And leucocyte.Macrophage is the main component for the leucocyte that tumour is arrived in infiltration.Macrophage in tumor tissues, i.e. tumour phase
It closes macrophage (Tumor-associatedmacrophage, TAM), is played with the relationship of tumour and in tumour a variety of
Function is just by in-depth study.The different state of activation of tumor-associated macrophage determines that it is that performance is antitumor in tumour
Effect or Tumor acceleration.On the one hand, it can be played by phagocytosis, killing tumor cell and submission tumor associated antigen immune
Monitoring and antitumor action;On the other hand, tumour growth and blood can be promoted by discharging many chemotactic factor (CF)s and cell factor
Pipe generates, and can promote invasion and metastasis of tumor with matrix degradation.
Macrophage is at least divided into two types: M1 type, i.e., the macrophage of classical activation
(Classicallyactivated macrophage) and M2 type, i.e., the macrophage (Alternatively of alternative activation
activated macrophage).M1 type macrophage produces under the induction of bacterium or its product lipopolysaccharides or interferon-γ
It is raw, show themselves in that the ability of high present antigen;Hypersecretion interleukin 12 and interleukin 23 and its I type then induced
Immune response is high: the ability of high yield toxigenicity intermediate product (nitric oxide, reactive oxygen intermediates).Therefore, M1 type macrophage is thin
Born of the same parents are considered to have killing bacterium and tumour cell and the ability that can secrete a variety of pro-inflammatory cytokines.And M2 type macrophage is thin
Born of the same parents can be produced by inductions such as interleukin-4, interleukin-13, glucocorticoid, transforming growth factor-β and prostaglandin E2s
