The Tumor Microenvironment02:17

The Tumor Microenvironment

6.8K
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...

Metastasis02:30

Metastasis

5.7K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Immunotherapy01:27

Tumor Immunotherapy

659
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.

Tumor Progression02:07

Tumor Progression

6.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Área de la Ciencia:

  • En el campo de la oncología
  • Microbiología
  • Inmunología

Sus antecedentes:

  • Los tumores son cada vez más reconocidos como ecosistemas complejos que contienen microbios, desafiando el paradigma del tumor estéril.
  • Las bacterias asociadas al tumor (TAB) se involucran en una intrincada conversación cruzada con el microambiente tumoral (TME).
  • Esta interacción influye en las características críticas del cáncer, incluyendo la inmunidad, la metástasis y la eficacia terapéutica.

Objetivo del estudio:

  • Resumir los conocimientos actuales sobre las bacterias asociadas al tumor (TAB) y su papel en el cáncer.
  • Resaltar las cuestiones clave relativas a los orígenes y las funciones de TAB dentro de la TME.
