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 The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.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: A Basic Review *last updated May 2003 Prepared by: Eric Wieder, PhD MD Anderson Cancer Center Houston, TX USA What is a dendritic cell? Dendritic cells are antigen-presenting cells (APCs) which play a critical role in the regulation of the adaptive immune response.he first category of DCs function is antigen presentation and activation of T cells. The second category of DC function is not as well established, but it has been suggested that a different class of DCs exist with the function of inducing and maintaining immune tolerance.
