Abstract
- Enhanced natural killer (NK) activity and normal lymphocyte antibody-dependent cellular cytotoxicity (ADCC) were observed in 16 patients with a diagnosis of progressive systemic sclerosis (PSS). Higher NK activity levels were observed against NK-sensitive K562 target cells. while the NK- resistant P815. Daudi and Raji cell lines were not lysed. Cytofluorimetric studies and morphological analysis of peripheral blood lymphocytes (PBL) showed an increased number of CDI6 positive cells and large granular lymphocytes (LGL)1 indicating that the enhancement observed was probably attributable to an increase in the number of circulating NK cells.
