Resumen
Los macrófagos juegan un papel crítico en el desarrollo y la propagación del cáncer. Dirigirse a poblaciones específicas de macrófagos podría ofrecer nuevas estrategias terapéuticas para el tratamiento del cáncer.
Área de la Ciencia:
- Oncología e Inmunología.
Sus antecedentes:
- Los macrófagos son células inmunes clave implicadas en el inicio y la progresión del cáncer.
- Contribuyen a un entorno inflamatorio pro-tumorigénico durante el inicio del tumor.
- Los macrófagos también promueven la angiogénesis, la invasión y la supresión inmune en tumores establecidos.
Objetivo del estudio:
- Aclarar las múltiples funciones de los macrófagos a lo largo del desarrollo del cáncer.
- Para resaltar la participación de los macrófagos en la metástasis.
- Para identificar las subpoblaciones de macrófagos como posibles objetivos terapéuticos.
Principales métodos:
- Revisión de la evidencia clínica y experimental.
- Análisis de las funciones de los macrófagos en las diferentes etapas del cáncer (inicio, progresión, metástasis).
Principales resultados:
- Los macrófagos crean condiciones inflamatorias mutagénicas durante la iniciación del tumor.
- Estimulan la angiogénesis, mejoran la migración y invasión de las células tumorales y suprimen la inmunidad antitumoral.
- Distintas subpoblaciones de macrófagos facilitan la extravasación de las células tumorales y el crecimiento en sitios metastásicos.
Conclusiones:
- Los macrófagos son parte integral de todas las etapas del cáncer, desde la iniciación hasta la metástasis.
- Dirigirse a subpoblaciones especializadas de macrófagos presenta una vía prometedora para nuevas terapias contra el cáncer.

02:07Tumor Progression
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...

02:17The Tumor Microenvironment
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...

02:30Metastasis
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...

02:53Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
