Study uncovers how B cells react to skin cancer

by King’s College London Spatial transcriptomic coupled with high throughput intratumoral antibody repertoire analyses suggest an active but aberrant B cell response. a Representative image of spatial transcriptomic deconvolution of B cells, T cells and B cell germinal center (GC) signatures. Top panels, signature score per spot; bottom panels, binarized values using 50% (B cells and T cells)...

Atherosclerosis: How the body controls the activity of B cells

by Ludwig Maximilian University of Munich Regulation and function of GPR55 signaling in atherosclerosis. a–d, Plasma, spleens and aortic roots were collected from Apoe−/− mice at baseline or after 4 weeks and 16 weeks of WD to determine LPI plasma concentrations (n = 7–8; *P = 0.05 and ***P = 0.0042) (a) or relative splenic mRNA expression of the gene encoding the LPI-synthesizing enzyme...

Antibody-producing b cells may be ‘predestined’ for their fates

by Weill Cornell Medical College Credit: Blausen Medical, CC BY-SA 4.0 The master regulator behind the development of antibody-producing cells has been identified in a study by investigators at Weill Cornell Medicine. The findings provide new insight into the inner workings of the immune system and may help understand how tissues develop and how certain...

Age-Associated B Cells in Immunosenescence

The immune system becomes disordered and dysfunctional with age in numerous different ways. The B cell component accumulates inflammatory and problematic cells that are known as age-associated B cells. Here, researchers show that these errant B cells produce antibodies that provoke autoimmunity. B cell aging is a problem with a solution demonstrated in animal models: just destroy all B cells. Mammals can get by without B...
