  • 4 In the World Health Organization (WHO) classification of 2001, T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is defined by the presence of a limited number of scattered large B cells in a background rich in T cells, with or without histiocytes. (haematologica.org)

  • The term "oncotarget" encompasses all molecules, pathways, cellular functions, cell types, and even tissues that can be viewed as targets relevant to cancer as well as other diseases. (oncotarget.com)
  • In addition these CD86 findings also showed that PDGFRβ+ perivascular cells from non-lymphoid organs have the capacity to differentiate into FDCs and in vivo thus suggesting that this cell population may be the source of AS 602801 (Bentamapimod) FDC in tertiary lymphoid organ formation (Krautler et al.

  • These isotype-switched CLL B cells expressed surface HLA-DR, CD19, CD23, and CD5, and displayed no alterations of the bcl-1 and bcl-2 oncogenes and the p53 tumor-suppressor gene. (omicsdi.org)
  • The cDNA VH-D-JH gene sequence was joined with that of the C alpha gene in the B cells of the three IgA CLLs, and with that of the C gamma gene in the IgG CLL B cells. (omicsdi.org)
  • In all five CLLs, the pattern of C mu DNA probe hybridization to the digested genomic DNAs was consistent with deletion of the C mu exon from the rearranged Ig gene locus, suggesting that these CLL B cells had undergone DNA switch recombination. (omicsdi.org)
  • These findings suggest that IgA- and/or IgG-expressing CLLs represent, in their VH gene structure, transformants of B cells at different stages of ontogeny. (omicsdi.org)
  • They also suggest that Ag may play a role in the clonal selection of some of these isotype-switched leukemic cells, but bcl-1 and bcl-2 oncogene rearrangements and p53 tumor suppressor gene mutation are not associated with the pathogenesis of isotype-switched CLLs. (omicsdi.org)

  • The decision to return to the DZ and undergo clonal expansion is controlled by T helper cells in the GC LZ, which discern between LZ B cells based on the amount of antigen captured and presented. (ox.ac.uk)
  • The molecular data indicate that approximately 50% of B-CLL patients have amplifications of IgM+ B cells that undergo an isotype class switch. (omicsdi.org)
  • The cellular data indicate that B cells with lesser amounts of surface membrane IgD and higher IgM/IgD ratios are more likely to undergo this switching process. (omicsdi.org)
