Tumor Immunotherapy

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-Critical Genes II: Tumor Suppressor Genes

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Adaptive Mechanisms in Cancer Cells

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,...

Tumor Progression

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...

Summary

The immune system normally eliminates threats and remembers them. However, the body may not develop a strong memory response against malignant cells, potentially due to their "sweet" nature.

Area of Science:

Immunology
Oncology
Cellular Biology

Background:

The immune system comprises natural and educated components for identifying and eliminating pathogens, waste, and abnormal cells.
This dual system ensures immediate threat removal and establishes immunological memory for future encounters.
While effective against infections, the immune response to malignant cells appears limited, primarily engaging innate immunity.

Purpose of the Study:

To investigate why the adaptive immune system may fail to generate a robust memory response against malignant cells.
To explore the hypothesis that tumor-specific antibodies are predominantly associated with natural immunity.
To elucidate the mechanisms underlying the limited immune memory formation in cancer.

Main Methods:

Review of existing literature on natural and educated immunity.

Analysis of humoral immune responses in cancer.

Examination of tumor-specific antibody characteristics.

Main Results:

Tumor-specific antibodies detected so far primarily belong to the natural immunity repertoire.
The humoral immune response against malignant cells appears restricted and may not effectively induce adaptive memory.
Malignant cells may possess properties that hinder the development of a long-lasting immune memory.

Conclusions:

The immune system's failure to generate memory against cancer may be linked to the nature of malignant cells, described metaphorically as 'too sweet'.
Further research is needed to fully understand the immunological evasion strategies employed by tumors.
Understanding these mechanisms could pave the way for novel cancer immunotherapies that enhance anti-tumor memory.
