There are several different colors on AV cords. On the cords below, yellow is for video and red and white are for the speakers. RGB component video cords below are also called RCA cords. The video signal is split into 3 channels.
Moreover, the dendritic cells directly activated both the subset of helper T cells as well as the killer T cells. Once activated by dendritic cells, the T cells could also interact vigorously with other antigen presenting B cells and macrophages to produce additional immune responses from these cells. The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.
Dendritic cells (DCs) are white blood cells forming part of the mammalian immune system. They process antigen material from pathogens and put it on their surface. There it touches other cells of the immune system. So, dendritic cells are antigen-presenting cells.They act as messengers between the innate and adaptive immune systems.Dendritic cells are present in tissues in contact with the external environment.These tissues are the skin, and the inner lining of the nose, lungs, stomach and intestines. They can also be found in an immature state in the blood.here it touches other cells of the immune system. So, dendritic cells are antigen-presenting cells.
