The Tumor Microenvironment02:17

The Tumor Microenvironment

8.0K
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Cancer Therapies

10.3K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Area of Science:

  • Oncology
  • Cancer Biology
  • Immunology

Background:

  • The tumor microenvironment (TME) critically affects cancer therapeutic responses and patient prognosis.
  • Drug resistance can arise from soluble factors and cell adhesion within the TME.
  • Components of the TME, including immune cells, can either enhance or impede treatment efficacy.

Purpose of the Study:

  • To explore the multifaceted role of the tumor microenvironment in mediating therapeutic resistance.
  • To identify strategies for overcoming drug resistance by targeting the TME.
  • To highlight the potential of combination therapies that address both tumor cells and their microenvironment.

Main Methods:

  • Review of current literature on TME components and their influence on drug resistance.
  • Analysis of therapeutic strategies targeting extracellular ligand-receptor interactions and signaling pathways.
  • Examination of the role of immune cells and potential for immune reprogramming within the TME.

Main Results:

  • Soluble factors and cell-matrix/stromal cell adhesion contribute to drug resistance.
  • Targeting extracellular interactions and downstream pathways are viable therapeutic approaches.
  • Modulating immune cell activity within the TME offers significant therapeutic potential.

Conclusions:

  • The tumor microenvironment is a crucial determinant of therapeutic success and a key target for overcoming resistance.
  • Strategies involving TME modulation, including immune reprogramming, are essential for improving cancer treatment.
  • Rational drug combinations targeting both tumor cells and the TME represent a promising avenue for enhancing clinical outcomes.
