Tuberculosis lymph node granulomas: using transcriptomics to discover immunopathology paradigms and guide
The Journal of Clinical Investigation
|August 2, 2021
Summary
Researchers identified Sphingosine kinase 1 as a potential target for tuberculosis treatment. This finding could lead to new host-directed therapies to combat the infection and reduce disease severity.
Area of Science:
- Immunometabolism
- Tuberculosis research
- Host-pathogen interactions
Background:
- Immunometabolism is critical in tuberculosis (TB) host defense, susceptibility, and disease progression.
- Unbiased studies confirm the central role of immunometabolic pathways in TB pathogenesis.
- Understanding these pathways is key to developing effective host-directed therapies.
Purpose of the Study:
- To investigate immunometabolic pathways in human lymph node tuberculosis.
- To identify novel druggable targets for host-directed TB therapy.
- To explore the potential of targeting the sphingolipid pathway for improved TB treatment.
Main Methods:
- Analysis of human lymph node tuberculosis samples.
- Controlled experimental studies.
- Investigation of the sphingolipid metabolic pathway.
Main Results:
- Sphingosine kinase 1 was identified as a druggable target in tuberculosis.
- This target shows potential to support the infected host.
- The sphingolipid pathway emerged as a key area for further investigation.
Conclusions:
- Sphingosine kinase 1 represents a promising target for host-directed tuberculosis therapy.
- Further research into sphingolipid pathway manipulation is warranted.
- Animal models are crucial for validating the therapeutic potential and understanding the role of this pathway in TB.

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...
