The role of the two types of tumor necrosis factor (TNF) receptors, TNF‐RI and TNF‐R2, in mediating the capacity of TNF to stimulate nerve growth factor (NGF) production in fibroblasts has been investigated. Although Swiss 3T3 cells express both the TNF‐R1 and TNF‐R2, an agonistic anti‐TNF R1 antibody, but not an agonistic anti‐TNF‐R2 antibody, increases the NGF mRNA level and stimulates the production of NGF protein in the cells. Treatment of the cells with a combination of anti‐TNF‐R2 antibody and interleukin‐1β (IL‐1β) does not increase the NGF production induced by IL‐1β alone, although TNF's activity to stimulate NGF production is markedly enhanced by IL‐1β. Furthermore, simultaneous addition of the both antibodies does not increase the NGF production above that observed with the anti‐TNF‐RI antibody, indicating that TNF‐R1 alone mediates the TNF's activity to stimulate NGF production in fibroblasts.
