Figure 7. Characterization of cytokine expression in mammary tissue following intramammary challenge with ovalbumin.

Five responder cows were challenged in one quarter with 25 µg ovalbumin and mammary tissue was collected for RT-qPCR about 14 h later. A) Relative expression of cytokines associated with lymphocytes or considered as stimulating the expression of these cytokines by lymphocytes. B) Relative expression of genes coding chemokines and defense components. * significant difference (p<0.05; permutation test for paired samples) between challenged and control quarters.
