MALARIA PARASITES IN COMBINATION WITH INTERFERON-Γ INDUCE GLUCOCORTICOID RESISTANCE IN PULMONARY ENDOTHELIUM

Book - Dissertation

Due to their anti-inflammatory properties endogenous glucocorticoids (GCs) contribute to the control of the immune system. Exogenous GCs are used as anti-inflammatory therapeutics in patients suffering from a broad spectrum of inflammatory diseases. However, treatment failure due to GC resistance is frequently reported. Preliminary data show prominent GC resistance in a model of malaria-associated acute respiratory distress syndrome (MA-ARDS). MA-ARDS causesconsiderable suffering in patients, often results in death and is characterized by pulmonary edema and abundant inflammatory infiltrates consisting mainly of monocytes and lymphocytes. My project contains four aims: (i) defining the regulation of GC sensitivity in endothelial cells, (ii) defining the regulation of GC sensitivity in leukocytes in MA-ARDS, (iii) obtaining a genome-wide view of the effects of GC resistance in both endothelial cells and leukocytes and (iv) discovery ofthe biochemical and cellular mechanisms of this resistance. State-of-the-art technologies will be used, including new GC-resistant and GC-sensitive mouse models of MA-ARDS, in vitro and ex vivoGC sensitivity tests, genome-wide approaches (RNA-Seq and ChIP-Seq) and specific biochemical assays. Therefore, this project will uncover a new layer in the endogenous regulation ofinflammation. We also believe that these new insights will be instrumental for the design of novel therapies aiming at the restoration of GC sensitivity.
