Hcmva The pp65 peptide is a crucial component derived from the human cytomegalovirus (CMV), specifically its 65 kDa phosphoprotein (pp65).MACSpep CMV pp65 This protein is a significant viral antigen and plays a vital role in CMV's replication, immune evasion, and modulation of the host immune response.Major Tegument Protein pp65 of Human Cytomegalovirus Is ... - NIH Researchers utilize pp65 peptide pools and individual peptides extensively for studying CMV-specific T-cell responses, developing diagnostic tools, and exploring potential therapeutic interventions, such as peptide-based vaccines.
The 65 kDa phosphoprotein (pp65) is one of the most abundant proteins expressed by human cytomegalovirus (HCMV). Its significance in the viral lifecycle and its immunogenicity make pp65 peptides valuable tools in immunology and virology research. These peptides are typically synthesized as 15-mer sequences with an 11-amino acid overlap, covering the entire pp65 protein. This comprehensive coverage ensures that a wide range of epitopes are represented, facilitating robust immune system analysis.STEMCELL Technologies CMV (pp65) Peptide Pool, Size
CMV pp65 peptide pools, such as those available as lyophilized mixtures, are widely used to stimulate CMV-reactive T cells ex vivo. This stimulation is fundamental for assessing cell-mediated immunity against CMV, particularly in immunocompromised individuals, including transplant recipients, where CMV reactivation can lead to severe complications. By analyzing T-cell responses to pp65 peptides, clinicians and researchers can monitor immune status and evaluate the potential efficacy of adoptive T-cell therapiesHCMVA (pp65) Pool of 138 peptides derived from a peptide scan (15mers with 11 aa overlap) through 65 kDa phosphoprotein (pp65) of Human Cytomegalovirus (HCMV)..
Furthermore, specific pp65 peptides, often identified as HLA-restricted epitopes, are of significant interest for vaccine development. For instance, peptides like QYDPVAALF, which is an HLA-A24-restricted CTL epitope, or NLVPMVATV, an HLA-A\*0201-restricted epitope, are being investigated for their therapeutic value in peptide-based vaccines aimed at preventing or treating CMV infections. The ability of these peptides to elicit specific T-cell responses, including CD4+ and CD8+ T cells, makes them potent candidates for stimulating protective immunity.CMV pp65 peptide
Beyond their application in research and therapeutics, understanding the function of the pp65 protein itself provides context for the importance of its derived peptides. The pp65 protein is known to counteract the host's antiviral immune response. When phosphorylated, it can prevent host factors like IRF3 from entering the nucleus, thereby hindering the innate immune signaling pathways that would normally combat viral infectionThe CMV (pp65) Peptide Pool is alyophilized mixture of 138 peptidesfrom the 65 kDa phosphoprotein (pp65) of human cytomegalovirus.. Studying pp65 peptides helps researchers elucidate these intricate mechanisms of viral pathogenesis and immune evasion.
When working with pp65 peptides, several factors are importantCMV pp65 peptide. These include the purity and source of the peptides, their formulation (e.g., lyophilized powder), and their specific sequence and associated HLA restriction. Products like PepTivator CMV pp65 and PepMix Human CMV (pp65) are examples of commercially available peptide pools designed for research applications. Researchers must select peptides or pools that are appropriate for their specific experimental design, whether it involves T-cell stimulation, epitope mapping, or vaccine research.
The pp65 peptide is an indispensable tool in the study of human cytomegalovirus. Its role as a major viral antigen makes it central to understanding CMV pathogenesis, immune responses, and the development of novel diagnostic and therapeutic strategies.The CMV (pp65) Peptide Pool is alyophilized mixture of 138 peptidesfrom the 65 kDa phosphoprotein (pp65) of human cytomegalovirus (CMV; strain AD169). From assessing immune reconstitution in transplant patients to designing peptide-based vaccines, pp65 peptides offer critical insights and potential solutions for managing CMV infections. The ongoing research into specific epitopes and their immunomodulatory functions continues to expand the utility and importance of these viral peptides.
