IL-8 and MCP-1 mRNA expression within ZCL and SCL lesions. (A) Dot-plots show individual values of IL-8 and MCP-1 mRNA expression within ZCL (Δ) and SCL (▲) samples. Results are expressed as a ratio between levels of mRNA molecules in studied samples to those detected in normal skin. A horizontal bar indicates the median value of each group. (B) Correlation between IL-8 or MCP-1 mRNA levels and the age of lesions, their size, and the number of parasites they contain. Correlations between different variables were evaluated with the Spearman’s rank correlation test, r: correlation coefficient; p < 0.05 was considered statistically significant.
