Abstract

Insights

Mycobacterium avium subspecies paratuberculosis (MAP) shows high affinity for enteric glial cells, suggesting a role in Crohn's disease pathogenesis. Understanding this interaction may reveal new therapeutic targets for this complex inflammatory condition.

Area of Science:

  • Gastroenterology
  • Microbiology
  • Neuroscience

Background:

  • Crohn's disease is a chronic inflammatory bowel disease with complex etiology.
  • Enteric glial cells play a crucial role in maintaining intestinal homeostasis and immune responses.

Purpose of the Study:

  • To investigate the role of enteric glial cells in the context of Mycobacterium avium subspecies paratuberculosis (MAP) infection.
  • To determine the interaction between MAP and enteric glial cells in relation to Crohn's disease.

Main Methods:

  • Performed MAP adhesion experiments on isolated enteric glial cells.
  • Analyzed the expression of MAP sigma factors during infection under various growth conditions.

Main Results:

  • Demonstrated a high affinity of MAP for enteric glial cells, a novel finding.
  • Characterized the expression patterns of MAP sigma factors in response to host cell interaction.

Conclusions:

  • The high affinity of MAP to enteric glial cells highlights their potential significance in Crohn's disease pathogenesis.
  • Further research into the mechanisms of inflammation altering enteric neural control could lead to innovative Crohn's disease treatments.

Tuberculosis01:23

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

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...
