Autoreactive B cells are actively tolerized to more abundant self-antigens by a series of checkpoints involving receptor editing, deletion, anergy and competition for growth factors. In contrast, B cells reactive against rare, sequestered or tissue specific self-antigens remain functionally naïve.

The B cell receptor, but not the pre-B cell receptor, mediates arrest of B cell differentiation [PDF]
B cell development in organ cultures of fetal liver from mice at day 14 of gestation resembles in kinetics and cell numbers generated the one observed in vivo. This development in vitro can be blocked by an IL-7 receptor-specific monoclonal antibody. Monoclonal antibodies specific for the pre-B cell receptor, i. e. for VpreB, lambda5, or muH chains, do

B cell memory: building two walls of protection against pathogens
Surviving a single infection often results in lifelong immunity to the infecting pathogen. Such protection is mediated, in large part, by two main B cell memory ‘walls’ — namely, long-lived plasma cells and memory B cells.

Association of B-cell Lymphoma Protein-2 and Caspase-3 Expression in Ovarian Cancer [PDF]
Ovarian cancer remains a major problem of women's health in the world, including Indonesia, and is associated with high rates of incidence and mortality. There are many efforts in early diagnosis on ovarian cancer, but until now there have not been found

Conjugate Haemophilus influenzae type b vaccines for sickle cell disease. [PDF]
BACKGROUND: People affected with sickle cell disease are at high risk of infection from Haemophilus influenzae type b. Before the implementation of Haemophilus influenzae type b conjugate vaccination in high-income countries, this was responsible for a ...

occumb: An R package for site occupancy modeling of eDNA metabarcoding data
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

BACKGROUND: B-cells express a variety of clusters of differentiation markers during development. These markers determine the basic function of the immune phenotype specific to B-cells.

Activation‐induced deaminase (AID) initiates secondary antibody diversification in germinal center B cells, giving rise to higher affinity antibodies through somatic hypermutation (SHM) or to isotype‐switched antibodies through class switch recombination

Molecular and functional properties of human Plasmodium falciparum CSP C‐terminus antibodies
Human monoclonal antibodies (mAbs) against the central repeat and junction domain of Plasmodium falciparum circumsporozoite protein (PfCSP) have been studied extensively to guide malaria vaccine design compared to antibodies against the PfCSP C terminus.

Primary mediastinal lymphoma: diagnosis and treatment options. [PDF]
Primary mediastinal large B-cell lymphoma (PMBCL) is a unique B-cell lymphoma variant that arises from a putative thymic medulla B cell. It constitutes 2-4% of non-Hodgkin lymphomas and occurs most frequently in young females. PMBCL is characterized by a
