Pulmonary dendritic cells: thinking globally, acting locally

Abstract

The phrase “think globally, act locally” was coined in the early 1970s and directed individuals to clean up their local environment with the ultimate goal of improving the health of the entire planet. Several recent studies indicate that similar considerations apply to the immune system, in which small numbers of leukocytes, such as pulmonary dendritic cells, can modify the local immune environment in the lung and promote a positive outcome for the organism.
