Vitamin E Scaffolds of pH-Responsive Lipid Nanoparticles as DNA Vaccines in Cancer and Protozoan Infection

open access: yesMolecular Pharmaceutics, 2020
DNA vaccinations are promising strategies for treating diseases that require cellular immunity (i.e., cancer and protozoan infection). Here, we report on the use of a liposomal nanocarrier (lipid nanoparticles (LNPs)) composed of an SS-cleavable and pH-activated lipidlike material (ssPalm) as an in vivo DNA vaccine.

DNA topoisomerases in the unicellular protozoan parasites: Unwinding the mystery

Biochemical Pharmacology, 2022
DNA topoisomerases are a group of enzymes present ubiquitously in all organisms from unicellular protozoan parasites to humans. These enzymes control the topological problems caused by DNA double helix in the cell during nucleic acid metabolism.

Demystifying the potential of inhibitors targeting DNA topoisomerases in unicellular protozoan parasites

Drug Discovery Today, 2023
DNA topoisomerases are a group of enzymes omnipresent in all organisms. They maintain the DNA topology during replication, repair, recombination, and transcription. However, the structure of topoisomerase in protozoan parasites differs significantly from that of human topoisomerases; thus, this enzyme acts as a crucial target in drug development ...

Dna-Protein Interactions at Telomeres in Ciliated Protozoans

Advances in Molecular and Cell Biology, 1988
Publisher Summary This chapter discusses the DNA–protein complexes found at telomeres in the macronuclei of ciliated protozoans, with special attention given to studies in Oxytricha (a hypotrichous ciliate) and Tetrahymena (a holotrichous ciliate). The structure of telomeres has been largely elucidated by studies on macronuclear DNA from ciliated

Stable DNA transfection of the primitive protozoan pathogen Giardia lamblia

Molecular and Biochemical Parasitology, 1998
We have developed a stable DNA transfection vector pRANneo for genetic manipulation of the primitive protozoan Giardia lamblia. pRANneo was constructed by replacing the protein coding region of a Giardia ran gene with a bacterial neomycin phosphotransferase gene (neo). This plasmid was electroporated into G. lamblia, and the transfectants were selected

DNA microarray-based detection and identification of waterborne protozoan pathogens

Journal of Microbiological Methods, 2010
A DNA microarray with 21 oligonucleotide probes was developed to detect most of the common waterborne protozoan pathogens. The DNA microarray accurately identified 3 test protozoa strains based on the small subunit (SSU) rRNA gene sequence. The detection limit was approximately 1x10(3) target genes, or 50 Cryptosporidium parvum oocysts, per assay. As a

DNA Polymerases in Parasitic Protozoans Differ from Host Enzymes

Science, 1980
Analysis of extracts of the bloodstream forms of Trypanosoma brucei showed that both DNA polymerase-α and DNA polymerase-β activities were present. The detection of DNA polymerase-β in T. brucei demonstrates the presence of this enzyme in unicellular organisms.

Stimulation of B lymphocytes, macrophages, and dendritic cells by protozoan DNA

Microbes and Infection, 2002
This review summarizes recent work from our laboratory demonstrating the activation of B lymphocytes, macrophages and dendritic cells by DNA from three different protozoan parasites of cattle and humans that is qualitatively similar to the now well-described effects of CpG-containing bacterial DNA. This novel mechanism of protozoan parasite recognition
