D in most HAT patients, since miR-144* has been reported to be involved in the inhibition of TNF-alpha and IFN-gamma production and T-cell proliferation [58]. Mir27b is enriched in liver 10781694 cells, is a negative regulator of several mRNAs involved in lipid metabolism [59], and is also involved in the control of angiogenesis [60]. An increase in miR27b is required for expression if inducible nitric oxide synthase (iNOS) during infection of epithelial cells by Crytosporidium parvum: miR27b decreases expression of a negative regulator [61,62]. In contrast, mir27b decreased in HAT patient ASP-015K web peripheral blood. In conclusion, we have shown that T gambiense infection of humans causes alterations in the expression of miRNA in peripheral blood leucocytes. Unfortunately, however, no miRNA could be specifically linked to HAT infection or used to predict the stage of the disease. Instead, several of the strongly affected miRNAs have been linked previously to changes in cellular proliferation, which might reflect the lymphocyte activation that is seen in the disease.Supporting InformationTable S1 mRNAs with significantly altered abundance in sleeping sickness patients.

The strong interest on iron nutrition and metabolism in both developing and developed nations arises from the need to find a remedy to the widely diffused metabolic disorders of iron deficiency and overload. Several interdisciplinary studies of the various aspects of iron nutrition, physiology, and biochemistry have been carried out. Particular attention has been devoted to studies about dietary and physiologic CP21 custom synthesis factors that modulate the efficiency of iron absorption with the aim of elucidating molecular mechanisms of intestinal absorption of iron. The purpose is to formulate diets and dietary practices that enhance iron availability and to unravel the precise pathways and general features of intestinal iron absorption mechanism. Despite many years of intense studies, many of these aspects are still speculative and hypothetical.Dietary iron absorption can be divided into intestinal uptake (i.e., transport across the apical membrane of enterocytes) and transfer (i.e., translocation through the cytoplasm and across the basolateral membrane into the portal circulation). Anyway, consensus has not yet been reached on the comprehensive molecular mechanisms involved in iron passage into, across, and out of the mucosal epithelial cells. In mammals, the majority of iron is present as hemoglobin in erythrocytes. The phagocytosis of senescent erythrocytes mediated by macrophages ensures that a significant portion of the iron is recycled. Nevertheless, a certain amount of iron is daily lost through epithelial exfoliation, thus requiring compensation by dietary iron absorption through duodenal enterocytes.
