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...

Area of Science:

  • Immunology
  • Oncology
  • Biotechnology

Background:

  • Developing effective cancer immunotherapies requires a detailed understanding of the tumor immune microenvironment.
  • Previous research has highlighted the heterogeneity of immune infiltrates across different cancer types.

Purpose of the Study:

  • To investigate the immune cell composition in lung adenocarcinoma and clear cell renal cell carcinoma.
  • To provide insights into the immune landscape that could inform future immunotherapy strategies.

Main Methods:

  • Mass cytometry (cytometry by time-of-flight) was employed to perform high-dimensional single-cell analysis.
  • Immune infiltrates within tumor tissues were meticulously characterized.

Main Results:

  • Detailed profiling of immune cell populations and their spatial distribution in lung adenocarcinoma.
  • Comprehensive analysis of immune infiltrates in clear cell renal cell carcinoma, revealing distinct immune signatures.

Conclusions:

  • Mass cytometry offers a powerful approach to dissecting complex immune infiltrates in human cancers.
  • These findings contribute to a deeper understanding of cancer immunity, paving the way for improved immunotherapeutic interventions.
