The EBV (EBNA-3a) Peptide Pool from peptides&elephants is designed for in vitro T cell stimulation and epitope analysis in research on Epstein-Barr virus (EBV, HHV-4). This pool contains 234 synthetic 15-mer peptides, overlapping by 11 amino acids, and spans the complete sequence of EBNA-3a (Epstein-Barr nuclear antigen 3a; UniProt ID: P12977). Each unit enables the stimulation of up to 2.5 × 10⁸ peripheral blood mononuclear cells (PBMCs) and is ideal for use in ELISpot, intracellular cytokine staining (ICS), and flow cytometry-based T cell assays.
Scientific Background
EBV is a ubiquitous herpesvirus that infects more than 90% of the global population. It is the causative agent of infectious mononucleosis and is closely associated with several B cell malignancies, including post-transplant lymphoproliferative disease (PTLD), diffuse large B cell lymphoma (DLBCL), Burkitt lymphoma, and Hodgkin lymphoma.
During latency, EBV can enter different gene expression programs. Latency type III, in which all nine latent proteins are expressed, is the only form capable of transforming B cells in vitro, resulting in lymphoblastoid cell lines (LCLs). Among these latency proteins, EBNA-3a plays a supportive but non-essential role in B cell transformation:
- EBV mutants lacking EBNA-3a can still transform B cells, but with significantly reduced efficiency.
- EBNA-3a–deficient LCLs proliferate more slowly and show increased apoptosis compared to wild-type virus–derived LCLs.
- EBNA-3a appears to regulate a subset of cellular genes, some of which overlap with those regulated by EBNA2. The two proteins can act antagonistically or cooperatively to control gene expression.
These findings position EBNA-3a as a key modulator of B cell proliferation and survival during EBV latency, and as a relevant CD8⁺ T cell target in both basic immunological studies and translational research.
