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

521
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

674
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
  • Genomics
  • Computational Biology

Background:

  • Single-cell studies are crucial for understanding Alzheimer's Disease (AD) complexity.
  • Identifying disease-associated cell states and molecular mechanisms is key for personalized treatments.

Purpose of the Study:

  • To create a comprehensive human brain single-nuclei RNA-seq (snRNA-seq) atlas for neurological disorders.
  • To harmonize clinical and pathological data for robust disease group definition.
  • To leverage generative AI for advanced snRNA-seq data harmonization and cell type annotation.

Main Methods:

  • Generated a large-scale human brain snRNA-seq atlas (approx. 14 million nuclei).
  • Harmonized clinical data (pathological/clinical diagnoses) and snRNA-seq data using a generative AI foundation model.
  • Performed hierarchical cell type annotation (supervised/unsupervised) across 33 brain regions.

Main Results:

  • The atlas includes 2,239 samples (control, AD, resilience, PART, other neurological diseases).
  • Identified over 50 cell types, including microglia subtypes (DAM, tau, MHC) and neuron subtypes (Sst, dopaminergic).
  • Found Sst neuron loss in AD, identified resilience proteins (e.g., PLCG2 in DAM), and noted decreased PLCG2 expression with aging in AD.

Conclusions:

  • Generated a large-scale human brain snRNA-seq atlas for neurodegenerative disease research.
  • Provides a valuable digital resource for exploring diverse neurodegenerative conditions.
  • Offers insights into Alzheimer's disease mechanisms and potential resilience factors.
