Modelling the cell-mediated immunity in homograft refection.

Lymphocytes which become sensitised at the periphery travel to the regional lymph nodes where they initiate an immunological response by increasing the production of immuno-competent lymphocytes. These lymphocytes migrate into the tissues via the blood stream and bring about the destruction of target cells. These notions, in the present analysis, are translated into a simple mathematical model. The model specifically considers the lymphocyte memory and increased secondary response.
