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 The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.
The T helper cells (Th cells) are a type of T cell that play an important role in the immune system, particularly in the adaptive immune system. They help the activity of other immune cells by releasing T cell cytokines.These cells help suppress or regulate immune responses.elper T cells are capable of influencing a variety of immune cells, and the T cell response generated (including the extracellular signals such as cytokines) can be essential for a successful outcome from infection.
