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...

Summary
This summary is machine-generated.

This study reveals that downregulated Alzheimer's disease (AD) risk genes correlate with amyloid-beta (Aβ) deposition in the brain. These findings link gene expression patterns to Aβ pathology, offering new therapeutic targets for AD.

Area of Science:

  • Neuroscience
  • Genetics
  • Molecular Biology

Background:

  • Alzheimer's disease (AD) is a neurodegenerative disorder marked by neuronal loss and amyloid-beta (Aβ) protein accumulation.
  • Current understanding of in vivo Aβ deposition and associated gene expression patterns in AD patients remains limited.

Purpose of the Study:

  • To investigate the relationship between in vivo Aβ deposition, measured by 11C-PIB PET, and gene expression patterns in Alzheimer's disease.
  • To identify specific AD risk genes and pathways associated with Aβ deposition.

Main Methods:

  • Collected 11C-PIB PET scans from 151 AD patients and 76 controls.
  • Analyzed transcriptional profiles of TLE risk genes using postmortem brain samples from the Allen Human Brain Atlas.
  • Integrated neuroimaging and transcriptomic data to examine gene expression and Aβ deposition correlations, followed by pathway and network analyses.

Main Results:

  • Extensive Aβ deposition was observed in the cortical regions of AD patients, particularly the temporal-parietal and frontal-parietal cortices.
  • Aβ deposition patterns spatially correlated with the expression of AD risk genes (r=0.759, p<0.001).
  • Identified 223 downregulated genes, enriched in Notch signaling and neuronal differentiation pathways, with key genes like EGFR, RHOA, VASP, RDX, and MSN implicated in AD pathogenesis.

Conclusions:

  • Spatial expression patterns of downregulated AD risk genes are associated with in vivo Aβ deposition patterns in Alzheimer's disease.
  • These imaging-transcriptomic findings suggest potential for developing molecular and genetic network-based therapeutic strategies for AD.
