Synthetic oligodeoxynucleotides containing unmethylated CpG motifs (CpG) stimulate innate immune responses. Phosphoinositide 3-kinase (PI3K) has been implicated in CpG-induced immune activation; however, its precise role has not yet been clarified. CpG-induced production of IL-10 was dramatically increased in macrophages deficient in PI3Kγ (p110γ(-/-)). By contrast, LPS-induced production of IL...

Synthetic oligodeoxynucleotides expressing CpG motifs (CpG-ODN) are a Toll-like receptor 9 (TLR9) agonist that can enhance the antitumor activity of DNA-damaging chemotherapy and radiation therapy in preclinical mouse models. We hypothesized that the success of these combinations is related to the ability of CpG-ODN to modulate genes involved in DNA repair. We conducted an in silico analysis of...

To determine if deoxycytidyl-deoxyguanosine oligonucleotides (CpG ODN) can be used effectively as nonspecific inducers of innate immune defenses for preventative or therapeutic interventions in infectious disease models for nonhuman primates, the present study evaluated the response of rhesus monkey peripheral blood mononuclear cells to three different synthetic CpG ODN classes by defining the ...

Abstract Introduction: LAM is a slow growing, metastasizing neoplasm affecting women of reproductive age, marked by abnormal growth smooth muscle-like cells leading to cystic lung destruction. has hallmarks cancer, like expression immune checkpoint receptors. Effective cancer therapies promote robust T cell responses through activated dendritic (DCs). Anti-cancer strategies, toll receptor (TLR)...

Plasmacytoid dendritic cells (PDC) represent a highly specialized immune cell subset that produces large quantities of the anti-viral cytokines type I interferons (IFN-alpha and IFN-beta) upon viral infection. PDC employ a member of the family of toll-like receptors, TLR9, to detect CpG motifs (unmethylated CG dinucleotides in certain base context) present in viral DNA. A certain group of CpG m...

CpG-island margins and non-island-CpG sites round the transcription start sites of CpG-island-positive and -negative genes are methylated to various degrees in a tissue-specific manner. These methylation-variable CpG sites were analyzed to delineate a relationship between the methylation and transcription of the tissue-specific genes. The level of tissue-specific transcription was estimated by ...

Ontology-based modeling of Clinical Practice Guidelines (CPG) is a well-established approach to computerize CPG for execution in clinical decision support systems. Many CPG computerization approaches use the Web Ontology Language (OWL) to represent the CPG’s knowledge, but they do not exploit its reasoning services to execute the CPG. In this paper, we present our CPG execution approach that le...

OBJECTIVES/GOALS: COPD is a progressive airways disease that results in death or disability. There poor uptake of clinical guidelines (CPG) to manage and studies bridge this implementation gap have shown inconsistent results. Using science principles we aim understand COPD-CPG determinants from providers’perspective. METHODS/STUDY POPULATION: The study being conducted ten VA Primary Care Clinic...
