Summary
Tuberculosis bacteria use epigenetics to evade immune responses. Targeting these epigenetic changes offers a promising strategy for new host-directed therapies against tuberculosis (TB).
Area of Science:
- Molecular Biology
- Immunology
- Pathogenesis
Background:
- Tuberculosis (TB) remains a leading infectious cause of death worldwide.
- Mycobacterium tuberculosis (M.tb) employs epigenetic modifications to evade host immunity.
- Current anti-TB drugs face challenges of drug resistance, toxicity, and long treatment durations.
Purpose of the Study:
- To review the role of epigenetic alterations in TB pathogenesis.
- To discuss epigenetic-based therapeutic strategies for TB treatment.
- To highlight the potential of host-directed therapies targeting epigenetics.
Main Methods:
- Literature review of studies on epigenetics in TB.
- Analysis of M.tb's manipulation of host epigenome.
- Exploration of reversible epigenetic changes for therapeutic intervention.
Main Results:
- M.tb significantly impacts the host epigenome to favor pathogen survival.
- Epigenetic modifications alter immune gene expression, subverting host defenses.
- These host epigenome changes are reversible.
Conclusions:
- Epigenetic mechanisms are crucial in TB pathogenesis.
- Exploiting reversible epigenetic changes presents a viable avenue for novel host-directed therapies.
- Epigenetic therapies could offer effective TB treatment with reduced resistance and toxicity.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

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...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Defense Against Bacterial Pathogens
1.7K
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...
