title: [Analysis of T lymphocytic clones in diseases by spectrotyping of T cell beta variable region - review].
abstract: T cells recognize antigens through TCRs (T cell receptor). T cell clones can be sorted into 24 gene subfamilies based on the usage of the segments of TCR BV in gene rearrangement. Application of the various segments of TCR BV may establish TCR BV spectrotyping that can be used to analyze and recognize the different functional T cell clones, and understand the function and proliferation of various T cell clones in malignancy and autoimmune disease. In vitro expansion of a great deal of the specific antitumor T cells and transfusing them to patients will be able to develop a new method for tumor immunotherapy. Through analyze the character of the TCR BV gene, McAb against TCR or DNA vaccine to inhibit the growth of T cell clones associated-autoimmune disease and tumors might be developed. The McAb and vaccine may be used to cure these diseases. The commo T cells can also be modifed to specific antitumor T cells by method of TCR gene transfer. In this review, the characteristics of TCR, analysis method for gene spectrotyping of TCR BV, segments of TCR BV and autoimmue distase, T cell clones in hematologic maligrancies, recognition of T cell oligoclone expansion of T cells, and application of TCR BV gene spectrotyping in bone marrow transplantation were discussed and summarised.
