Mass tag-assisted identification of naturally processed HLA class II-presented meningococcal peptides recognized by CD4+ T lymphocytes.
The meningococcal class I outer membrane protein porin A plays an important role in the development of T cell-dependent protective immunity against meningococcal serogroup B infection and is therefore a major component of candidate meningococcal vaccines. T cell epitopes from porin A are poorly characterized because of weak in vitro memory T cell responses against purified Ag and strain variati...
متن کاملNaturally processed and presented epitopes of the islet cell autoantigen IA-2 eluted from HLA-DR4.
During immune responses, antigen-presenting cells (APCs) process antigens and present peptide epitopes complexed with human leukocyte antigen (HLA) molecules. CD4 cells recognize these naturally processed and presented epitopes (NPPEs) bound to HLA class II molecules. Epitope identification is important for developing diagnostic and therapeutic tools for immune-mediated diseases and providing i...
متن کاملPhosphorylated Peptides Are Naturally Processed and Presented by Major Histocompatibility Complex Class I Molecules in Vivo
Posttranslational modification of peptide antigens has been shown to alter the ability of T cells to recognize major histocompatibility complex (MHC) class I-restricted peptides. However, the existence and origin of naturally processed phosphorylated peptides presented by MHC class I molecules have not been explored. By using mass spectrometry, significant numbers of naturally processed phospho...
متن کاملIdentification and characterization of novel, naturally processed measles virus class II HLA-DRB1 peptides.
Previously, we identified a naturally processed and presented measles virus (MV) 19-amino-acid peptide, ASDVETAEGGEIHELLRLQ (MV-P), derived from the phosphoprotein and eluted from the human leukocyte antigen (HLA) class II molecule by using mass spectrometry. We report here the identification of a 14-amino-acid peptide, SAGKVSSTLASELG, derived from the MV nucleoprotein (MV-N) bound to HLA-DRB1*...
متن کاملSpecificity and promiscuity among naturally processed peptides bound to HLA-DR alleles
Naturally processed peptides were acid extracted from immunoaffinity-purified HLA-DR2, DR3, DR4, DR7, and DR8. Using the complementary techniques of mass spectrometry and Edman microsequencing, > 200 unique peptide masses were identified from each allele, ranging from 1,200 to 4,000 daltons (10-34 residues in length), and a total of 201 peptide sequences were obtained. These peptides were deriv...
