOBEC3G is a cytidine deaminase with potent antiviral activity. The protein deaminates single-stranded DNA but is known to bind cellular and viral RNAs.

Elevated numbers of PD-L1 expressing B cells are associated with the development of AIDS-NHL. [PDF]
The risk for non-Hodgkin lymphoma (NHL) is markedly increased in persons living with human immunodeficiency virus (HIV) infection, and remains elevated in those on anti-retroviral therapy (cART).
