Insights

Cancer vaccines stimulate the immune system to fight tumors by targeting tumor-associated antigens. These antigens are present on cancer cells and sometimes normal tissues, prompting an antitumor response.

Area of Science:

  • Immunology
  • Oncology
  • Vaccinology

Background:

  • Immune system targets cancer cells via antigens, but many antigens are shared with normal tissues.
  • Tumor-associated antigens arise from mutated genes, aberrant gene expression, or viral proteins.
  • Cancer vaccines aim to harness the immune system for cancer treatment.

Purpose of the Study:

  • To explore the role of tumor-associated antigens in cancer immunotherapy.
  • To understand how vaccines can stimulate an antitumor immune response.
  • To investigate the specificity of cancer antigens.

Main Methods:

  • Review of immunological principles in cancer therapy.
  • Analysis of antigen presentation in tumor microenvironments.
  • Discussion of vaccine strategies for cancer treatment.

Main Results:

  • Identified shared antigens between tumor and normal cells as key targets.
  • Highlighted the potential of vaccines to elicit specific antitumor immunity.
  • Emphasized the importance of antigen overexpression on tumor cells.

Conclusions:

  • Vaccines represent a promising active immunotherapy for cancer.
  • Targeting tumor-associated antigens can stimulate the intrinsic antitumor immune response.
  • Overexpression of antigens on tumor cells is crucial for vaccine efficacy.

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
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.
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
