We investigated the expression of natural killer cell receptors (NKRs) for HLA-C on peripheral blood mononuclear cells (PBMCs) in 23 allogeneic bone marrow transplantation (allo-BMT) patients to analyse the role of NKRs in alloresponse concerning graft-versus-host disease (GVHD). CD158a expression was low and there was little change in the expression after allo-
BMT
. Also, there was no difference in the proportion of CD158a+/CD3- after allo-
BMT
. In contrast, the proportion of CD158b+/CD3- cells, mainly NK cells, increased in the early stage (< 2 months) after allo-
BMT
and then gradually decreased (3.3 +/- 2.6% before
BMT
vs. 15.4 +/- 8. 6% in the early stage after
BMT
, 8.5 +/- 4.9% during the period 3-6 months after
BMT
and 7.0 +/- 3.0% > 6 months after
BMT
; P < 0.05). However,
CD158b
expression on CD3+ T cells increased 3 months after allo-
BMT
(1.1 +/- 1.1% before
BMT
vs. 5.1 +/- 7.7% during the period 3-6 months after
BMT
and 3.0 +/- 2.4% > 6 months after
BMT
, P < 0. 05). The highest percentages of CD158 expression in patients without chronic GVHD (cGVHD) and those with cGVHD were compared. The percentage of CD158b+/CD3+ cells and also that of CD158b+/CD8+ cells were significantly increased in patients with cGVHD compared with those in patients without cGVHD (2.6 +/- 2.0% vs. 8.0 +/- 11.2% and 2.3 +/- 1.5% vs. 8.3 +/- 11.7% respectively; P < 0.05). The exact clinical relevance of these
CD158b
-expressing cells is not clear. However, there is an interesting possibility that
CD158b
-expressing cells play some role in the regulation of GVHD after allo-
BMT
.
