Neoantigendatabase Neoantigen peptides represent a revolutionary frontier in cancer treatment, offering a highly personalized approach to harnessing the body's own immune system to combat tumors.作者：X Chen·2020·被引用次数：98—Syntheticpeptidesare a common platform forneoantigenvaccines. It has been suggested that extending shortpeptidesinto longpeptidescan overcome immune ... These unique peptides, derived from tumor-specific mutations, act as critical biomarkers that allow T cells to recognize and eliminate cancer cellsStudy Details | NCT05269381 | Personalized Neoantigen .... The development and application of neoantigen peptides are rapidly advancing, positioning them as promising targets for novel cancer immunotherapies, particularly in the form of personalized vaccines.
The fundamental concept behind neoantigen peptides lies in their origin: they are newly formed antigens generated by tumor cells due to specific genetic alterations. Unlike normal cellular proteins, these mutated sequences produce peptides that are not typically present in healthy tissues作者：X Tan·2020·被引用次数：75—Neoantigensrepresent a class of shortpeptidesthat are derived from tumor-specific somatic mutations. Notably, they can bind to HLA molecules .... This "non-self" characteristic makes them ideal targets for the immune system. When presented on the surface of cancer cells, these neoantigen peptides can be recognized by T cells, triggering an immune response specifically directed against the tumorA phase I pilot study of personalized neoantigen peptide .... This targeted action minimizes damage to healthy tissues, a significant advantage over traditional cancer treatments.作者：Y Zhang·2025·被引用次数：2—The main objective is to evaluate the anti-tumor efficacy of personalized tumorneoantigen peptidevaccines and assess how different radiation ...
Neoantigens are essentially the products of tumor-specific mutations that are expressed on the cell surface.Giving the personalizedneoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors. Detailed Description. PRIMARY OBJECTIVE: I. To evaluate the safety of personalizedneoantigen peptidevaccine in combination with pembrolizumab in advanced solid cancers ... These mutations can lead to the production of altered proteins, which are then broken down into smaller fragments, or peptidesNeo-antigens are defined as non-selfpeptidesthat are specific for cancer cells and are recognized by the immune system. They are associated with the .... These neoantigen peptides are then displayed by major histocompatibility complex (MHC) molecules, making them visible to T cells. The identification and characterization of these specific peptides are crucial for developing effective immunotherapies.
The process typically begins with sequencing a patient's tumor DNA to identify these unique mutations. Computational algorithms are then used to predict which of these mutations will result in the formation of immunogenic neoantigen peptides. These predicted peptides are synthesized and then used to create personalized vaccines. The goal is to prime the patient's immune system to recognize and attack cancer cells expressing these specific neoantigens.作者：X Tan·2020·被引用次数：75—Neoantigensrepresent a class of shortpeptidesthat are derived from tumor-specific somatic mutations. Notably, they can bind to HLA molecules ...
Neoantigen peptide vaccines are a primary application of this technology.Neoantigen Vaccination These vaccines consist of synthetic peptides that correspond to the identified neoantigens in a patient's tumor. By administering these peptides, the vaccine aims to stimulate a robust T cell response against the cancer1319 First-in-human study of a personalized neoantigen .... This approach is highly personalized, as each vaccine is tailored to the unique mutational profile of an individual's cancer.
Research and clinical trials are exploring various strategies for neoantigen peptide vaccine delivery and composition. Some approaches use short peptides, while others utilize synthetic long peptides (SLPs), which may elicit a more potent and durable immune response. Dendritic cell (DC) vaccines, where dendritic cells are loaded with neoantigen peptides and then administered to the patient, are also being investigated. The combination of neoantigen peptide vaccines with other immunotherapies, such as immune checkpoint inhibitors, is also showing promise in enhancing anti-tumor efficacy.
Despite the immense potential, challenges remain in the field of neoantigen peptide therapy.作者：DA Braun·2025·被引用次数：118—For allpeptides, no pre-existing immune responses were detected, and no clear association was observed between immunogenicity and clonality, ...
