Alterations in Peripheral Blood B Cell Subsets and Dynamics of B Cell Responses during Human Schistosomiasis

Antibody responses are thought to play an important role in control of Schistosoma infections, yet little is known about the phenotype and function of B cells in human schistosomiasis. We set out to characterize B cell subsets and B cell responses to B cell receptor and Toll-like receptor 9 stimulation in Gabonese schoolchildren with Schistosoma haematobium infection. Frequencies of memory B ce...

B Cell Subsets in Atherosclerosis

Atherosclerosis, the underlying cause of heart attacks and strokes, is a chronic inflammatory disease of the artery wall. Immune cells, including lymphocytes modulate atherosclerotic lesion development through interconnected mechanisms. Elegant studies over the past decades have begun to unravel a role for B cells in atherosclerosis. Recent findings provide evidence that B cell effects on ather...

Sex Hormones and Peripheral White Blood Cell Subsets in Systemic Lupus Erythematosus Patients

Background: Systemic Lupus Eyrythematosus (SLE) is an autoimmune disease charac-terized by antibodies to nuclear antigens, particularly anti-dsDNA. Imbalance between production and destruction of immune cells causes cytopenia. Sex hormones have im-munomodulatory effects; estrogen increases the production of autoantibodies in SLE prone NZB/NZW mice. Objective: To investigate the relationship bet...

Cell Maturation Multiple Selection Points During Peripheral B Immature Splenic B Cell Subsets Reveals Resolution of Three Nonproliferative

RAG1 and RAG2 expression by B cell subsets from human tonsil and peripheral blood.

It has been suggested that B cells acquire the capacity for secondary V(D)J recombination during germinal center (GC) reactions. The nature of these B cells remains controversial. Subsets of tonsil and blood B cells and also individual B cells were examined for the expression of recombination-activating gene (RAG) mRNA. Semiquantitative analysis indicated that RAG1 mRNA was present in all tonsi...
