A functionally grouped network analysis identified subnetworks of signaling pathways involved in the response to viral infections in the human cornea (Figures 2B, C), among them T cell related pathways (e.g., IKZF3, ZAP70, CD8A, and SIT1), T cell receptor signaling (e.g., CXCL9, FYN, and CXCL13), B cell related pathways (e.g., IGKC, IGLC2, and CD79A), and interferon gamma signaling pathways (e.g., IRF8, TNFSF4, and CCR7). Here, IFNG is linked to viral infectious disease.
