As initially proposed by Billingham in 1966,14 three conditions are required for the development of GVHD: (1) the graft must contain immunologically competent cells; (2) the host itself must be incapable of mounting an effective immunologic reaction against the graft; and (3) the host must possess important transplant alloantigens that are lacking in the donor graft so that the host appears foreign to the graft.
from the University of New SouthWales (Australia) showed that Th1 and Th2 responses promoted the development of two different pathways of alloantigen specific Tregs in vivo, depending on the cytokine milieu.

(3) The very rare allele 4 (gene frequency < 0.01) uniquely expresses 2531T, which defines the [Sit.sup.a] alloantigen. Within the coding sequence, 2 single-point missense dimorphisms have been described: A1648G (Lys505Glu) and C2531T (Thr799Met) are responsible for the formation of the [Br.sup.a]/[Br.sup.b] (HPA-5) and [Sit.sup.a] alloantigens (HPA-12bw), respectively.
NK1.1 is a marker of natural killer (NK) cells and an alloantigen whose expression is limited to NK cells in several mouse strains [58, 59].

The orchestrated response of innate and adaptive immune cells against the alloantigen is highly dependent on directed migration and homing of immune cells to the lymphoid tissues and site of inflammation [6].
