Suppressor Factors, Immunologic

**Definition:** Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-J) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory.
