Resposta imune a doenças infecciosas

Abstract

The interaction between pathogens and immune system occurs in a dynamic way with sophisticate mechanisms of evasion and immune control of infection, respectively. Therefore, it is a sine qua non condition to understand the complexity of this relationship in order to developed new strategies for infection control. Although the immune system has specialized mechanisms to control infection, different conditions involved in the interaction between immune system and pathogens can or cannot determine the development of disease. Interestingly, a protective immune response against one kind of parasite may not be protective against another. So, each pathogen presents a specific way of interaction with the immune system. The development of research in this area has contributed with a better comprehension of the immune system and pathogen relationship and opened perspective in improving the treatment with the development of new drugs and/or vaccines.
