Resumen

Un nuevo nanodrug combina imágenes, terapia y respuesta inmune para el cáncer de mama. Esta plataforma multimodal permite un monitoreo preciso del tumor y efectos antitumorales mejorados a través de la activación de ultrasonido.

Área de la Ciencia:

Ingeniería Biomédica Ingeniería Biomédica.
La nanomedicina es la nanomedicina.
Terapia del cáncer Terapia del cáncer.

Sus antecedentes:

El tratamiento de precisión del cáncer requiere monitoreo en tiempo real, un desafío actual.
La nanomedicina ofrece nano-plataformas integradas para mejorar el diagnóstico y tratamiento de tumores.
Las terapias activadas por ultrasonido (EE.UU.) son prometedoras para el tratamiento dirigido del cáncer.

Objetivo del estudio:

Desarrollar un nanodroga de diagnóstico multimodal para la terapia inmunosondinámica dirigida al cáncer de mama.
Para integrar sonosensibilizadores, agonistas de STING y radionúclidos para el diagnóstico y la terapia combinados.
Para permitir el monitoreo en tiempo real y la intervención terapéutica precisa en modelos de cáncer de mama.

Principales métodos:

Se ha creado un nanodrug (99mTc-NPAIE-MSA) con propiedades de luminiscencia inducida por agregación.
Utilizó la activación de US para generar especies reactivas de oxígeno y activar la vía cGAS-STING.
Incorporó 99mTc para SPECT / CT y imágenes de fluorescencia, y liberó el agonista STING MSA-2.
Evaluación de los efectos antitumorales y la inmunomodulación in vitro e in vivo.

Principales resultados:

La activación estadounidense generó especies reactivas de oxígeno, causando daño al ADN y a las mitocondrias.
La nano-plataforma activó con éxito la vía cGAS-STING y liberó MSA-2.
99mTc facilitó la orientación y el monitoreo precisos del tumor a través de modalidades de imágenes.
Se observaron efectos antitumorales significativos y inmunomodulación in vitro e in vivo.

Conclusiones:

El nanodrug desarrollado 99mTc-NPAIE-MSA es eficaz para la terapia inmunosondinámica en el cáncer de mama.
Esta plataforma multimodal ofrece capacidades precisas de diagnóstico, monitoreo y tratamiento de tumores.
La estrategia presenta un nuevo enfoque para la terapia avanzada de cáncer guiada por imágenes y la inmunomodulación.

Palabras clave:

Imágenes de imágenes nucleares.Las nanoportadoras de polímero son nanoportadoras de polímero.La terapia sonodinámica es una terapia sonodinámica.Las nanodrogas theranosticas son una especie de nanodroga.cGAS-STINGING es el nombre que se le da a este proceso.

Cancer Therapies

Cancer Therapies

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...

Targeted Cancer Therapies

Targeted Cancer Therapies

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...

Gene Therapy

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group Therapy

Group Therapy

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Behavior Therapy

Behavior Therapy

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...

Drug Therapy

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.
