WebApr 7, 2024 · In utero exposure to diabetes has been shown to contribute to preterm birth, though the underlying biological mechanisms are yet to be fully elucidated. Fetal epigenetic variations established in utero may be a possible pathway. This study aimed to investigate whether in utero exposure to diabetes was associated with a change in newborn DNA … WebOur finding is consistent with documented literature that CpG motifs in the DNA sequence has a direct immune stimulatory effect on B cells. These sequences may cause up-regulation of MHC II, B7 and B7.2 collectively . We can conclude that CpG motifs contain Ф DNA that can activate B cells in mice and rabbits.

WebMar 28, 2010 · Bacterial DNA and synthetic oligodeoxynucleotides (ODNs) that contain unmethylated CpG motifs are strong inducers of immune response in most mammalian organisms. The use of these synthetic CpG motifs in fish, particularly in salmonids and carp, resulted in the modulation of their immune system. However, much less is known in … The CpG sites or CG sites are regions of DNA where a cytosine nucleotide is followed by a guanine nucleotide in the linear sequence of bases along its 5' → 3' direction. CpG sites occur with high frequency in genomic regions called CpG islands (or CG islands). Cytosines in CpG dinucleotides can be methylated to form 5-methylcytosines. E…
CpG motifs are considered pathogen-associated molecular patterns due to their abundance in microbial genomes but their rarity in vertebrate genomes. The CpG PAMP is recognized by the pattern recognition receptor ( PRR ) Toll-Like Receptor 9 ( TLR9 ), which is constitutively expressed only in B … See more CpG oligodeoxynucleotides (or CpG ODN) are short single-stranded synthetic DNA molecules that contain a cytosine triphosphate deoxynucleotide ("C") followed by a guanine triphosphate deoxynucleotide ("G"). The "p" refers … See more Since 1893, it has been recognized that Coley's toxin, a mixture of bacterial cell lysate, has immunostimulatory properties that could reduce the progression of some carcinomas, but it was not until 1983 that Tokunaga et al. specifically identified bacterial DNA as … See more Krieg et al. was the first to describe Class B ODN in 1995. Class B ODN (i.e. ODN 2007) are strong stimulators of human B cell and monocyte maturation. They also stimulate the maturation of pDC but to a lesser extent than Class A ODN and very small amounts of … See more Synthetic CpG ODN differ from microbial DNA in that they have a partially or completely phosphorothioated (PS) backbone instead of the typical phosphodiester … See more One of the first Class A ODN, ODN 2216, was described in 2001 by Krug et al. This class of ODN was distinctly different from the previously described Class B ODN (i.e., ODN 2006) in … See more WebThe protection conferred by antiviral DNA vaccines in fish is known to rely greatly on innate immune responses. Since oligodeoxynucleotides (ODNs) containing unmethylated CpG dinucleotides (CpG motifs) have been shown to induce potential innate immune responses, we have introduced several copies (either two or four) of a fragment containing multiple …
