Expression of natural killer cell markers in XXXX .

@entity1893 @entity706 @entity784 @entity4755
One hundred forty-nine cases of @entity1893 were studied with a panel of monoclonal antibodies, including antibodies to natural killer (NK) cells--anti-NKH1, anti- @entity4755 , and anti-Leu 11b. There were 95 B-cell, 51 T-cell, and three null cell @entity706 . @entity784 (33 per cent) expressed NKH1, @entity4755 , and/or Leu 11b. None of the B- or null cell @entity706 expressed the NK markers. In comparison with the NK-negative @entity784 , the NK-positive cases showed a predilection for the nasal and paranasal region. There was a more significant loss of the T-cell markers T3 (peripheral T cell) and T4 (T-helper cell) in NK-positive @entity706 . The difference was due to a high proportion of nasal/ @entity706 , which were associated with a frequent loss of T-cell markers, among the NK-positive cases. However, a similar degree of loss of T-cell markers was observed among NK-positive and NK-negative nasal/ @entity706 . We conclude that expression of NK markers occurs exclusively in a proportion of @entity784 , but not B-cell or null cell @entity706 . The reason this occurs predominantly in nasal and @entity706 is unknown.
