Summary: By studying the proteomics of EGFR TKI-resistant lung adenocarcinoma cells, we have identified a reduction in the HLA class I-presented immunopeptidome, downregulation of antigen presentation core complex and immunoproteasome, as well as differential alterations in certain components of the autophagy pathway. These findings reveal potential immune evasion mechanisms in osimertinib-resistant lung adenocarcinoma.

Summary: T cell-mediated immune therapies show promise in treating various malignancies, but only a small fraction of patients respond to treatment. Understanding the lack of responses and identifying predictive biomarkers is crucial. CRC is a heterogeneous disease, and the loss of HLA-I in CRC is associated with immune evasion and metastasis.

Summary: The loss of MHC-I in DLBCL is associated with somatic inactivation of HLA-I loci and has a significant impact on neoantigen and mutational burden. There is a multistep process of HLA-I loss in DLBCL development involving both germline and somatic events.

Summary: Loss of MHC I antigen presentation is common in many cancers, which may impair immune responses and affect the efficacy of immunotherapy. Studies have discussed underlying mechanisms through which some cancers evade immune killing by shutting down the MHC I pathway, and proposed potential strategies to overcome this limitation.

Summary: HLA class I glycoproteins play a crucial role in driving immune responses by presenting antigens, but tumors and pathogens often exploit this process for immune evasion. Through genome-wide screens, it was discovered that the cell surface glycosphingolipid repertoire determines effective HLA-I antigen presentation. Inhibition of GSL synthesis may represent a potential therapeutic target in cancer, infection, and autoimmunity, offering a promising avenue for immune modulation.

Summary: The study revealed that HLA class I expression is significantly upregulated in thyroid tissue from GD patients, along with a higher presence of enterovirus protein. Co-localization of STAT1 with HLA class I and PKR with VP1 within thyroid cells suggests an antiviral tissue response.

Summary: A subset of colorectal cancers with mismatch repair deficiency are sensitive to immune checkpoint inhibitors, but some patients show primary resistance or develop acquired resistance. Changes in the Wnt and JAK-STAT signaling pathways, as well as alterations in the antigen presentation machinery, are associated with resistance to CPIs in these patients. Understanding the mechanistic basis of immune evasion in CRC provides rationale for innovative strategies to increase the subset of patients benefiting from CPIs.

Summary: The study found that immunodominant HIV epitopes increase surface stabilization of HLA class-I molecules compared to subdominant epitopes, and HLA class-I-peptide stability is strongly correlated with overall immunodominance hierarchies. Additionally, HLA alleles associated with HIV protection are preferentially stabilized by epitopes derived from topologically important viral regions.

Summary: The extreme polymorphisms of HLA class I proteins enable diverse peptide presentation, and the endo-lysosomes in moDCs play a role in the presentation of HLA class I molecules. HLA-B allotypes display varying responses to disruption of the endo-lysosomal pH, with HLA-B*08:01 being more resistant and HLA-B*35:01 being more sensitive. The degree of endo-lysosomal assembly dictates constitutive HLA class I expression and affects the efficiency of cross-presentation.

Summary: The presentation of antigenic peptides by MHC class I and class II molecules is crucial for activating the adaptive immune system, with CIITA and NLRC5 serving as the major transcriptional activators of MHC class II and class I gene expression. Recent advances in understanding the role of NLRC5 in infectious diseases and cancer have shed light on its biological significance and mechanism in MHC class I expression.

Summary: The study reveals a new transcriptional mechanism by which EBV encoded EBNA2 down-regulates HLA class II gene expression, impacting T-cell recognition of infected cells. EBNA2 competes with CIITA binding, leading to CIITA transcriptional down-regulation and subsequent HLA-II gene expression attenuation. This indirect regulation is proposed to be due to enhancer competition at neighboring chromosome domains.

Summary: In this study of 651 colon cancer patients, it was found that beta 4 expression was not associated with worse clinical prognosis, but decreased with advanced pathological tumor stage. Future studies should further determine whether loss of beta 4 expression promotes invasive characteristics of colon cancer cells.

Summary: DNA mismatch repair-deficient (MMR-d) cancers with inactivation of beta 2-microglobulin (B2M) retained responsiveness to immune checkpoint blockade (ICB) and showed increased infiltration by gamma delta T cells expressing PD-1 and high reactivity to HLA-class-I-negative tumour cells. Dual PD-1 and CTLA-4 blockade increased the frequency of gamma delta T cells in B2M-deficient cancers, suggesting the potential of gamma delta T cells in cancer immunotherapy.

Summary: This study aimed to evaluate the health outcomes of children born after embryo vitrification compared to children born after fresh embryo transfer. The results showed that children born after embryo vitrification had higher birthweight, height, and head circumference than children born after fresh embryo transfer. However, there were no significant differences in growth and weight gain between the two groups during infancy and early childhood.

Summary: The lack of multi-omics cancer datasets with extensive follow-up information hinders the identification of accurate biomarkers of clinical outcome. In this cohort study, comprehensive genomic analyses were performed on fresh-frozen samples from 348 patients with primary colon cancer. The study revealed a gene expression signature called Immunologic Constant of Rejection that outperformed conventional prognostic molecular biomarkers. Additionally, a favorable outcome was associated with a microbiome signature driven by Ruminococcus bromii.

Summary: This study reveals the changes in immune subsets in the developing human foetal intestine, showing the sequential appearance of different types of immune cells between gestational weeks 14 and 22. The presence of immune subset-committed cells capable of local proliferation suggests their important role in the development of organized immune structures and potential influence on microbial colonization after birth.

Summary: MCM8 and MCM9 are recently discovered minichromosome maintenance proteins that play roles in various DNA-related processes and diseases, including DNA replication, meiosis, homologous recombination, and mismatch repair. Variants of MCM8/MCM9 may predispose carriers to infertility and cancer and should be included in relevant diagnostic testing.

Summary: We present a case of a 2.5-year-old boy with a pure androgen-secreting adrenocortical tumor, characterized by penile enlargement, pubic hair, frequent erections, and rapid linear growth. The diagnosis was confirmed through laboratory tests, medical imaging, and histology. Additionally, genetic testing revealed a pathogenic germline variant in the TP53 gene, confirming an underlying Li-Fraumeni syndrome.

Summary: Immune checkpoint therapy (ICT) has the potential to eliminate cancer, but the underlying mechanisms determining its effectiveness are not fully understood. By using high-dimensional single-cell profiling, this study investigates if the T cell landscape in peripheral blood can predict responses to combinatorial targeting of the OX40 costimulatory and PD-1 inhibitory pathways. The findings reveal dynamic activation states of therapy-responsive T cells and emphasize the importance of NK cell receptors and chemokine receptors in therapy-induced anti-tumor immunity.

Summary: BAP1 is a tumor suppressor gene associated with predisposition to multiple tumors. BAP1 carriers have up to 85% lifetime risk of developing at least one BAP1-associated tumor, although current risk estimates may be overestimated. European recommendations for surveillance of BAP1 carriers have not been published, but collaboration is underway to develop guidelines for harmonizing surveillance programs in Europe.
