Abstract

- The high number of /-expressing T cells found in the epithelial lining layer suggests that they form a first line of defence against invading pathogens. To evaluate the role of / T cell-receptor (TCR)-expressing cells in cutaneous infection caused by Staphylococcus aureus, mice lacking /-expressing T cells (TCR/) were inoculated intradermally with S. aureus, and compared with S. aureus-infected congeneic TCR+/ control mice. The number of bacteria recovered from the skin of TCR/ mice was significantly higher (P = 0·0071) at early time-points after inoculation compared to the number of bacteria isolated from infected TCR+/ congeneic controls. Nevertheless, inflammatory responses measured as serum IL-6 levels, were significantly lower in TCR/ mice than in the control group. A possible explanation for this discrepancy was the observation of significantly decreased overall numbers of infiltrating cutaneous T lymphocytes, which are important producers of IL-6. These results support the notion that the /-expressing T cells that reside at the epithelial lining layer of the skin is of importance for early containment of the bacteria, thereby limiting their replication and spread.
