title: [Defense mechanism and immunity].
abstract: Monocyte/macrophage (m phi) or mononuclear phagocytic system(MPS) play one of the key roles in defense mechanisms in human as well as animals. Informations as to their biological functions and significance in defense mechanisms or immune systems have increased. However, some of the details are still unknown and/or controversial. Prof. Takahashi lectured on some new findings: development of m phi precedes that of monocyte, factors regulating differentiation of m phi, differences between tissue m phi and monocyte/m phi and so on. He also stressed the complexity of the development and differentiation of monocyte/m phi. Prof Yamamoto lectured on a new factor, S19 ribosomal protein, which enhances migration of monocytes and connects natural immunity and acquired immunity. Following these lectures, all participants realized the complexity and also the mystery of defense mechanisms of our bodies.
