The response of an immune system to a challenge is modified by presenting the system with a nucleoside in a concentration selected to have an effect on a B7 marker that is inverse from the effect of the challenge. Contemplated challenges include allergens, neoplasm, virus, bacteria, infestation, and autoimmune reaction. Molecular markers of particular interest are B7-1 and B7-2. Preferred nucleosides are Ribavirin and Ribavirin analogs, especially provided within a concentration range between about 0.2 :M and about 5 :M, respectively, in a fluid containing cells expressing the B7 marker. |
