Hemopoietic progenitors, coming from bone marrow through the blood stream, colonize the thymus where they are induced to differentiate to T lymphocyte. To succeed in becoming a functional mature T lymphocyte, T cell precursors (thymocytes) must undertake a number of differentiation steps and pass through stage specific checkpoints, which ensure maturation only of appropriate cells. Denise\u2019s project was aimed at characterizing the microdomain in the thymocyte responsible for communicating to the cell interior and the nucleus that the maturing T cell has the requirement to pass through the first quality control checkpoint in T cell development, namely <span style=\"font-family: Symbol\">b<\/span> selection. This checkpoint ensures that only thymocytes with productive somatic rearrangement of the gene encoding the <span style=\"font-family: Symbol\">b<\/span> chain of the T cell receptor (TCR) progress in the differentiation process. The TCR confers clonal specificity to each T cell and represents the molecular basis for specific immunity toward pathogens, like virus, bacteria, etc. Denise studied how the pre-TCR, which is composed of the rearranged <span style=\"font-family: Symbol\">b<\/span> chain associated with the pre-T <span style=\"font-family: Symbol\">a<\/span> chain, transduces the differentiation signal to the cell interior. A peculiarity of the pre-TCR is to be active spontaneously once it reaches the plasma membrane and this property, according to Denise\u2019s study, is facilitated by segregation in particular microdomains of the cell plasma membrane. These domains, which are enriched in glycosphingolipids and have peculiar biophysical properties, are defined as plasma membrane lipid rafts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>on July 17, 2007 PhD Program \u201cMolecular Medicine \u2013 Basic and Applied Immunology\u201d S.Raffaele Scientific Institute, Milan, Italy Thesis defense: July 17 th, 2007 Title: \u201cSubcellular microdomains in T cell development\u201d Denise has been accepted a 4 year position as Staff Scientist at the Italian Institute of Technology, Genoa.
