The cellular response to recognition of microbial products.

It can be seen that many cell types of the innate immune system have receptors on their surface that can recognise microbial products and therefore detect that we have been infected. Obviously recognition of infection is useful only if it results in a response to the infection that will ideally eliminate the pathogenic organism or at the very least limit the replication and spread of the pathogen. There are a number of ways in which different cells can respond to recognition of pathogens, and one of these is phagocytosis.
