The significance of peripheral blood natural killer cell surface CD107a, NKG2D and serum sMICA in patients with extranodal NK/T cell lymphoma, nasal type / 中华内科杂志

ABSTRACT

The expression of CD107a,NKG2D on the surface of natural killer (NK) cells and serum soluble major histocompatibility complex class Ⅰ chain-related A (sMICA) level in patients with extranodal NK/T cell lymphoma,nasal type (ENKL) were detected.We found that CD107a expression was reduced on the surface of NK cells,suggesting impaired NK cell activity in ENKL patients,which may result from decreased NKG2D expression.
