Summary
Trehalose 6,6' dimycolate (TDM) is a key factor in tuberculosis (TB) pathogenesis. Understanding TDM and its receptors may lead to new TB treatments and limit disease progression.
Area of Science:
- Microbiology
- Immunology
- Pathogenesis
Background:
- Tuberculosis (TB) is a global health challenge with lengthy treatment and no vaccine for the primary form.
- The mycobacterial glycolipid trehalose 6,6' dimycolate (TDM), also known as cord factor, is increasingly implicated in TB pathogenesis.
Purpose of the Study:
- To elucidate the role of TDM in TB pathogenesis.
- To explore the potential of targeting TDM for novel therapeutic strategies.
Main Methods:
- Review of existing evidence on TDM's function in TB.
- Discussion of recently identified TDM receptors and their implications.
Main Results:
- TDM aids TB bacilli in evading macrophage killing.
- TDM impairs antigen presentation and T-cell responses.
- TDM is involved in granuloma formation, caseation, and potentially post-primary disease.
Conclusions:
- TDM is a critical virulence factor in TB.
- Understanding TDM and its receptors offers a promising avenue for developing targeted TB therapeutics.
- Targeting TDM could mitigate clinical pathologies associated with TB disease.

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 (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:15Drugs that Stabilize Microtubules
2.2K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

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.

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...

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
