chemicals that are secreted from antigen-presenting cells then activate helper T cells describes the role of cell-to-cell communication during a response to an invasion of antigens.
Explanation: Antibodies are present on the surface of the cells, and binds specifically to antigens and can also engulf pathogen and process these cells presenting them to MHC class 2. This complex is activated by helper T cells to secrete antibodies and macrophages. This interaction of B-cell and MHC class 2 complex with helper T cell is cell-mediated immune response.
