Advanced Drug Delivery Reviews
|July 23, 2019
Summary
Cancer immunotherapies show promise, but drug delivery challenges limit effectiveness. Advanced nanomedicines offer a solution for delivering nucleic acid therapies to enhance anti-cancer immune responses.
Area of Science:
- Oncology
- Immunology
- Nanomedicine
Background:
- Cancer immunotherapy, particularly T-cell checkpoint inhibitors, is transforming cancer treatment for advanced diseases like melanoma and non-small cell lung cancer.
- However, many cancers exhibit resistance to current immunotherapies, and clinical translation of novel approaches is hindered by conventional drug delivery limitations.
- Effective immune modulation often necessitates precise, simultaneous activation of multiple signals within specific immune cell populations.
Purpose of the Study:
- To explore the potential of advanced nanomedicines in overcoming drug delivery challenges for novel cancer immunotherapies.
- To highlight the role of nucleic acid therapies in reprogramming the tumor microenvironment towards a pro-immunogenic state.
- To facilitate the clinical translation of promising cancer immunotherapies through improved delivery systems.
Main Methods:
- Review of current advancements in cancer immunotherapy and drug delivery systems.
- Analysis of the requirements for effective immune signaling and intracellular delivery of nucleic acid therapies.
- Evaluation of nanomedicine platforms for engineered delivery of immunotherapeutic agents.
Main Results:
- Conventional drug delivery methods present significant obstacles for effective cancer immunotherapy.
- Nucleic acid therapies demonstrate potential for modulating the tumor microenvironment but require intact intracellular delivery.
- Advanced nanomedicines can be engineered to meet the complex delivery requirements of novel immunotherapies.
Conclusions:
- Nanomedicines are crucial for enabling the clinical translation of next-generation cancer immunotherapies.
- Precise delivery of nucleic acid therapies via nanomedicines can enhance anti-tumor immune responses.
- Overcoming drug delivery limitations is key to realizing the full potential of cancer immunotherapy.

1.8K
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.

00:56Extraction: Advanced Methods
1.1K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

Optimization problems often involve identifying maximum or minimum values under specific constraints. A well-known example is determining the longest horizontal pipe that can be moved around a right-angled corner, where a 3-meter-wide hallway meets a 2-meter-wide hallway. This scenario, common in architectural design and industrial transport, can be understood conceptually through geometric and trigonometric reasoning.To visualize the problem, consider the pipe as a straight line that touches...

01:08Sample Preparation for Analysis: Advanced Techniques
1.3K
Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...
