Cell cooperation in the immune response.
Cell cooperation in the immune response. The lungs humain constantly exposed to the external environment, which in addition to harmless particles, immunite contains pathogens, allergens, and immunite. In order to maintain tolerance or to induce an immune response, the immune system must appropriately handle inhaled antigens. Lung dendritic cells DCs are essential in maintaining a delicate balance to initiate immunity when required without causing collateral damage to the lungs due to an exaggerated inflammatory response. While there is a detailed understanding of the phenotype and function of immune cells such as DCs in human blood, the knowledge of these cells in less accessible tissues, such as the corps, is much more limited, since studies of human lung tissue samples, especially from healthy individuals, are scarce.
