Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.2K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Liver Histology01:27

Liver Histology

2.8K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Transcytosis of IgG01:15

Transcytosis of IgG

3.5K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

EPS and iPS Cells in Disease Research01:21

EPS and iPS Cells in Disease Research

3.1K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

522
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

117
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Resumen
Este resumen es generado por máquina.

Las histiocitosis son trastornos raros de las células mieloides que afectan a cualquier órgano, a menudo diagnosticados tarde en los adultos. Las mutaciones genéticas que activan la vía de la MAP quinasa son clave, y las terapias dirigidas ofrecen nuevas esperanzas.

  • En el campo de la oncología
  • Enfermedades raras

Sus antecedentes:

  • Las histiocitosis son trastornos raros y heterogéneos que implican la infiltración de células mieloides de varios órganos.
  • Estas condiciones pueden afectar a cualquier grupo de edad, pero el diagnóstico a menudo se retrasa en los adultos debido a presentaciones variadas.

Objetivo del estudio:

  • Revisión de los hallazgos clínicos, histológicos y moleculares en casos de histiocitosis.
  • Análisis de los resultados del tratamiento, incluida la respuesta a terapias dirigidas.

Principales resultados:

  • Las mutaciones somáticas en los genes de la vía de la cinasa MAP se identifican con frecuencia en los tejidos afectados y, a veces, en la sangre.
  • Los inhibidores dirigidos de BRAF o MEK han demostrado un éxito significativo en la terapia de rescate.

Conclusiones:

  • El diagnóstico preciso requiere investigaciones exhaustivas y tipificación molecular para la evaluación del pronóstico.
  • Si bien las terapias dirigidas son efectivas, las estrategias de tratamiento óptimas y la prevención de complicaciones neurológicas requieren más investigación.
