Atypical memory B cells (MBCs) appear to differentiate from classical MBCs during chronic exposure to the malaria parasite Plasmodium falciparum, and may interfere with the acquisition of immunity to the disease.

Androgen receptor activation modifies B cell frequencies and functionality, accompanied by weight gain in female mice exposed to human PCOS IgG, highlighting the unrecognized involvement of B cells in PCOS autoimmune comorbidities despite their absence not preventing PCOS phenotype development.

B-cell integrin co-stimulation promotes the formation of an actomyosin network that drives integrin-dependent immune synapse formation and B-cell activation.

The RNA-binding protein polypyrimidine tract-binding protein 1 (PTBP1) is essential for B cell development at the pro-B cell stage where it suppresses S-phase entry and promotes progression through mitosis.

Antibody paratopes can be added to the human repertoire by CRISPR-Cas9 editing of B lymphocytes using a strategy that allows for hypermutation and class switching of resulting B cell receptors.

Targeting nuclear self-antigens to germinal center B cells induces rapid accumulation of follicular regulatory T cells with immunosuppressive phenotype and leads to inhibition of germinal center response with predominant suppression of the nuclear protein-acquiring germinal center B cells.

IFNγ increases the responsiveness of human B cells to IL-2, TLR7/8 and IL-21 signals and therefore enhances antibody production in inflammatory settings associated with autoimmune or chronic disease.

The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.

Single-cell RNA sequencing provides a detailed understanding of the cues controlling in vitro differentiation of human B cells into antibody-secreting cells (ASCs), uncovering a novel pre-ASC population present ex vivo in lymphoid tissues that progress through a germinal center-like state.

Two modes of actin polymerization, branched and linear, cooperate in B cells to extract antigens from surfaces of presenting cells.
