One of the best-known chemical mediators released from cells during inflammation is histamine, which triggers vasodilation and increases vascular permeability. Stored in granules of circulating basophils and mast cells, histamine is released immediately when these cells are injured.
As the dendritic cells migrate from the peripheries, they mature both functionally and phenotypically. They then stop the antigen capture while upregulating their expression of molecules such as CD86, CD80 and the chemokine receptor CCR7. They also release cytokines that promote inflammation such as IL-12 and TNF-Î±. Once in the lymph nodes, dendritic cells migrate to sites where T-cells and perform antigen presentation.
