Suggested repression of fungal spore binding; repression of bacterial binding; increased allergen binding and uptake; neutralization of viral infectivity; inhibition of proliferation and migration of human lung adenocarcinoma cell line trough suppression of EGF signaling; inhibition of the expression of inflammatory cytokines through TLR4 signaling in corneal epithelial cells. Here, TLR4 is linked to lung adenocarcinoma.
