Regulatory T cells: A target in anticancer immunotherapy.
Nihon Rinsho. Japanese Journal of Clinical Medicine
|December 19, 2018
Summary
Regulatory T cells (Tregs) abundant in tumors suppress anti-tumor immunity. Targeting Tregs is key for effective cancer immunotherapy, requiring understanding their tumor-promoting mechanisms.
Area of Science:
- Immunology
- Oncology
Background:
- Regulatory T cells (Tregs) expressing Foxp3 are vital for immune tolerance and preventing autoimmunity.
- Abundant Tregs in tumor tissues suppress anti-tumor immunity, promoting cancer progression.
- Distinct Treg subsets exhibit varied roles and prognostic impacts in cancer.
Purpose of the Study:
- Investigate the role of Tregs in tumor progression.
- Explore strategies to overcome Treg-mediated immune suppression in cancer.
- Understand Treg abundance mechanisms for improved immunotherapy.
Main Methods:
- Analysis of Treg populations in tumor microenvironments.
- Evaluation of Treg suppressive functions.
- Assessment of Treg subset heterogeneity and function.
Main Results:
- Tregs significantly suppress anti-tumor immune responses.
- Specific Treg subsets demonstrate distinct contributions to cancer prognosis.
- Mechanisms driving Treg accumulation in tumors identified.
Conclusions:
- Targeting Tregs is a promising strategy for enhancing anti-tumor immunity.
- Understanding Treg biology is critical for developing effective cancer immunotherapies.
- Selective Treg reduction or functional attenuation can improve therapeutic outcomes.

02:02Cis-regulatory Sequences
11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

01:27Tumor Immunotherapy
1.9K
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.

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

01:22Target Cell Response to Hormones
5.7K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

01:03Drug Control Governance: Regulatory Bodies and Their Impact
556
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...
