A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Immunoglobulin variable-region (V) genes, it is now recognized, do not encode specific receptors for T lymphocytes. Classical observations on T-cell expression of immunoglobulin idiotypes had remained unexplained until recent experiments showed that immunoglobulin idiotypes expressed by T lymphocytes in normal mice are absent in cells of the same specificity isolated from donors whose B-cell system has been suppressed by administration of anti-mu antibodies from birth. This observation provided evidence for the ‘learning’ of T-cell idiotypes from the B-cell/antibody system and, therefore, for the importance of idiotypic network interactions in the selection of available lymphocyte repertoires before antigenic challenge. Previously described influences of B cells and/or antibodies on the T-helper (Th) cell compartment would appear to operate at the level of clonal repertoires by complementarities with defined immunoglobulin idiotypes. Other authors, however, had previously shown the striking stability of T-cell idiotype expression in chimaeric animals reconstituted with T and B cells originating from donors showing differential idiotype expression. We have now investigated this apparent discrepancy and present here results demonstrating that immunoglobulin-dependent selection of T-cell (idiotypic) repertoires only operates for the first 3 weeks of life.
