A Sequential Model of Host Cell Killing and Phagocytosis by Entamoeba histolytica
The protozoan parasite Entamoeba histolytica is responsible for invasive intestinal and extraintestinal amebiasis. The virulence of Entamoeba histolytica is strongly correlated with the parasite's capacity to effectively kill and phagocytose host cells. The process by which host cells are killed and phagocytosed follows a sequential model of adherence, cell killing, initiation of phagocytosis, ...
متن کاملAmoebic PI3K and PKC Is Required for Jurkat T Cell Death Induced by Entamoeba histolytica
The enteric protozoan parasite Entamoeba histolytica is the causative agent of human amebiasis. During infection, adherence of E. histolytica through Gal/GalNAc lectin on the surface of the amoeba can induce caspase-3-dependent or -independent host cell death. Phosphorylinositol 3-kinase (PI3K) and protein kinase C (PKC) in E. histolytica play an important function in the adhesion, killing, or ...
متن کاملApoptotic killing and phagocytosis of host cells by the parasite Entamoeba histolytica.
The ability of Entamoeba histolytica to kill and phagocytose host cells correlates with parasite virulence. This study addressed the role of apoptotic cell killing and host cell phosphatidylserine exposure in the subsequent phagocytosis of Jurkat T cells by E. histolytica. Ingested host cells were apoptotic, as evidenced by the activation of caspase 3 in 88% +/- 3% (mean and standard deviation ...
متن کاملPRELIMINARY COMPARATIVE STUDY OF ENTAMOEBA HISTOLYTICA AND ENTAMOEBA DISPAR BY PCR TECHNIQUE IN IRAN
It has been suggested that two distinct species exist within what was originally known as Entamoeba histolytica and E. dispar. These are Entamoeba dispar for the nonpathogenic and E. histolytica for the pathogenic fonn. Differentiation of these two organisms is of great clinical importance since they are morphologically indistinguishable and both fonns can infect the human intestinal cavity...
متن کاملEntamoeba histolytica-induced dephosphorylation in host cells.
Activation of host cell protein tyrosine phosphatases (PTPases) and protein dephosphorylation is an important mechanism used by various microorganisms to deactivate or kill host defense cells. To determine whether protein tyrosine dephosphorylation played a role in signaling pathways affecting Entamoeba histolytica-mediated host cell killing, we investigated the involvement of PTPases during th...
