Abstract
What ismolecular immunology ? Is it strictly speaking the study of immune system molecules and their interactions ? Undoubtedly. An important part of immunology deals with receptors and their ligands, and the transmission of signals from the cell surface to the nucleus. Today, this is one of the fields of biology where we can best see how molecular aggregates assemble and dissociate in highly specific combinatorics. But it is not this restrictive vision that I retain. Molecular immunology is not a specialized field of immunology. On the contrary, it refers to the fact that immunology is part of the molecular biology movement , which in fact broadens its scope.
