In agreement with our proteomics data, analyses by ELISA revealed that the levels of galectin-1 were significantly reduced by malnutrition in the LP and LPi animals, relative to the CP group, whereas plasminogen levels were significantly increased in the thymic IF of malnourished and infected animals (LPi), in relation to the CP group (Figure 5). The gene discussed is PLG; the disease is malnutrition.
