Lymphokines include macrophage migration inhibition factor (MIF), macrophage activation factor (MAF), leucocyte migration inhibition factor (LMIF), leucocyte adherence inhibition factor (LAIF), chemotactic factor, transfer factor and interferon. The MIF and MAF help in the accumulation of macrophages at the site of reaction. The resulting erythema and induration form the basis of skin tests. Administration of transfer factor to non-sensitized individuals leads to specific sensitization. Interferon interferes with virus multiplication in host cells.

Hypersensitivity reaction mediated by T cells is called type IV reaction.
