As listed in Table 4, isolated amniochorion tissues have shown to produce a wide variety of cytokines classified into proinflammatory, lymphocyte-derived, macrophage-derived, anti-inflammatory, antiviral, and chemoattractive cytokines constitutively or in response to diverse stimuli with physical stretching, PGE2, IL-1β, TNF-α, and bacterial products (LPS), and infections with bacteria (Escherichia coli [115], Streptococcus agalactiae [116], and Ureaplasma urealyticum [117]) and viruses (influenza virus and NewCastle disease virus [118]) [119–127]. This evidence concerns the gene TNF and infection.
