Impact of neonatal malnutrition on expression TLR-9, NF-kB and cytokines of macrophages infected in vitro with methicillin resistant Staphylococcus aureus
2019
Abstract Early nutritional aggressions promote epigenetic adjustments that culminate in the loss of phenotype plasticity (with permanent long-term modifications). Maternal diet and inadequate neonatal nutrition can result in fetal programming that presents susceptibility to infections in adult life. Thus, it becomes essential to verify the impacts of neonatal malnutrition (even following nutritional replacement) on the immunological response to methicillin resistant Staphylococcus aureus (MRSA) infections. Male rats were divided into two distinct groups: Nourished and Malnourished. After isolation of mononuclear cells, four systems were established: negative control, positive control and two testing systems, (MSSA and MRSA). Tests were performed to analyze expression of TLR-9, NF-kB, IL-1β, IL-18 and IL-33. For statistical analysis, we used the Student t and ANOVA tests p
