In troduc tion For a better understanding of the pathogenic mechanismof infectious diseases it is important to know the molecular basis of how the host responds to microbial pathogens and eliminates them. Recent advances in immunology and molecular biology have led to the discovery of a large number of cytokines and cell surface molecules, which allows us to understand such pathogenic mechanism...
