Anti-microbial resistance: fixing the innovation gap

Anti-microbial resistance: fixing the innovation gap

Each year, 1.27 million deaths are caused by drug-resistant microbes. These bugs are currently developing resistance at a faster rate than new drugs are developed. In 30 years’ time, if this innovation gap continues, 10 million people are forecast to die each year from infections that were once treatable. Such a toll would surpass even cancer as a cause of mortality. With such a grave threat to human health, why isn’t more being done? Why aren’t more antibiotics being developed?

Does too little phagocytosis lead to autism?

Does too little phagocytosis lead to autism?

Tissue remodeling and homeostasis are the processes that modulate and maintain the size and shape of tissues. Phagocytosis plays an important role in these processes. A recent publication in PNAS provides evidence that a mutation that reduces the efficiency of phagocytosis may lead to abnormalities in brain development that are associated with enlarged brains seen in some instances of autism.

A clear vision for the future of curing retinal diseases

A clear vision for the future of curing retinal diseases

It is accepted wisdom that the visual sense is the dominant of the five senses for us humans. A notion that also has translated into sensory research. Or as the author of a paper in 2019 asked “Why Is There So Much More Research on Vision Than on Any Other Sensory Modality?” in which he observed that more textbook and journal article inches are spent on vision than on any other sensory modality across multiple disciplines ranging from biomedical sciences to perception and cognitive psychology.

Exosomes for targeted doxorubicin chemotherapy

Exosomes for targeted doxorubicin chemotherapy

Chemotherapy, using chemicals that are particularly toxic to rapidly dividing cancer cells, is the most commonly used cancer treatment, often in combination with surgery and/or radiotherapy. However, the side effects of chemotherapy are severe. Exosomes may offer a way of better targeting chemotherapy to cancer cells.

Exosomal-PD-L1 predicts treatment response in melanoma patients

Exosomal-PD-L1 predicts treatment response in melanoma patients

Many cancers have developed an efficient way of blocking the body’s natural immune response by overexpressing a protein called programmed death ligand-1 (PD-L1). Antibodies that neutralize PD-L1 are highly effective in some patients. Exosome-based diagnostics can predict responders.

Exosome therapeutics in development for treating Covid

Exosome therapeutics in development for treating Covid

Times of crisis can precipitate rapid technological development and the Covid-19 crisis is presenting an opportunity for new therapeutic modalities. Pfizer/BioNTech and Moderna’s Covid vaccines which both rely on RNA have been ground-breaking. Could Covid-19 also clear the path for the first exosome therapeutics?

Diseases in a dish: Challenges of iPSC-based disease modelling

Diseases in a dish: Challenges of iPSC-based disease modelling

Despite iPSCs having potential in many biomedical applications, there are currently major challenges that need to be addressed to unleash the full potential of iPSCs for disease modelling, both in clinical settings and their use for safety pharmacology to provide more effective and safer regenerative therapy.
