Acanthamoeba

Section D. Figure 12. Host intracellular signaling in response to Acanthamoeba. Note that Acanthamoeba induces cell cycle arrest in the host cells by i) altering expression of genes as well as by ii) modulating protein retinoblastoma (pRb) phosphorylations. In addition, Acanthamoeba have also been shown to induce host cell death via phosphatidylinositol 3-kinase (PI3K). By secreting proteases, amoebae disrupt tight junctions by targeting zonula-1 and occludin proteins. MBP is mannose-binding protein; E2F is a transcription factor that controls cell proliferation through regulating the expression of essential genes required for cell cycle progression; PIP2 is phosphatidylinositol-4,5-bisphosphate; PIP3 is phosphatidylinositol-3,4,5-trisphosphate; Akt (protein kinase B)-PH domain, a serine/threonine kinase is a critical enzyme in signal transduction pathways involved in cell proliferation, apoptosis, angiogenesis, and diabetes.
