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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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...

Cancer Vaccines

509
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

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...

Cancer Therapies

7.9K
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...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

1.9K
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...

Resumen
Este resumen es generado por máquina.

El punto de control inmune TIGIT inhibe la actividad de las células T y NK. Se están explorando nuevas terapias combinadas y enfoques alternativos debido a las limitaciones con la monoterapia de anticuerpos anti-TIGIT en ensayos clínicos.

Área de la Ciencia:

  • Inmunología
  • Biología del cáncer
  • Desarrollo de drogas

Sus antecedentes:

  • TIGIT (inmunorreceptor de células T con dominios Ig y ITIM) es una proteína de punto de control inmune.
  • Inhibe las funciones citotóxicas de las células T y NK a través de varios mecanismos.
  • TIGIT pertenece a la familia de proteínas tipo PVR e interactúa con CD155.

Objetivo del estudio:

  • Revisar los mecanismos de supresión inmune mediada por la TIGIT.
  • Discutir las estrategias inmunoterapéuticas emergentes dirigidas a la TIGIT.
  • Proporcionar una visión general de los ensayos clínicos actuales y las direcciones futuras para las terapias basadas en TIGIT.

Principales métodos:

  • Revisión de la literatura sobre la función de la TIGIT y las estrategias terapéuticas.
  • Análisis de los datos de ensayos preclínicos y clínicos para las terapias anti-TIGIT.
  • Discusión de enfoques alternativos más allá de los anticuerpos monoclonales.

    • Principales resultados:

    • TIGIT inhibe la inmunidad antitumoral al suprimir la actividad de las células T y NK.
    • La monoterapia con anticuerpos monoclonales contra el TIGI ha mostrado un éxito clínico limitado.
    • Las terapias combinadas y las estrategias alternativas como los inhibidores de moléculas pequeñas y las células CAR-T son prometedoras.

    Conclusiones:

    • Comprender los complejos mecanismos inhibidores de la TIGIT es crucial.
    • Las inmunoterapias combinadas dirigidas a la TIGIT ofrecen una vía prometedora para el tratamiento del cáncer.
    • Se justifica una mayor investigación sobre estrategias alternativas de orientación de TIGIT para superar las limitaciones actuales.
