Functional modulation of dendritic cells in different pathophysiological conditions

Abstract

Dendritic Cells (DCs) are the major antigen presenting cells and the possibility of their generation in vitro has renewed the interest in immunotherapy protocols. However, their study shows that they are functionally heterogeneous and under poorly defined control mechanisms. The unravelling of such mechanisms may allow DCs exploitation in more efficient immunotherapy protocols. Therefore, the aim of the present project is the study of human DCs differentiation in vitro. in seven sub-projects, evaluating their function and membrane phenotype, under the effect of periodontal bacteria, different temperatures, apoptotic cells, heat-shock proteins, tumor cells, jaundice, hormones (specifically melatonin), and immunomodulatory drugs (specifically cyclophosphamide).
