TCR Transgenic Mouse Model, grb, dependent on HLA B27 for response

Strain: GRb-TCR-TG, Background: BALB/c

To study the potential roles and behaviour of an HLA B27-restricted T cell in vivo, a model system in which variable portions of a TCR (denoted GRb) originally derived from an HLA B27-positive volunteer are expressed as a transgene in an HLA B2705, human _2-microglobulin (h_2m)2 transgenic (TG) mouse using a mouse genomic cassette vector. The receptor is expressed and produces fully functional T cells in the context of HLA B27. CD4+ T cells expressing the TCR receptor can function as HLA B27-restricted T cells and are capable of differentiation to secrete cytokines indicative of either Th1 or Th2 subsets of T cells.

The University’s policy is to minimise the use of animals in research, consistent with the need to make significant advances on important problems of human health. Where animal research is necessary, the University will provide housing and care that exceeds, wherever possible, legal requirements. The University will also continually pursue techniques that reduce the number of animals involved in research. For further information about animal research at Oxford, click here.
