development of potent new anti-shigella agents for rapid and specific detection and treatment is of great importance. aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. in the present study, we used a systematic evolution of ligands by exponential enrichment (selex) process to select dna aptamers that b...

background & objectives: antisense peptide nucleic acids (pna) that target growth essential genes show potent bactericidal properties without cell lysis. we considered the possibility that whether pna treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to dendritic cells (dcs). dcs are the most potent antigen presenting cells in t...
