Immunostaining for CD3+ T cell. 7a: Spleen tissue from 2CLP rats serving as positive control for CD3+ T cell immunostainin 7b: left: minimal lymphocytic infiltration of the lung tissue in SO rat. Middle: moderate infiltration in a 2CLP lung rat after SV/luc administration. Right: moderate infiltration in a 2CLP lung rat not treated with SV/luc. Note that the degree of lymphocyte infiltration is similar in the middle and right panels, suggesting that it is part of the disease process rather than being induced by the vector.
