EXTENDED: From River Blindness to Malaria Control – The Ivermectin Story (with Carlos Chaccour and Joseph Mwangangi)
Johns Hopkins Malaria Minute
In Kwale, Kenya, where bed nets alone can’t stop malaria, researchers are testing ivermectin – a drug long used to treat parasitic infections – as a new way to kill mosquitoes. Trials show a 26% drop in malaria cases and added benefits against other mosquito-borne diseases, suggesting ivermectin could be a scalable, community-driven tool in the fight against insecticide resistance.

What Severe Malaria Cases Have In Common
Johns Hopkins Malaria Minute
Although severe malaria presents in different clinical forms – such as cerebral malaria or severe malarial anemia – a new study reveals that all severe cases have one thing in common: a shared inflammatory signature Transcript Whilst most cases of malaria are mild, some take a dangerous turn. In severe cases, the malaria parasite can overwhelm the body, disrupting the blood-brain barrier and leading to cerebral malaria, or destroying so many red blood cells that it triggers life-threatening anemia. Now, a new study has taken a closer look at this progression – from uncomplicated malaria...

Bed Nets That Target Parasites, Not Just Mosquitoes
Johns Hopkins Malaria Minute
How next-generation bed nets could stop malaria by killing the parasites inside mosquitoes, not just the mosquitoes themselves. Transcript Bed nets have long been a cornerstone of vector control. Coated with insecticide, they serve a dual purpose: preventing bites and killing mosquitoes. But what if those nets could do more – not only kill the mosquitoes, but for those they don’t kill because of increasing insecticide resistance, at least kill the parasites hidden inside them? Researchers assembled a library of antiparasitic compounds active against the form of the parasite in the mosquito...

Mismatch Between Malaria Vaccines and Local Parasite Strains in Ethiopia
Johns Hopkins Malaria Minute
A recent study in Ethiopia reveals that local malaria parasite strains differ genetically from those targeted by current vaccines, potentially reducing their effectiveness. Transcript The recent introduction of two malaria vaccines in sub-Saharan Africa represents a major success in global health, and the culmination of decades of research and development. The two jabs – RTS,S and R21 – target a protein on the surface of the malaria parasite as it enters the skin, called the circumsporozoite protein, or CSP. The vaccines are based on a specific form of CSP. The challenge is that there are...

Malaria Advocacy on Capitol Hill: Funding, Research, and Global Impact
Johns Hopkins Malaria Minute
The podcast explores the importance of advocacy for malaria research and control. It follows over 120 advocates gathering in Washington, DC, as part of the ‘United to Beat Malaria’ campaign, urging Congress to continue supporting global malaria efforts. Key topics include: The US President’s Malaria Initiative (PMI), founded in 2005, which provides bed nets, test kits, and treatments to combat malaria The role of global partnerships, including the Global Fund, in distributing resources efficiently. How Uganda’s malaria response is supported by international funding for the...

Transcript
Whilst most cases of malaria are mild, some take a dangerous turn. In severe cases, the malaria parasite can overwhelm the body, disrupting the blood-brain barrier and leading to cerebral malaria, or destroying so many red blood cells that it triggers life-threatening anemia. Now, a new study has taken a closer look at this progression – from uncomplicated malaria to severe disease.
Researchers looked at three factors: Transcriptomics, the genes being expressed; proteomics, the proteins being produced; and metabolomics, the metabolites and small molecules present. Using a matched-pairs design, they compared blood samples of children with severe malaria versus children with uncomplicated disease.
The finding? Although different types of severe malaria can be distinguished by other factors, they all share a ‘common signalling pattern.’
Two proteins stood out: MMP8 and MMP9 – and those proteins are both involved, in different ways, in the breakdown of the extracellular matrix – the scaffolding between cells. The finding gives researchers new clues into how malaria becomes deadly, and may open the door to better-targeted treatments – or even a vaccine against severe malaria - in the future.
