Natural killer" (NK) effector cells and large granular lymphocytes (LGL) are found inside rat renal allografts during rejection. Their appearance in situ precedes the appearance of cytotoxic T lymphocytes, and concomitantly with their influx in the allograft, the NK activity and the LGL are depleted

β¦ Synopsis
Monoclonal antibody Anti Leu 7 has been used to enumerate peripheral blood N K cells in
20 renal allograft recipients. Blood was taken preoperatively and three times per week for the first month a f e r transplantation; separated mononuclear cells were stained with Anti Leu 7 then analysed on a fluorescence activated cell sorter. Results were related to acute rejection episodes diagnosed clinically and confirmed by Trucut biopsy of grafs. A reduction in the number of Leu 7 positive cells occurred postoperatively. Nineteen out of 20 patients showed a rise in number of circulating N K cells during acute rejection episodes.
