ProteomicsImmunogenicity of non-canonical HLA-I tumor ligands identified through proteogenomics
Tumor antigens are central to antitumor immunity. Recent evidence suggests that peptides from non-canonical (nonC) aberrantly translated proteins can be presented on HLA-I by tumor cells. Here, we investigated the presentation and immunogenicity of nonC antigens across different cancer types to bett...

ProteomicsRole for ribosomal quality control in sampling proteins for MHC class I-mediated antigen presentation
Mammalian cells present a fingerprint of their proteome to the adaptive immune system through the display of endogenous peptides on MHC-I complexes. MHC-I peptides originate from protein degradation by the proteasome, suggesting that efficiently-folding, long-lived proteins could evade monitoring. H...

GenomicsComparative Microbial Metagenomic Analysis of Drinking Water Plants and Wastewater Treatment Plants in Istanbul
Wastewater treatment plants (WWTPs) and Drinking water treatment plants (DWTPs) are critical points for public health for persistently remaining microorganisms after treatment may pose a risk. This study aimed to conduct microbial metagenomic analyses on waters from both DWTPs and WWTPs under the Is...

ProteomicsHLA-I peptidomics od Meningioma tissues - Peptide length distribution and multiple specificity in naturally presented HLA-I ligands
HLA-I molecules bind short peptides and present them to CD8+ T cells for TCR recognition. The length of HLA-I ligands typically ranges from 8 to 12 amino acids, but high variability is observed between different alleles. Here we used recent HLA peptidomics data to analyze in an unbiased way peptide ...

ProteomicsCrosslinking mass spectrometry of yeast Pol I pre-initiation complex
In eukaryotic cells, ribosomal RNA is transcribed by RNA polymerase I (Pol I). To initiate transcription, Pol I requires the assembly of a multi-subunit pre-initiation complex (PIC). In yeast, the minimal PIC includes Pol I, the transcription factor Rrn3 and Core Factor (CF) composed of subunits Rrn...

ProteomicsMultimodal HLA-I genotype regulation by human cytomegalovirus US10 and resulting surface patterning
HLA class I (HLA-I) molecules play a central role for both NK and T-cell responses that prevent serious human cytomegalovirus (HCMV) disease. To create opportunities for viral spread, multifaceted HCMV-encoded immunoevasins target HLA-I. Among these, the glycoprotein US10 is so far insufficiently st...

ProteomicsIntegrative MHC-I peptidome quantitation with isobaric tagging mass spectrometry
Despite the appreciation of CD8+ T cell anti-tumor immune responses towards improvement patient outcomes, the MHC-I peptides that facilitate the response are poorly described. Alternatively, whether cancer therapies alter the MHC-I peptide repertoire has not been fully assessed due to the lack of qu...

ProteomicsNative mass spectrometry of peptide-free and partially loaded MHC class I molecules
A disulfide-stabilized MHC class I molecule (HLA-A*02:01(Y84C/A139C), short dsA2) was characterized by native mass spectrometry. dsA2 was shown to be structurally intact in absence of any peptide whereas its wild type form was not. Furthermore, it was observed that the mutation did not disrupt the b...
