The innate immune system is responsible for sensing pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs) by several types of germline-encoded pattern-recognition receptors (PRRs). It has the capacity to help the human body maintain homeostasis under normal conditions. However, in pathological conditions, PAMPs or DAMPs trigger aberrant innate immune and inflammatory responses and thus negatively or positively influence the progression of cancer and cardiometabolic diseases. Interestingly, we found that some elements of innate immune signaling are involved in these diseases partially via immune-independent manners, indicating a deeper understanding of the function of innate immune signaling in these diseases is urgent. In this review, we summarize the primary innate immune signaling pathways and their association with cancer and cardiometabolic diseases, with the aim of providing effective therapies for these diseases.
Keywords: Cancer; Cardiometabolic diseases; Innate immune signaling; PRRs.
