T Cell: Explains its role in initiating immune responses. Macrophages: Describes their function in phagocytosis and antigen presentation. Important Immune Activities: Lists key functions of macrophages, including phagocytosis, antigen presentation, and cytokine secretion. T Cell Activation: Explains how T cells activate macrophages. An Activated Macrophage: Describes the benefits of an activated macrophage, such as increased efficiency in fusing phagosomes with lysosomes and increased production of free radicals and NO within the lysosome. Dendritic Cell and T Cell Interaction: Discusses the conditions for a successful interaction between dendritic cells and T cells. Cytokine Release: Mentions the role of cytokines in immune responses.
