Summary: Cancer-testis antigen CT23 is an immunogenic tumor-associated antigen that is closely related to tumor cell viability and metastasis. The candidate peptide P7 showed the highest binding affinity and stimulated activation and proliferation of CD8+ T cells. This peptide induced specific cytotoxic effects on tumor cells and T2 cells. Therefore, CT23 peptide P7 holds potential as a therapeutic target for cancer treatment.

Summary: Our research identified the HLA-A*0201-restricted cytotoxic T-lymphocyte (CTL) epitope MLAA-34(236-244) as having strong binding affinity and inducing significant interferon-gamma production. CTLs targeting this epitope showed potent cytotoxicity against leukemia cells and inhibited tumor growth. Additionally, immunization with the MLAA-34(236-244) peptide vaccine resulted in elevated levels of interferon-gamma and enhanced survival in mouse models of leukemia.

Summary: The role of vaccination has been expanded in the management of HER2/neu-positive breast cancer, with effective vaccines needing to induce both humoral and cellular immune responses. A multi-epitope peptide vaccine including B-cell epitope was found to be superior in inhibiting tumor growth and prolonging survival in animal models. This highlights the importance of incorporating B-cell epitopes in cancer vaccine design.

Summary: This study investigated the prognostic role of HER-2/neu-specific T cell immunity in prostate cancer patients. The results showed that high frequencies of HER-2/neu-specific CD8+ T lymphocytes were associated with better progression-free survival and lower levels of TGF-beta and IL-8 in patients receiving standard treatment.

Summary: Combining immune checkpoint inhibitor (ICI) with vaccination strategies can enhance antitumor immunity and improve therapeutic response in triple negative breast cancer (TNBC) patients. Through the analysis of tumor samples, potential immunogenic neoantigens (neoAgs) suitable as vaccines were identified and shown to induce T-cell responses, suggesting their potential application in therapeutic vaccines.

Summary: Current pre-transplantation routine matching based on serum anti-HLA antibodies quantification is not always effective in predicting graft outcomes. In this study, machine learning algorithms were used to analyze anti-HLA-II loci responses and identify specific HLA epitopes associated with antibody responses. These findings provide insights into interlocus cross-reactivity and suggest a novel strategy for optimal donor selection.

Summary: The flexibility of antibody sequences was evaluated to reduce the affinity of corresponding peptides for HLA II molecules and maintain antibody binding to its target. Permissive substitutions were identified through T-cell epitope prediction tools and deep mutational scanning to reduce affinity for HLA II molecules and preserve binding to the target. This approach identified mutants with lower HLA binding scores and higher affinity for TNF-α and neutralization ability compared to adalimumab. The study also highlights the permissiveness of antibody sequences in terms of functionality and predicted T cell epitopes.

Summary: Giardiasis is a common gastrointestinal infection worldwide, mainly in developing countries caused by the Giardia lamblia parasite. The disease primarily affects children and immunocompromised individuals, leading to symptoms such as diarrhea, dehydration, and abdominal pain. Understanding the host-Giardia interactions and identifying parasite antigens that activate the host immune system are essential for developing an effective vaccine against giardiasis.

Summary: This study introduces a high-throughput epitope identification system that combines T cell-secreted cytokines capture, cell sorting, and next-generation sequencing to identify new class I- and class II-restricted epitopes. The technology successfully validated known viral, neoepitope, and autoimmune epitope-specific TCR targets, as well as discovered new epitopes encoded by the human cytomegalovirus genome. This cytokine capture-based assay enables pooled screening of thousands of encoded peptides for epitope discovery and may lead to identification of HLA-epitope-TCR complexes relevant to disease control, etiology, or treatment.

Summary: A series of novel biphenyl-based scaffold derivatives were identified as selective HDAC6 inhibitors, exhibiting good inhibitory activity and selectivity. Compound C10, in particular, showed potent HDAC inhibition, anti-proliferative and anti-migration effects on cancer cells, and significant antitumor efficacy in a mouse colon cancer model.

Summary: The study identified a rare neoantigen in mismatch repair-deficient colorectal cancer tissue, which was associated with abundant tumor-infiltrating lymphocytes and an inflamed gene expression status. CD8(+) TILs predominantly recognized the detected neoantigen and exhibited functional and specific responses.

Summary: This study identified and characterized potential CTL target epitopes of bovine ephemeral fever virus (BEFV) using immuno-informatics tools. Four potential CTL epitopes were identified for the G protein of BEFV. The 3D structure of a multi-epitope was predicted and validated. This study provides important information for immune response and vaccine development against BEFV.

Summary: In this study, 25 HLA-A0201 restricted GPC3 epitopes were predicted and 5 were identified as real-world epitopes for specific CD8(+) T cell activation. These epitopes were further confirmed to induce robust CD8(+) T cell responses and cytotoxicity targeting HepG2 cells, providing potential for the development of T cell epitope vaccines and evaluation of GPC3 specific T cell responses.

Summary: A series of diaryl heterocyclic analogues were synthesized as tubulin polymerization inhibitors. Compound 6y exhibited the highest antiproliferative activity against HCT-116 colon cancer cells and effectively inhibited tubulin polymerization in vitro. It also showed high metabolic stability on human liver microsomes and suppressed tumor growth in a HCT-116 mouse colon model without toxicity. These results suggest that 6y represents a new class of tubulin inhibitors worthy of further investigation.

Summary: Radiotherapy not only directly affects cancer cells, but also mediates indirect antitumor effects through the immune system. Investigations into the mechanisms underlying the interaction between radiotherapy and the immune system have uncovered ways to enhance the antitumor efficacy of radiotherapy. Radiotherapy can also be combined with immunotherapy to stimulate antitumor immunity.
