RT Journal Article SR Electronic T1 Variations in interferon production by lymphocytes from patients with chronic lymphatic leukaemia JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 768 OP 771 DO 10.1136/jcp.25.9.768 VO 25 IS 9 A1 A. M. R. Mackenzie YR 1972 UL http://jcp.bmj.com/content/25/9/768.abstract AB In a group of patients with chronic lymphatic leukaemia leucocyte cultures showed a diminished capacity to synthesize interferon when compared with controls. The leucocyte culture with the lowest capacity to synthesize interferon came from the patients with the highest peripheral blood lymphocyte counts and vice versa. These results are presented as indirect evidence that T lymphocytes are more competent producers of interferon than B lymphocytes.
