Inflammafish: Cross-talk between inflammation and autophagy in tuberculosis
Effective host defence against tuberculosis bacteria depends on a properly balanced level of inflammation. The Inflammafish project uses zebrafish larvae to study how autophagy controls this inflammation and vice versa.

Development of an intradermal tuberculosis vaccine by combining dissolvable microneedle arrays and Mycobacterium tuberculosis antigen-containing nanoparticles
Mycobacterium tuberculosis (Mtb), the pathogen causing tuberculosis (TB), is the leader among all pathogens responsible for the most human deaths today and it is considered as one of the top 10 causes of death worldwide. There is an increasing occurrence of multidrug-resistant and even totally drug-resistant…

Disrupted movement makes macrophages more lethal to tuberculosis bacteria
Macrophages – the front line of our immune system – protect us from infections. But in the case of the tuberculosis bacteria, this often goes wrong. The group of Annemarie Meijer from the Leiden Institute of Biology has now discovered that macrophages in zebrafish are better able to eliminate tuberculosis…

Development of an effective, safe, and painless intradermal tuberculosis vaccine based on microneedles loaded with antigen-containing nanoparticles
Tuberculosis (TB) is a major global health problem caused by the bacterium Mycobacterium tuberculosis (Mtb). In 2015, there were estimated to be 10.4 million new cases and 1.8 million deaths ascribed to TB, making it one of the top 10 causes of death worldwide. Unfortunately, the only current registered…

Hypoxic Signalling and Tuberculosis
IBL-researcher Phil Elks in the group of Annemarie Meijer won the Cell Observatory Publication of the Year 2013. He received the award for his paper in PLoS Pathogens, showing that activation of hypoxia signaling protects against mycobacterial infection.
-
New insight into tuberculosis infection
Michiel van der Vaart with a team from Leiden University and the LUMC, led by IBL-researcher Annemarie Meijer, discovered that DRAM1 is a protein that regulates anti-bacterial autophagy, a defense mechanism against infections such as tuberculosis.

Taking a closer look at resistance to tuberculosis bacteria
Though tuberculosis can be cured today, new resistant strains of the bacteria are becoming a growing problem in the medical world. Biologist Annemarie Meijer and her colleagues are studying resistance to this disease. Their research is already yielding several interesting clues that could help the development…

Cleaning up tuberculosis and salmonella infections
The cellular recycling system in zebrafish is capable of eating harmful bacteria and thus resist infections such as tuberculosis and salmonellosis. That is written by Leiden biologists from the group of Annemarie Meijer. Stimulating this form of defence could be used in new treatment methods against…

Attacking tuberculosis bacteria: an interview with Mónica Varela
This summer postdoctoral researcher Mónica Varela from the Institute of Biology Leiden was awarded a Veni grant from the Dutch Research Council (NWO). Six questions about her project and hopes for the future.

Structural characterization of bacterial proteins involved in antibiotic resistance and peptidoglycan biosynthesis
This thesis describes the structural and biochemical characterization of the β-lactamase BlaC from Mycobacterium tuberculosis (Mtb), and the Alr and YlmE proteins from Streptomyces coelicolor A3(2).Mtb is the main cause of tuberculosis.

Selective autophagy in host defense against mycobacterial infection
The effective treatment of tuberculosis (TB) remains a major challenge to global health.

Dynamics of a β-lactamase
BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Design of dissolvable microneedles for intradermal TB vaccination
Tuberculosis is an infectious disease which is spreaded through the air. It is caused by Mycobacterium tuberculosis and it led 1.7 million people to death in 2016. This mortarlity rate is concentrated in developing countries such as Indonesia, Philippines, Pakistan, and South Africa. These numbers make…

EU awards 18 million euros for research into new antibiotics
An international consortium of research groups is aiming to develop novel antibiotics against the tuberculosis bacteria and two other deadly bacteria. The European Union has awarded a total of 18 million euros to the RespiriTB and RespiriNTM projects. Researchers from the Leiden University Medical Centre…

Inaugural lecture: Innate immunity into the picture
Tuberculosis bacteria and other intracellular pathogens use cells of our immune system as Trojan horses to spread into tissues. Annemarie Meijer, professor of immunobiology, explains how research into innate defence mechanisms using zebrafish inspires novel strategies for infectious disease treatmen…

Scientists find strong evidence that wasting syndrome is the same for all organisms
An interdisciplinary team of Leiden researchers has discovered that wasting syndrome, a severe byproduct of tuberculosis, is the same for all humans and animals studied. The discovery offers new opportunities to investigate the still insufficiently understood condition. The scientists also developed…
