To further confirm the difference in expression levels of other cytokines (such as pro-inflammatory factors IL-1β, IL-6, IFN-γ, anti-inflammatory factors IL-4, IL-10, TGF-β1) in the kidneys during infection with different genotypes of C. albicans, we conducted real-time fluorescence quantitative PCR (qPCR) experiments (Nailis et al. 2006). The gene discussed is IL4; the disease is infection.
