Invariant natural killer T (iNKT) cells are capable of recognizing lipid antigens and secreting Th1/Th2 cytokines. Deficiency in iNKT cell number or function has been partially implicated in susceptibility to some infectious diseases, such as tuberculosis. We evaluated iNKT cells in paracoccidioidomycosis, another chronic granulomatous disease endemic in(More)
To determine the effects of saturated and unsaturated fatty acids in phosphatidylcholine (PC) on macrophage activity, peritoneal lavage cells were cultured in the presence of phosphatidylcholine rich in saturated or unsaturated fatty acids (sat PC and unsat PC, respectively), both used at concentrations of 32 and 64 microM. The treatment of peritoneal(More)
Dietary soy lecithin supplementation decreases hyperlipidemia and influences lipid metabolism. Although this product is used by diabetic patients, there are no data about the effect of soy lecithin supplementation on the immune system. The addition of phosphatidylcholine, the main component of lecithin, to a culture of lymphocytes has been reported to alter(More)
Managing bioinformatics experiments is challenging due to the orchestration and interoperation of tools with semantics. An effective approach for managing those experiments is through workflow management systems (WfMS). We present several WfMS features for supporting genome homology workflows and discuss relevant issues for typical genomic experiments. In(More)
Bioinformatics experiments are typically composed of programs in pipelines manipulating an enormous quantity of data. An interesting approach for managing those experiments is through workflow management systems (WfMS). In this work we discuss WfMS features to support genome homology workflows and present some relevant issues for typical genomic(More)
Distinct glycolipid profiles are described in microorganisms, which have been shown to modulate the innate immune system. We tested the hypothesis that glycosphingolipids from Paracoccidioides brasiliensis have immunomodulatory properties on monocytes and dendritic cells of two groups of healthy individuals, one cured of paracoccidioidomycosis in the past(More)
