Tuberculosis News and Research

RSS

Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you think you have been exposed, you should go to your doctor for tests as soon as possible. You are more likely to get TB if you have a weak immune system.

Ancient DNA research tracks tuberculosis transmission chains

Tuberculosis is the second most common cause of death worldwide by an infectious pathogen after Covid-19, but many aspects of its long history with humans remain controversial.

Study findings open new avenues for research into host-directed therapies for TB

A*STAR’s GIS and ID Labs have discovered KCNJ15, a gene linked to the human immune system’s ability to combat TB and maybe other infectious diseases.

Researchers map proteo-genomic connections between different human diseases

Hundreds of connections between different human diseases have been uncovered through their shared origin in our genome by an international research team led by scientists from the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge, challenging the categorisation of diseases by organ, symptoms, or clinical speciality.

Researchers develop a novel sensor to detect chemical changes in immune cells

Three chemists from the Indiana University Bloomington developed a novel sensor to identify chemical changes in immune cells at the time of the pathogen breakdown.

Study reveals strong link between infection rates and authoritarian attitudes, governance

According to psychologists, in addition to our physiological immune system, we also have a behavioral one: an unconscious code of conduct that helps us stay disease-free, including fear and avoidance of unfamiliar - and so possibly infected - people.

Combining bacteriophages with antibiotics to treat antibiotic-resistant infections

Mycobacterium abscessus, a relative of the bacteria that cause tuberculosis and leprosy, is responsible for particularly severe damage to human lungs and can be resistant to many standard antibiotics, making infections extremely challenging to treat.

Cell-analysis method could pave the way for new strategies to fight tuberculosis

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

Researchers suggest new strategies for finding drugs that neutralize key enzymes

Scientists from the UK's University of Bath explore racemases - an important type of enzyme that is linked to certain cancers and other life-threatening diseases while also being critical to cell function - in a paper published in the prestigious journal Chemical Society Reviews. The scientists also propose new strategies for finding drugs that neutralize these enzymes.

Study shows metabolic pathways by which Mycobacterium tuberculosis consumes its favorite nutrients

Mycobacterium tuberculosis is remarkable because it can live in the human host for decades.

Scientists discover how immune response to TB differs in adults and newborn babies

The immune response to tuberculosis (TB) differs in adults and newborn babies due to the way immune cells use energy to kick into gear in a bid to kill the bacteria. This fresh discovery - just published in leading journal, Frontiers in Immunology - offers hope for improving treatments for what remains a deadly disease.

Study explains molecular mechanisms of drug resistance in Mycobacterium tuberculosis

A group of researchers from France, Germany, Belarus, Japan, and Russia and headed by a scientist from Skolkovo Institute of Science and Technology (Skoltech) has discovered how Mycobacterium tuberculosis survives in iron-deficient environments by using rubredoxin B (RubB)—a protein that belongs to the rubredoxin family and plays a significant role in adapting to varying environmental conditions.
