Ki-67 is expressed in multiplying forms of Schistosoma mansoni, but not in snail host tissues.
Ki-67 is a protein expressed in the nucleus of several species during cell-division, being absent during the GO resting phase of the cellular cycle. During attempts to disclose mitosis in the so-called " amebocyte-producing organ " in Biomphalaria glabrata infected with Schistosoma mansoni, the parasite multiplying forms appeared strongly marked for Ki-67, while the snail tissues were completel...
متن کاملInvolvement of the Cytokine MIF in the Snail Host Immune Response to the Parasite Schistosoma mansoni
We have identified and characterized a Macrophage Migration Inhibitory Factor (MIF) family member in the Lophotrochozoan invertebrate, Biomphalaria glabrata, the snail intermediate host of the human blood fluke Schistosoma mansoni. In mammals, MIF is a widely expressed pleiotropic cytokine with potent pro-inflammatory properties that controls cell functions such as gene expression, proliferatio...
متن کاملPolyethyleneimine (PEI) Mediated siRNA Gene Silencing in the Schistosoma mansoni Snail Host, Biomphalaria glabrata
An in vivo, non-invasive technique for gene silencing by RNA interference (RNAi) in the snail, Biomphalaria glabrata, has been developed using cationic polymer polyethyleneimine (PEI) mediated delivery of long double-stranded (ds) and small interfering (si) RNA. Cellular delivery was evaluated and optimized by using a 'mock' fluorescent siRNA. Subsequently, we used the method to suppress expres...
متن کاملSchistosoma mansoni Enhances Host Susceptibility to Mucosal but Not Intravenous Challenge by R5 Clade C SHIV
BACKGROUND The high prevalence of HIV-1/AIDS in areas endemic for schistosomiasis and other helminthic infections has led to the hypothesis that parasites increase host susceptibility to immunodeficiency virus infection. We previously showed that rhesus macaques (RM) with active schistosomiasis were significantly more likely to become systemically infected after intrarectal (i.r.) exposure to a...
متن کاملCD93 is Selectively Expressed on Human Myeloma Cells but Not on B Lymphocytes
Background: CD93 has originally been known as a C1q receptor, and many studies have demonstrated that CD93 is expressed on hematopoietic stem cells, B cell progenitors, myeloid and monocytic cells. Moreover, CD93 is shown to be expressed on long-lived plasma cells, and CD93 deficient-mice display an impairment in plasma cell development. Objective: To investiga...
