Place these events in the pathogenesis of contact dermatitis in order, with 1 being the first step.Sensitized T lymphocytes recognize the antigen and make cytokine chemicals.Cytokine chemicals attract macrophages, dendritic cells, and cytotoxic T lymphocytes to the site of the antigen.Chemicals are released from phagocytic cells and cytotoxic T cells, resulting in host tissue damage.A chemical is absorbed through the skin.
The antigen is identified by a dendritic cell.

What will be an ideal response?
