Macrophage
The structure on the macrophage that activates T cells is the Major Histocompatibility Complex (MHC) molecule, specifically MHC class II. Macrophages present processed antigens on these MHC class II molecules to CD4+ T helper cells, initiating T cell activation. This interaction is crucial for the adaptive immune response, as it helps T cells recognize and respond to specific pathogens. Additionally, co-stimulatory signals from other surface proteins on the macrophage are necessary for full T cell activation.

macrophage
The white blood cell described is likely a macrophage. Macrophages are immune cells that engulf and digest foreign particles, such as cell debris, dust, pollen, and pathogens, through a process called phagocytosis. They play a vital role in the immune response by helping to eliminate harmful substances from the body.
