Resumen
La sepsis involucra respuestas inmunes anormales. Esta revisión detalla la muerte asociada a la trampa extracelular de piroptosis y neutrófilos (NETosis), formas cruciales de muerte celular y sus interacciones en la fisiopatología de la sepsis, ofreciendo ideas terapéuticas.
Área de la Ciencia:
- Inmunología
- Fisiopatología
- Biología celular
Sus antecedentes:
- La sepsis es una condición que amenaza la vida impulsada por la desregulación del sistema inmunológico.
- Las trampas extracelulares de neutrófilos (NET) y la piroptosis son vías clave de muerte celular inmune implicadas en la sepsis.
Objetivo del estudio:
- Para explorar las funciones de la piroptosis y la NETosis en la sepsis.
- Analizar las interacciones complejas entre la piroptosis y la NETosis en el desarrollo de la sepsis.
- Identificar posibles objetivos terapéuticos y direcciones de investigación futuras.
Principales métodos:
- Revisión de la literatura centrada en los mecanismos de muerte de las células inmunes en la sepsis.
- Análisis de la fisiopatología de la sepsis, haciendo hincapié en las funciones de los neutrófilos y las células inmunes.
- Examen detallado de los mecanismos de piroptosis y NETosis y su interacción.
Principales resultados:
- La piroptosis y la NETosis son contribuyentes significativos a la fisiopatología de la sepsis.
- La interacción entre la piroptosis y la NETosis influye en la progresión de la sepsis.
- Comprender estas vías de muerte celular ofrece vías para nuevas estrategias terapéuticas.
Conclusiones:
- La piroptosis y la NETosis juegan un papel crítico en la patogénesis de la sepsis.
- Dirigirse a la interacción entre la piroptosis y la NETosis puede ofrecer nuevos enfoques terapéuticos para la sepsis.
- Se requiere más investigación para aclarar completamente estos mecanismos y sus aplicaciones clínicas.

4.8K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

01:30Overview of Cell Death
7.7K
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...

01:17Phagocytosis of Apoptotic Cells
4.0K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

01:27Acute Pyelonephritis I: Introduction
48
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...
