It was a wonderful collaboration with Thomas Vogl Medical University of Vienna and @sashazhernakova.bsky.social at @rug.nl I am also grateful to my research group. immunoinfo.hu

Moreover, HLA variants with broader peptide-binding specificity are also associated with stronger antibody responses following influenza vaccination. Check out our article to learn more!

Our results suggest that the answer is yes: HLA variants capable of binding a broader range of peptide sequences may provide broader protection against common infections, whereas more selective variants may confer protection against specific pathogens.

Individuals can carry different variants of HLA genes. Some HLA variants bind a broad range of peptide sequences, whereas others are more selective. Is this variation associated with susceptibility to infection? www.nature.com/articles/s41...

Human leukocyte antigen class II (HLA-II) are involved in the presentation of peptides to helper T cells which guide in the B cell response and antibody production. Here Magyari et al, show that HLA-I...

Five mutational “fingerprints” could help predict how visible tumours are to the immune system
Researchers from the HUN-REN Szeged Biological Research Centre and HCEMM have just published a new study suggesting that it’s not simply the number of tumour mutations that matters for immunothe...

9/ Takeaway: Protein-level mutation patterns provide a complementary lens to DNA mutational signatures—linking mutagenesis + repair defects to peptide properties, immune contexture, and therapy response.

8/ But there’s nuance inside AAS4: Among AAS4-driven tumors, specific HLA variants are enriched in immune-hot cases. So antigen presentation genetics may modulate whether an AAS4 tumor ends up “cold” vs “hot.”

7/ One signature stood out clinically: AAS4. AAS4 is associated with predominantly immune-cold tumors, poor prognosis, and limited response to immune checkpoint blockade.

6/ That biophysical bias matters for immunology. By shaping the properties of mutated peptides, AASs can influence neopeptide immunogenicity → and, downstream, the tumor immune microenvironment.

5/ Next: not all amino acid substitutions are equal. Different AASs preferentially generate amino acids with distinct biophysical properties (think charge, polarity, size).

Máté Manczinger @matemanc.bsky.social · 03/02/2026
4/ Why does that matter? Because it suggests the protein-level consequence can converge even when the DNA-level cause differs.

3/ Importantly, these AASs aren’t a 1:1 readout of any single DNA mutational process. The same AAS can be produced by multiple, largely unrelated exogenous + endogenous mutagenic processes.

2/ ~82% of tumor samples are dominated by a single AAS. So despite massive heterogeneity, most cancers have one main “protein-mutation style.”

1/ Cancer mutations look chaotic—different tumors, different genes, different DNA changes. But at the protein level, we found surprising order. Introducing amino acid substitution signatures (AASs): 5 recurrent patterns that repeatedly show up across cancers.
