Tumor Immunotherapy01:27

Tumor Immunotherapy

639
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.

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

5.2K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

1.1K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Cancer-Critical Genes II: Tumor Suppressor Genes

7.7K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.7K
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...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

12.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Área de la Ciencia:

  • En el campo de la oncología
  • Inmunología
  • Biología del cáncer

Sus antecedentes:

  • El microambiente tumoral es un ecosistema complejo donde las células tumorales y las células inmunes interactúan.
  • La inmunoedición del cáncer describe la interacción dinámica entre el sistema inmunológico y las células cancerosas, que influyen en la evolución del tumor.
  • Este proceso puede conducir a la eliminación del tumor, a un estado latente o a la fuga y progresión del tumor.

Objetivo del estudio:

  • Para comparar la inmunoedición endógena (natural) y la inducida por la terapia.
  • Para esbozar los mecanismos moleculares y celulares que impulsan estas interacciones.
  • Para diferenciar los factores que conducen a la regresión completa del tumor frente al escape y la progresión del tumor.

Principales métodos:

  • Análisis comparativo de las características moleculares y celulares.
  • Revisión de la literatura y los datos existentes sobre la inmunoedición del cáncer.
  • Centrarse en la expresión génica, el metabolismo, la carga mutacional y los cambios de celularidad.

Principales resultados:

  • Las firmas moleculares y celulares distintas caracterizan la inmunorreducción endógena frente a la inducida por la terapia.
  • Las interacciones específicas promueven la regresión del tumor o facilitan el escape del tumor.
  • Los cambios en los componentes del microambiente tumoral son determinantes críticos del resultado.

  • Comprender los matices de la inmunoedición del cáncer es crucial para desarrollar terapias efectivas contra el cáncer.
  • La inmunoedición inducida por la terapia presenta objetivos y desafíos únicos en comparación con los procesos endógenos.
  • La adaptación de estrategias terapéuticas basadas en dinámicas de inmunoedición puede mejorar los resultados de los pacientes.
