Dendritic Cells Activating a Lymphocyte
Here is a beautiful scanning electron micrograph of a human lymphocyte (pink) as it scans the surface of a dendritic cell (blue).
Lymphocytes are white blood cells, of which there are three types: B cells, T cells, and natural killer (NK) cells. Dendritic cells are located in the tissue and are responsible for stimulating the adaptive immune response via the activation of T cells.

This molecule is called Histamine. (C5H9N3)
It is an organic nitrogen compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter. Histamine triggers the inflammatory response. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.
