Summary
Cancer therapy resistance stems from tumor microenvironment heterogeneity. Targeting metabolic modifications like glycosylation and palmitoylation in inflammation offers new immunotherapy strategies.
Area of Science:
- Oncology
- Immunology
- Metabolic pathways
Background:
- Cancer immunotherapy has advanced significantly, but tumor microenvironment heterogeneity leads to therapy resistance.
- Metabolic dysfunction in tumor and stromal cells is a hallmark of cancer, altering protein homeostasis.
- Posttranslational modifications, including glycosylation and palmitoylation, affect protein function and are implicated in inflammation and tumorigenesis.
Purpose of the Study:
- To review recent advances in metabolic modifications impacting cancer immunotherapy.
- To elucidate the mechanisms by which glycosylation and palmitoylation regulate innate immunity and inflammation.
- To discuss novel immunotherapy strategies targeting metabolic modifications for improved cancer treatment.
Main Methods:
- Literature review of recent studies on metabolic modifications in cancer.
- Analysis of mechanisms linking glycosylation and palmitoylation to immune regulation.
- Exploration of therapeutic strategies targeting metabolic pathways in cancer.
Main Results:
- Metabolic dysfunction reprograms cellular homeostasis, influencing protein modifications.
- Glycosylation and palmitoylation are key posttranslational modifications affecting protein localization, stability, and function.
- These modifications play critical roles in inflammation, tumorigenesis, and cancer progression.
Conclusions:
- Targeting metabolic modifications in immune checkpoints and inflammation presents a promising therapeutic avenue.
- Understanding these mechanisms can lead to improved immunotherapy and targeted-therapy responses.
- This approach holds potential for more precise and individualized cancer treatment.

741
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.

02:17The Tumor Microenvironment
7.0K
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...

01:28Inflammatory Response
12.2K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

02:53Adaptive Mechanisms in Cancer Cells
6.0K
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,...

03:03mTOR Signaling and Cancer Progression
3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
