Place in order the steps involved in cell-mediated immune response to an exogenous antigen. (a) costimulation and activation of helper T cells (b) presentation of antigen to helper T cells (c) elimination of invaders through the release of granzymes, perforin, granulysin, or lymphotoxin or by attraction and activation of phagocytes (d) proliferation and differentiation of helper T cells to produce a helper T cell clone (e) antigen processing by dendritic cells, macrophages, or B cells (f) recognition of antigen fragments associated with MHC-II molecules by T-cell receptors (g) secretion of cytokines such as interleukin-2 by activated helper T cells (h) migration of antigen-presenting cells to lymphatic tissue (i) activation of cytotoxic T cells
