IgM-producing tumors in the BALB/c mouse: a model for B-cell maturation [PDF]

, 1974
Five adjuvant induced BALB/c tumors producing IgM—McPc 1748, W 3469, TEPC 183, McPc 774, and Y 5781—were characterized morphologically by electron microscopy, analysis of the distribution of surface-bound and intracytoplasmic IgM using immunofluorescence,

Human IgM+CD27+ B Cells: Memory B Cells or “Memory” B Cells? [PDF]

The Journal of Immunology, 2007
Abstract Memory B cells are generated in germinal centers (GC) and contribute to serological immunity by rapidly differentiating into plasma cells. Human memory B cells can be identified by the expression of CD27. These cells exhibit more rapid responses than naive (CD27−) B cells following stimulation in vitro, consistent with the ...

Ten-year experience with rituximab for induction and maintenance therapy in patients with ANCA-associated systemic vasculitis

Современная ревматология, 2020
Rituximab (RTM), a monoclonal antibody against CD20+ receptors on the membrane of B-cells, is becoming increasingly important for the induction and maintenance treatment of antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (ANCA ...

Stromal Cells Attract B‐Cell Progenitors to Promote B‐Cell–B‐Cell Contact and Maturation [PDF]

Scandinavian Journal of Immunology, 2005
AbstractThe in vitro differentiation of B‐lineage progenitors into Ig‐secreting mature B cells has classically required a co‐culture system containing lipopolysaccharide (LPS) and stromal cells. We have previously showed that B‐lineage progenitors cultured in round‐bottomed wells can mature and secrete immunoglobulin M (IgM) on par with cultures ...

Conditional immortalization of human B cells by CD40 ligation [PDF]

, 2008
It is generally assumed that human differentiated cells have a limited life-span and proliferation capacity in vivo, and that genetic modifications are a prerequisite for their immortalization in vitro.

Th17 effector cells support B bell responses outside of germinal centres [PDF]

, 2012
Th17 cells are pro-inflammatory CD4+T cells, which are important in immune responses against fungal pathogens and extracellular bacteria and have also been implicated in various autoimmune syndromes.

Prevention of arthritis by interleukin 10-producing B cells [PDF]

, 2003
In this study we have shown that activation of arthritogenic splenocytes with antigen and agonistic anti-CD40 gives raise to a B cell population that produce high levels of interleukin (IL)-10 and low levels of interferon (IFN)-{gamma}. Transfer of these

Inhibition of T cell/B cell interaction by B-CLL cells [PDF]

Leukemia, 1999
The course of disease in patients suffering from chronic lymphocytic leukemia (CLL) is determined by a profound dysregulation of the immune system. The resulting immune suppression is the main cause of death in those patients. In the present study we addressed the question of whether leukemic B cells (B-CLL) are able to suppress regular T cell/B cell ...

Tolerance without clonal expansion: self-antigen-expressing B cells program self-reactive T cells for future deletion [PDF]

, 2008
B cells have been shown in various animal models to induce immunological tolerance leading to reduced immune responses and protection from autoimmunity.
