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 The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.
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.
