The clustering analysis confirmed the previous findings, revealing that PCa patients exhibit a distinct expression profile of cytokines IL-4, IL-5, IL-6, IL-10, IL-1β, IL-17A, IL-12p70, MCP-1 (CCL2), MIP-1α (CCL3), MIP-1β (CCL4), TNF-α, and IFN-γ compared to healthy individuals. This evidence concerns the gene IL1B and posterior cortical atrophy.
