Abstract
The secretion of tumor necrosis factor (TNF)‐α from macrophages is regulated by both priming and triggering signals. We found that macrophages from mice lacking γδ T cells [T cell receptor (TCR) δ−/‐ mice], which lack the gene encoding the δ chain, produced only small amounts of TNF‐α in response to lipopolysaccharide (LPS) and showed a reduced level of expression of CD14. Pre‐incubation of macrophages from TCR δ‐/‐ mice with γδ T cells from their TCR δ+/‐ littermates restored their capacity to produce TNF‐α in response to LPS. The priming activity of γδ T cells was in part inhibited by neutralizing anti‐interferon (IFN)‐γ monoclonal antibodies. Collectively, these results suggest that γδ T cells play a role in priming macrophages to a steady state of activation via IFN‐γ secretion, which allows them to produce TNF‐α when exposed to LPS.
