It has been suggested that gluten consumption is linked to schizophrenia, with this link strengthened through the presence of circulating anti-native gliadin antibodies (AGAs). The human leukocyte antigen (HLA) system is crucial for antigen presentation and antibody secretion but no study has examined the relationship between HLA-II variants and circulating antibodies against gliadin peptides. In this study, HLA-II variants were genotyped in patients with schizophrenia and the relationship between these variants and plasma AGA levels was examined. Although there was no association found, HLA-AGA associations could potentially serve as a marker of gluten sensitivity in patients with schizophrenia.

The polymorphism of HLA class II genes was studied in COVID-19 survivors and vaccinated people. Six allelic variants of DQA1, 10 of DQB1, and 11 of DRB1 were identified. The DQA1*05:01 allele predominated in vaccinated volunteers and the DQA1*02:01, *01:03, and DQB1*06:02-8 alleles predominated in convalescents.

The heritability of susceptibility to tuberculosis (TB) disease has been well recognized. Over 100 genes have been studied as candidates for TB susceptibility, and several variants were identified by genome-wide association studies (GWAS), but few replicate. We established the International Tuberculosis Host Genetics Consortium to perform a multi-ancestry meta-analysis of GWAS, including 14,153 cases and 19,536 controls of African, Asian, and European ancestry.

Article Synopsis
  • Clostridioides difficile infection (CDI) is a major cause of diarrhea in hospitals across North America and Europe, leading to significant health risks.
  • Previous risk factors don't fully explain why some people get CDI while others don't, suggesting a genetic component to susceptibility.
  • A study involving nearly 20,000 participants found that variations in the DRB locus of the MHC (HLA) II region may increase the likelihood of developing CDI, indicating that genetic factors could influence how the body responds to this infection.

Cell surface HLA-I molecules (Face-1) consist of a polypeptide heavy chain (HC) with two groove domains (G domain) and one constant domain (C-domain) as well as a light chain, B2-microglobulin (B2m). However, HCs can also independently emerge unfolded on the cell surface without peptides as B2m-free HC monomers (Face-2), B2m-free HC homodimers (Face 3), and B2m-free HC heterodimers (Face-4). The transport of these HLA variants from ER to the cell surface was confirmed by antiviral antibiotics that arrest the release of newly synthesized proteins from the ER.

Article Synopsis
  • * Researchers used predictive tools to create a heatmap identifying which amino acid changes could lower the binding affinity of the antibody's peptides to HLA II molecules without affecting the antibody's ability to target its specific antigen.
  • * By applying this method to adalimumab, an antibody used for treating inflammatory conditions, the study produced 200 variants with reduced HLA binding scores and identified three that had improved affinity and neutralization capabilities compared to the original adalimumab.
