B cells are not involved in contact dermatitis, as they do not produce antibodies or form immune complexes.
T cells are the type of cells that mediate contact dermatitis, which is a type of type IV hypersensitivity. T cells recognize the poison ivy antigens that bind to the skin proteins and release cytokines that recruit macrophages and other inflammatory cells. This leads to a delayed and localized reaction that manifests as erythema, edema, vesicles, and pruritus.
T cells are not the same as B cells, as they have different receptors and functions in the immune system.
Mast cells are not involved in contact dermatitis, as they do not express IgE antibodies or release histamine.
