 Cancer cells use selectins, chemokines and their receptors for invasion, migration and metastasis.On the other hand, many cells of the immune system contribute to cancer immunology, suppressing cancer.Molecular intersection between receptors of steroid hormones, which have important effects on cellular development, and transcription factors that play key roles in inflammation, such as NF-κB, may mediate some of the most critical effects of inflammatory stimuli on cancer cells.
