The innate immune system has the basic function of identifying and eradicating microbial invaders and alerting the adaptative immune system to their presence. In this study, the porcine intestinal innate immune response was evaluated by analysing the expression of TLRs, cytokines and chemokines in two porcine epithelial cell lines from different regions:(More)
The proposed protocol presents a comprehensive approach for large-scale qualitative and quantitative analysis of glycated proteins (GP) in complex biological samples including biological fluids and cell lysates such as plasma and red blood cells. The method, named glycation isotopic labeling (GIL), is based on the differential labeling of proteins with(More)
Despite continuous advances in hyperglycemia treatments, a precise control through monitoring of glucose and glycated hemoglobin remains in most diabetic patients as the diagnosis/prognosis tool. An alternative perspective could be the discovery and quantitation of new blood glycated proteins formed by nonenzymatic reaction with circulatory glucose. As a(More)
Protein glycation is a nonenzymatic modification that involves pathological functions in neurological diseases. Despite the high number of studies showing accumulation of advanced end glycation products (AGEs) at clinical stage, there is a lack of knowledge about which proteins are modified, where those modifications occur, and to what extent. The goal of(More)
Glucose is the predominant source of energy in cells. However, a chronic high glucose exposure of proteins modifies a number of biological pathways, known as glucotoxicity. Several studies have suggested that this impaired protein function is associated in part to protein glycation. However, despite the evidence of this glucotoxicity on tissues and cells,(More)
of proteins, non-enzymatic glycation is one of the less frequently studied in proteomics. Glycated proteins are formed by a non-enzymatic reaction between reducing carbohydrates (e.g., glucose, fructose, ribose or derivatives such as ascorbic acid) with amino groups located in N-terminal position or in lysine and arginine residues (Figure 1) [1].
