Insights

Tumors trigger immune responses via neoantigens, which are peptides from mutated genes. Identifying these neoantigens is crucial for enhancing cancer immunotherapies like checkpoint blockers and vaccines.

Area of Science:

  • Oncology
  • Immunology
  • Genomics

Background:

  • Tumors elicit adaptive immune responses.
  • Neoantigens, peptides from mutated genes, drive effective T-cell responses.
  • Characterizing neoantigens is vital for cancer immunotherapy.

Purpose of the Study:

  • To review methods for neoantigen quantification.
  • To summarize the neoantigen landscape in solid cancers.
  • To discuss the role of neoantigens in cancer immunotherapy.

Main Methods:

  • Introduction to next-generation sequencing (NGS) for neoantigen quantification.
  • Summary of tools and results for neoantigen landscape characterization.
  • Discussion of emerging aspects like tumor heterogeneity and immunoediting.

Main Results:

  • Methods for quantifying neoantigens using NGS data are presented.
  • The neoantigen landscape in solid cancers is characterized.
  • The importance of neoantigens in various cancer immunotherapies is discussed.

Conclusions:

  • Neoantigen identification and characterization are critical for advancing cancer immunotherapy.
  • Understanding neoantigens improves efficacy of checkpoint blockers, vaccination, and adoptive T-cell transfer.
  • Future prospects involve integrating tumor heterogeneity and immunoediting insights.

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
