Signaling pathways further modulated post-entry (soluble N-ethyl-maleimide-sensitive factor attachment protein receptors [SNAREs], such as syntaxin 6, EGFR, PI3K, AKT, MAPKs and c-Src, PTEN, various antiapoptotic factors (Mcl-1, Bcl-2 family members) [80, 81, 91, 100, 105, –, 111]) alter the expression of transcription factors (e.g., NF-κB, Sp1, AP1, STAT1, c-Fos, and others [77, 112, –, 117]) and this induces long-term changes in these cells (enhanced motility, enhanced survival, and differentiation [63, 65, 86, 118, –, 120]) following infection. Here, FOS is linked to infection.
