Anti-EBV P120 Monoclonal antibody

We generated three disease-specific iPSC lines from a Multiple endocrine neoplasia type 1 (MEN1) patient and three control iPSC lines from an unaffected blood relative of the patient using unutilized lymphoblastoid B cell lines (LCLs) as a cell resource. The expression of pluripotency markers, retaining of normal karyotype of chromosome, absence of episomal vectors used for generating the iPSCs and EBV used for generating LCLs, and the potential to differentiate into three germ layers, were confirmed for each iPSC line. These iPSC lines can be useful for construction of the disease models in vitro, and elucidation of the disease mechanisms.

Background Herpesvirusesand bacteria and their interplay have long been believed to play important roles in the pathogenesis of periodontitis, but other microbial entities in the oral environment might also be involved.Anellovirusesare commonly detected in human, including in oral samples. The aim of the present study was to explore the occurrence and co-occurrence ofhuman cytomegalovirus(HCMV),Epstein-Barr virus(EBV), andhuman anelloviruses(HTTVs) in gingival tissue samples collected from participants recruited in Shanghai, China. Methods Gingival tissues were collected from 159 participants (57 with aggressive periodontitis (AP), 59 with chronic periodontitis (CP) and 43 with healthy periodontal status). The presence of HCMV, EBV,torque teno virus(TTV),torque teno mini virus(TTMV) andtorque teno midi virus(TTMDV) DNA was detected by nested-PCR. The virus loads were quantified by real-time PCR. Results The detection rates of EBV, TTV, TTMV and TTMDV were significantly higher in the AP and CP groups compared to the healthy group (allP < 0.01). A statistically significant association was found between EBV, TTV and TTMV virus load and periodontitis (allP < 0.05). Participants infected with EBV showed significantly higher infection rates and higher virus loads of TTV and TTMV than the EBV-negative group (allP < 0.05). The coexistence rates of EBV andanellovirusesand the coexistence of three HTTVs were significantly higher in AP and CP groups (allP < 0.01). Conclusions Collectively, results obtained in this study suggest that HTTVs and the coexistence of EBV and HTTVs in particular, may be associated with periodontitis. Possible mechanisms of the interaction betweenherpesvirusesandanellovirusesin the context of periodontitis require further investigation.
