Resumen
Las células modificadas se pueden programar para terapias utilizando la muerte o detención celular controlada, no solo la viabilidad. Este enfoque mejora la seguridad, previsibilidad y estabilidad terapéutica para aplicaciones en la modulación inmune, administración de fármacos y regeneración de tejidos.
Área de la Ciencia:
- Ingeniería Biomédica Ingeniería Biomédica.
- La terapéutica celular es una terapia celular.
- Biología sintética Biología sintética.
Sus antecedentes:
- La ingeniería celular actual se centra predominantemente en las células vivas, pasando por alto el potencial terapéutico de los estados no viables o detenidos.
- Existe un espectro de células viables a células muertas, cada una de las cuales ofrece propiedades únicas para aplicaciones terapéuticas.
Objetivo del estudio:
- Explorar la manipulación controlada de la muerte y detención celular para desarrollar terapias basadas en células efectivas, más seguras y predecibles.
- Introducir un marco para comprender las terapias de células vivas, moribundas y muertas de ingeniería.
- Examinar las tecnologías habilitantes para estas terapias celulares avanzadas.
Principales métodos:
- Apoptosis de ingeniería y detención irreversible del crecimiento.
- Diseño de circuitos genéticos sintéticos para funciones celulares programadas.
- Utilizando herramientas genéticas, físicas y basadas en materiales para la manipulación celular.
Principales resultados:
- La muerte o detención celular programada permite salidas funcionales sin plena viabilidad, reduciendo la heterogeneidad celular.
- Las estrategias diseñadas de muerte celular / detención mejoran la estabilidad terapéutica y amplían la ventana terapéutica.
- Estos enfoques son aplicables en diversos dominios biomédicos, incluida la modulación inmune, la administración de medicamentos y la regeneración de tejidos.
Conclusiones:
- La manipulación controlada de la muerte y detención celular ofrece un nuevo paradigma para las terapias basadas en células.
- Las células vivas, moribundas y muertas diseñadas proporcionan soluciones terapéuticas programables y consistentes.
- Esta perspectiva allana el camino para terapias celulares avanzadas y confiables en varios campos médicos.

01:18Autophagic Cell Death
4.6K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:30Overview of Cell Death
10.2K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:13Therapeutic Index
6.9K
The therapeutic index of a drug is a key parameter in pharmacology that quantifies the relative safety of a drug by calculating the ratio between the dose that causes toxicity in half the population (50%) to the dose that proves to be effective for half the population (50%). It provides a spectrum of doses for a particular drug ranging from effective to potentially toxic. To illustrate, consider an anticoagulant agent like warfarin. It possesses a narrow window within its therapeutic index to...

01:30Therapeutic Communication
8.6K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...
