Resumen
A medida que envejecemos, los procesos naturales de curación de heridas del cuerpo pueden funcionar mal, contribuyendo a enfermedades relacionadas con la edad como la inflamación y la fibrosis. Esta revisión explora cómo estas vías de curación pueden desencadenar el desarrollo de la enfermedad con el tiempo.
Área de la Ciencia:
- Mecanismos del envejecimiento y la enfermedad
- Las vías de reparación celular
- Inestabilidad genómica
Sus antecedentes:
- La era del genoma reveló el papel del envejecimiento en las enfermedades, más allá de las mutaciones.
- La curación de la herida es crucial para la reparación en individuos más jóvenes.
- El daño tisular y las mutaciones se acumulan con la edad.
Objetivo del estudio:
- Revisar cómo los procesos de cicatrización de heridas pueden iniciar la enfermedad.
- Explorar la apropiación indebida de las vías de reparación en el envejecimiento.
- Para conectar la cicatrización de heridas con patologías relacionadas con la edad.
Principales métodos:
- Revisión de la literatura existente sobre la curación de heridas y el envejecimiento.
- Análisis de los mecanismos moleculares y celulares en las enfermedades.
- Centrarse en las enfermedades epiteliales (pulmón, piel) con implicaciones más amplias.
Principales resultados:
- El envejecimiento puede causar la cicatrización de heridas para promover la inflamación, la fibrosis y la señalización neoplásica.
- Las vías de reparación disfuncionales están implicadas en la insuficiencia orgánica relacionada con la edad.
- Mecanismos similares pueden afectar a los tejidos cardíacos, musculares y neuronales.
Conclusiones:
- La curación de heridas, aunque es esencial, puede contribuir paradójicamente a la enfermedad con la edad.
- Comprender estas vías es clave para abordar las enfermedades relacionadas con la edad.
- Se necesitan más investigaciones sobre las enfermedades epiteliales, cardíacas, musculares y neuronales.

01:28Phases of Wound Repair
5.9K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

01:24Chronic Pancreatitis I: Introduction
72
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:26Factors Affecting the Risk of Infection
11.4K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:19Overview of Regeneration and Repair
3.9K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
