Current opinion in immunology, 2001•ElsevierThe direct pathway of allorecognition is involved in acute allograft rejection and is
characterised by TCR-mediated recognition of the MHC framework; this is thought to occur
in a peptide-dependent but not peptide-specific manner. In contrast, the indirect pathway is
restricted to the recipient's own MHC molecules and prevails in chronic rejection. In this
pathway, the peptide has a major influence on the TCR recognition and selects alloreactive
T cells with altered TCR Vβ usage. However, qualitative analysis of Vβ usage alone might …

In contrast, the indirect pathway is restricted to the recipient's own MHC molecules and prevails in chronic rejection. In this pathway, the peptide has a major influence on the TCR recognition and selects alloreactive T cells with altered TCR Vβ usage. However, qualitative analysis of Vβ usage alone might limit our understanding of alloreactivity. The advantages of a combined quantitative assessment of Vβ mRNA usage are discussed.
