Streptococcus suis serotype 2 is an important encapsulated bacterial swine pathogen and zoonotic agent for which no effective vaccine exists. The interaction with B cells and the humoral response against S. suis are poorly understood despite their li

Summary: Elimination of self-reactive T cells in the thymus is critical to establish T-cell tolerance. A growing body of evidence suggests a role for thymic B cells in the elimination of self-reactive thymocytes. To specifically address the role of t

Protective antibody responses depend critically on proper B cell development and differentiation at multiple stages. Here the authors show that a protein arginine methyltransferase, Prmt5 uses multiples pathways to prevent death of immature B cells,

The enzyme Activation induced deaminase (AID) underpins antibody affinity maturation and isotype switching through its mutagenic activity of deaminating deoxycytidine to deoxyuridine in DNA. Subsequent processing of the deoxyuridine initiates the pro

Adenosine-to-inosine conversion at position 34 (A34-to-I) of certain tRNAs is essential for expanding their decoding capacity. This reaction is catalyzed by the adenosine deaminase acting on tRNA (ADAT) complex, which in Eukarya is formed by two subu

SLAM family receptors are involved in humoral immune regulation. In this issue of JEM, Zhong et al. provide evidence that these receptors collectively suppress germinal center reaction but promote production of antigen-specific antibodies.

Verdun and colleagues find that the uracil-DNA glycosylase UNG, which promotes DNA breaks in the immunoglobulin genes during class switch recombination and is required for AID-induced chromosomal translocations, protects telomeres from AID-induced DN

Mechanisms regulating B cell development, activation, education in the germinal center (GC) and differentiation, underpin the humoral immune response. Protein arginine methyltransferase 5 (Prmt5), which catalyzes most symmetric dimethyl arginine prot

Activation induced deaminase (AID) initiates somatic hypermutation and class switch recombination of the Ig genes in antigen-activated B cells, underpinning antibody affinity maturation and isotype switching. AID can also be pathogenic by contributin

Activation-induced deaminase (AID) triggers antibody class switch recombination (CSR) in B cells by initiating DNA double strand breaks that are repaired by nonhomologous end-joining pathways. A role for AID at the repair step is unclear. We show tha
