Infection01:20

Infection

11.6K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection II: Pathophysiology

524
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Cystic Fibrosis: Pathogenesis

676
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,...

Stages of Infection

64.7K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

2.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Área de la Ciencia:

  • Neurociencia; Genética; Farmacología

Sus antecedentes:

  • El desarrollo de fármacos para la enfermedad de Alzheimer (EA) enfrenta desafíos debido a las limitaciones en los modelos animales.
  • El modelo de ratón genéticamente diverso AD-BXD exhibe un inicio y un declive cognitivo variables, lo que refleja la EA humana.
  • Trabajos anteriores identificaron una firma de expresión génica de resiliencia en neuronas excitatorias.

Objetivo del estudio:

  • Identificar firmas de expresión génica novedosas y conservadas y subtipos neuronales asociados con la resiliencia a la EA.
  • Integrar datos transcriptómicos de ratones y humanos para anotaciones de relevancia traslacional.
  • Analizar la expresión génica diferencial en subclases neuronales utilizando una métrica continua de resiliencia cognitiva.

Principales métodos:

  • Se integraron datos transcriptómicos de una sola célula del modelo AD-BXD con datos humanos ROSMAP.
  • Se anotaron células de ratón utilizando una taxonomía celular humana.
  • Se realizó un análisis de expresión génica diferencial en subclases neuronales con una tarea de condicionamiento al miedo como covariable.

Principales resultados:

  • Una métrica cognitiva continua mostró un mayor poder estadístico que una métrica categórica para el análisis de la expresión génica diferencial.
  • Se identificaron genes expresados diferencialmente (DEGs) en subtipos de neuronas excitatorias e inhibitorias.
  • Las neuronas excitatorias de la capa 2/3 mostraron la mayor cantidad de DEGs, incluido SCG5, que está relacionado con el riesgo de EA.

Conclusiones:

  • Se identificó una firma transcriptómica asociada con la resiliencia cognitiva en un modelo de ratón genéticamente diverso de EA.
  • La investigación en curso investigará firmas de resiliencia y tipos celulares conservados entre especies.
  • Los análisis futuros se centrarán en la nominación y el reposicionamiento de dianas farmacológicas para la validación preclínica.
