Anaplasma phagocytophilum(AP) is an obligatory intracellular bacterium that has a tropism for neutrophils and their precursors. AP induces the signal pathways that initiate the entry. Meanwhile, AP utilizes the caveolae-mediated bypass to establish the intemalization. After the entry, the AP actively modulates the autophagy, inhibits the pro duction of the reactive oxygen species, blocks the pathways of the apoptosis, down-regulates the IFN γ signal in the neutrophils and highly expresses molecules promoting the survival in itself. Through the molecular mechanisms above, the AP achieves survival in the neutrophils. The advances in the molecular mechanisms of the entry and survival of AP in the neutrophils are reviewed in this article.
