Inflammation is an innate immune response triggered by harmful stimuli, such as pathogens, tissue injury, or toxins. The purpose is to eliminate the source of infection and initiate the healing process. However, an excessive acute inflammatory response can lead to severe and life-threatening complications, as seen during recent pandemics. In the context of viral infections, the activation of the TLR7/8 signaling pathway has been implicated in excessive cytokine secretion. In this study, we aimed to replicate the perturbed inflammatory environment resulting from the activation of the TLR7/8 specific agonists, imiquimod, and resiquimod.
We utilized macrophage-like cells, as macrophages are the first responders during infections and secrete key pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β) to recruit immune cells to th.. View more»
