in these experiments , we present additional evidence that suppressor lymphoid cells are present in lymph nodes and spleens of uv-irradiated mice and demonstrate that these cells are enriched after incubation on nylon wool columns , that they are inactive after treatment with anti-theta serum and complement , and that they are effective for at least 7 weeks after transfer to lethally x-irradiated mice .
