Cells Exposed to Sublethal Oxidative Stress Selectively Attract Monocytes/Macrophages via Scavenger Receptors and MyD88-Mediated Signaling

The innate immune system responds to endogenous molecules released during cellular stress or those that have undergone modifications normally absent in healthy tissue. These structures are detected by pattern-recognition receptors, alerting the immune system to "danger." In this study, we looked for early signals that direct immune cells to cells undergoing stress before irreversible damage takes place. To avoid detecting signals emanating from …
