Secretory component (SC) acts as receptor for polymeric IgA (pIgA) and pIgM on the basolateral face of secretory epithelia. This study showed that both the production and surface membrane expression of SC were additively up‐regulated by tumour necrosis factor‐α (TNF) and gamma inferreron (IFN‐γ) in a human colonic cell line (HT‐29m2). TNF likewise enhanced membrane expression of HLA class I determinants. Moreover, TNF augmented synergistically the IFN‐induced dc novo synthesis of HLA class II (DR) molecules. These data suggest that there are different regulatory mechanisms for the action of TNF and IFN and for the expression of HLA‐DR and SC/HLA class I. Addition of actinomycin D abolished the cytokine‐mediated increase of SC synthesis and expression. This observation suggested that transcriptional events are required for the cytokine‐mediated up‐regulation of SC.
