Clonal diversity in the B cell repertoire of patients with X-linked agammaglobulinemia

Ig protein and mRNA expression was examined in a collection of 18 monoclonal EBV-transformed B cell lines derived from five patients with X-linked agammaglobulinemia (XLA). A diversity of H and L chain isotypes were synthesized by these lines: the majority (12 lines) expressed mu kappa chains, while mu lambda (two lines), gamma kappa (one), gamma lambda (one), delta lambda (one), and alpha kapp...

B cells in patients with X-linked agammaglobulinemia.

X-linked agammaglobulinemia (XLA) has been described as a disorder in which pre-B cells fail to differentiate into B cells. However, a small number of B cells have been seen occasionally in patients with this disorder. Because the phenotype of these cells might be helpful in defining the site of the defect in XLA, immunofluorescent staining techniques were used to characterize the B cells that ...

neutropenia associated with x-linked agammaglobulinemia

x-linked agammaglobulinemia (xla) is a hereditary immunodeficiency, characterized by an early onset of recurrent bacterial infections, hypogammaglobulinemia and markedly reduced b lymphocytes number. in order to determine the association of neutropenia among iranian patients with xla, hospital records of 30 patients with confirmed xla in children medical center hospital, were reviewed. eight ou...

Diversity and clonal selection in the human T-cell repertoire.

T-cell receptor (TCR) diversity, a prerequisite for immune system recognition of the universe of foreign antigens, is generated in the first two decades of life in the thymus and then persists to an unknown extent through life via homeostatic proliferation of naïve T cells. We have used next-generation sequencing and nonparametric statistical analysis to estimate a lower bound for the total num...

Clonal expansion is a characteristic feature of the B-cell repertoire of patients with rheumatoid arthritis

The present study was designed to analyze the level of B-cell clonal diversity in patients with rheumatoid arthritis by using HCDR3 (third complementarity determining region of the rearranged heavy chain variable region gene) length as a marker. A modified immunoglobulin VH gene fingerprinting method using either genomic DNA or complementary (c)DNA derived from B cells of the peripheral blood, ...
