Observation en immunofluorescence d'une cellule infectée par Listeria monocytogenes. En bleu: marquage des protéines de surface de Listeria qui permet de visualiser les bactéries. En rouge et vert: marquage de l'actine, une protéine qui forme le cytosquelette des cellules. Les Listeria utilisent l'actine cellulaire pour former des "comêtes" et se déplacer à l'intérieur des cellules qu'elles infectent.
Cell infected by Listeria monocytogenes. The surface proteins (in blue) of Listeria enable us to view the bacteria. Actin, a constituent protein of cells, is shown in red and green.
Antibody-based anti-tumor immunotherapy that aims at identifying the human FcγRs involved in melanoma and/or breast cancer immunotherapy, and at identifying the effector population(s) responsible for tumor destruction
