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...

Area of Science:

  • Neuroscience
  • Genetics
  • Molecular Biology

Background:

  • Cognitive resilience is the capacity to maintain cognitive function despite Alzheimer's disease (AD) pathology.
  • Studying resilience reveals natural protective mechanisms and potential therapeutic strategies for AD.
  • This research integrates genetic, transcriptomic, and cellular data to explore cognitive resilience.

Purpose of the Study:

  • To investigate the molecular and cellular basis of cognitive resilience in the context of Alzheimer's disease.
  • To identify genetic and transcriptomic signatures associated with cognitive resilience.
  • To map neuronal subtypes and pathways involved in protection against AD pathology.

Main Methods:

  • Utilized bulk and single-nucleus RNA sequencing data from the ROSMAP cohort (n=679).
  • Classified subjects into AD, resilient, and control groups based on cognitive status and neuropathology.
  • Performed genetic, transcriptomic, and cell population analyses to identify resilience markers and pathways.

Main Results:

  • Cognitive resilience correlated with an intermediate AD polygenic risk score and specific gene expression changes (e.g., GFAP upregulation, KLF4 downregulation).
  • Excitatory neurons in resilient individuals showed reorganized protein folding and degradation pathways.
  • Distinct resilient neuronal subpopulations in the entorhinal cortex utilized neurotrophin and angiopoietin signaling; RBFOX1 and KIF26B were identified as potential markers.

Conclusions:

  • Cognitive resilience is characterized by specific cellular and molecular features, including the roles of excitatory and inhibitory neurons.
  • The study highlights the importance of maintaining the excitatory-inhibitory balance, which is often disrupted in AD.
  • Findings provide a basis for developing targeted AD therapies by leveraging natural resilience mechanisms.
