Virus-specific CD8+ T cells play an important role in the course and outcome of these viral infections and it is hypothesized that altered or impaired differentiation of virus- specific CD8+ T cells contributes to the development of persistence and/or disease progression. A deeper understanding of the mechanisms responsible for functional differentiation of CD8+ T cells is essential for the generation of successful therapies aiming to strengthen the adaptive component of the immune system.展开更多

Actually, for the American anthropologist, "no history without culture." But the question is to focus on the different discursive forms which transforms the events of history in historiography, in a (referential and not fictional) story; these different (often poetic) forms of historiography shape a collective and cultural memory. The Greek case is particularly significant under that point of view as far as historiography is always situated between oral tradition and written tradition (Jack Goody), between poetic forms and forms of prose, with an important political, social, religious, and ideological impact.展开更多
