Background:

  • Somatic mutation-derived neoantigens are tumor-specific, potentially eliciting potent antitumor T-cell responses.
  • Minimal immune tolerance associated with neoantigens enhances their therapeutic potential in cancer immunotherapy.
  • Neoantigens are primarily identified using bioinformatics approaches, notably whole-exome sequencing.

Purpose of the Study:

  • To review the historical context of neoantigen-driven tumor control.
  • To introduce contemporary methods for neoantigen screening and identification.
  • To discuss the pivotal role of neoantigens in advancing cancer immunotherapies.

Main Methods:

  • Literature review of neoantigen research.
  • Analysis of bioinformatics technologies for neoantigen identification (e.g., whole-exome sequencing).
  • Examination of clinical data from personalized cancer vaccines and adoptive T-cell therapies.

Main Results:

  • Neoantigen-targeted therapies, including personalized vaccines and T-cell therapies, demonstrate promising clinical outcomes.
  • Advancements in bioinformatics have significantly improved the accuracy and efficiency of neoantigen discovery.
  • Neoantigens represent a key frontier in developing effective cancer immunotherapies.

Conclusions:

  • Targeting neoantigens offers a promising strategy for cancer treatment due to their tumor-specific nature and immunogenicity.

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.

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
