Immunity is a state of protection mechanism against various kinds of infectious diseases. The immune system is a tightly regulated complex network of various cells (lymphoid, reticular, dendritic and epithelial cells), which are communicating with each other by soluble cytokines mediators. Innate and adaptive immunity works synergistically against the various infectious agents to protect the body. Before an infection, innate immunity is developed in the body which prevents or eliminates the pathogen within hours. Adaptive immunity is another form of immunity which develops in response to infection and adapts to recognize, eliminate, and then remember the invading pathogen. Various chemicals such as deltamethrin, tributyltin have been reported to actively interfere with the activation of complex signaling pathways of the immune system. Immune system provides the protection against infectious diseases but in case of strong pathogenic microorganism, immune system is not able to protect the body from infection which leads todiseases.Infectious diseases remain a major problem worldwide.
