The increasing interest in methylation patterns of mammalian DNA demands a simple and reliable method to clearly differentiate between cytosine (C) and 5-methylcytosine (5-MeC) within a specific DNA region. The simplest and most commonly used approach is the analysis with restriction endonucleases exhibiting different methylation sensitivities, like the MspI/HpaII pair of isoschizomeric enzymes...

an inoculation of virulent leishmania major is known as leishmanization (lz) which is proven to be the most effective control measure against cutaneous leishmaniasis (cl). however, using lz is restricted due to various side effects such as uncontrolled lesion development. in the present research, the efficacy of cationic nanoliposomes containing cpg oligodeoxynucleotides (cpg odn) as an improve...

Background: Dendritic cells (DCs) are professional antigen presenting cells that have an important role in the initiation of immune response. The use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. Objective: In this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and CpG oligonucleotides in inducing d...

Treatment with an oligodeoxynucleotide (ODN) containing CPG motifs (CpG ODN 7909) was found to protect BALB/c mice from lung infection or death after aerosol challenge with Burkholderia mallei. Protection was associated with enhanced levels of gamma interferon (IFN-gamma)-inducible protein 10, interleukin-12 (IL-12), IFN-gamma, and IL-6. Preexposure therapy with CpG ODNs may protect victims of ...

BACKGROUND Bacterial DNA containing motifs of unmethylated CpG dinucleotides (CpG-ODN) initiate an innate immune response mediated by the pattern recognition receptor Toll-like receptor 9 (TLR9). This leads in particular to the expression of proinflammatory mediators such as tumor necrosis factor (TNF-alpha) and interleukin-1beta (IL-1beta). TLR9 is expressed in human and murine pulmonary tissu...

Multiplex bisulfite-PCR sequencing is a convenient and scalable method for the quantitative determination of the methylation state of target DNA regions. A challenge of this application is the presence of CpGs in the same region where primers are being placed. A common solution to the presence of CpGs within a primer-binding region is to substitute a base degeneracy at the cytosine position. Ho...
