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.

CD163 protein levels in cerebrospinal fluid correlate with Alzheimer's disease (AD) biomarkers like tau and amyloid-beta. This suggests CD163 may indicate advanced neuroinflammation and neurodegeneration in AD patients.

Area of Science:

  • Neuroscience
  • Immunology
  • Biochemistry

Background:

  • Neuroinflammation is a key feature in Alzheimer's disease (AD) pathophysiology.
  • CD163, a marker of neuroinflammation, shows increased expression in AD but its relationship with core AD biomarkers is unclear.
  • This study investigates the association between CD163 protein and key AD biomarkers: astrogliosis, amyloid-beta (Aβ), and tau.

Purpose of the Study:

  • To evaluate the impact of CD163 protein levels on astrogliosis, Aβ, and tau biomarkers in Alzheimer's disease.
  • To explore the relationship between CD163 and established AD fluid and imaging biomarkers across different cognitive states.

Main Methods:

  • Utilized data from 170 cognitively unimpaired (CU), 411 mild cognitively impaired (MCI), and 138 dementia individuals from the ADNI cohort.
  • Employed generalized linear mixed models to assess associations between cerebrospinal fluid (CSF) CD163 levels and AD biomarkers (total-tau, Aβ42, pTau181, Aβ-PET, MMSE, hippocampal volume).
  • Used Akaike Information Criterion (AIC) to compare model fit for analyzing CD163 as a function of biomarkers.

Main Results:

  • No significant differences in CD163 protein or gene expression were found between CU, MCI, and dementia groups.
  • Positive associations were observed between CSF CD163 levels and total-tau, Aβ42, and pTau181 across all cognitive groups (CU, MCI, and dementia).
  • In MCI, CD163 CSF levels negatively correlated with Mini-Mental State Examination (MMSE) scores, while no association was found with hippocampal volume in any group.

Conclusions:

  • The positive correlation between CSF CD163 levels and tau/Aβ biomarkers in dementia patients reinforces CD163's role as a potential indicator of advanced neuroinflammation and neurodegeneration.
  • The analyzed biomarkers more accurately describe the dementia group, highlighting the precision of CD163 correlations in this cohort.
  • These findings suggest CD163 may serve as a valuable biomarker in understanding the inflammatory and neurodegenerative processes in Alzheimer's disease.
