The immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs). Cells may be unhealthy because of infection or because of cellular damage caused by non-infectious agents like sunburn or cancer.he immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs).
