The importance of the protein corona formed around nanoparticles upon entering a biological fluid has recently been highlighted. This corona is, when sufficiently long-lived, thought to govern the particles' biological fate. However, even this long-lived "hard" corona evolves and re-equilibrates as particles pass from one biological fluid to another, and may be an important feature for long-term fate. Here we show the evolution of the protein corona as a result of transfer of nanoparticles from one biological fluid (plasma) into another (cytosolic fluid), a simple illustrative model for the uptake of nanoparticles into cells. While no direct comparison can be made to what would happen in, for example, the uptake pathway, the results confirm that significant evolution of the corona occurs in the second biological solution, but that the final corona contains a "fingerprint" of its history. This could be evolved to map the transport pathways utilized by nanoparticles, and eventually to predict nanoparticle fate and behavior. © 2011 American Chemical Society. Source

The ITN TIMCC brings together eight expert teams from different disciplines within Immunology, Genetics and Oncology, to provide substantive and methodological training in the analysis of the role of the Tumor Infiltrating Myeloid Cell Compartment (TIMCC) of the innate immune system. Leukocytes recruited to (pre)malignant tissues are mainly myeloid cells. They can either prevent or functionally contribute to cancer development. However, the mechanisms underlying pro- versus anti-tumor programming of neoplastic tissues by these immune cells remain obscure. The ITN TIMCC aims to improve anti-tumor therapy by defining general and tumor type specific molecular and cellular immunological pathways (e.g signal transduction and downstream effector pathways) in tumor development and during therapeutic intervention based on an extensive analysis of the infiltrating myeloid cell compartment in human tumor biopsies using a large variety of techniques and functional analysis of the corresponding models of a variety of human tumors, affecting different organs, in a unique cohort of genetically modified mice treated with different types of anti-tumor therapy. The program will train the appointed researchers in a variety of methodology and technology from genomic technologies and bioinformatics via genetically modified mice to the design and application of therapeutic strategies to understand and manipulate the many interactions of the myeloid cell compartment with developing tumors. By defining underlying molecular and cellular pathways new targets will be identified to be explored by the participating SMEs. The program will deliver young researchers equipped with a broad knowledge in immunology, genetics and oncology and insight in the complexity of translational medicine therefore better prepared to meet new challenges in the field.
