Host-pathogen interactions cover virulance mechanisms of microbial pathogens and immunological responses of the host.
Cancerous growth of human cells is under strict control of the immune system, yet cancer cells often find a way to evade or even exploit the immune system for their advantage. The contribution of the immune system to development and progression of cancer is an area of great interest to the scientific community, since drugs that target several points in the immune cascade were developed, allowing for the inhibition or stimulation of immune functions in a manner that is detrimental to cancer cells.
