Chocolate directly affects immune system performance. Stripping back the confounding effects of other components, such as sugar, cocoa itself promotes beneficial changes which are reflected in levels of pro- and anti-inflammatory cytokines.

Immune reactions are a hazard of protein drug development. Why are some foreign proteins such as silk and botulinum toxin (Botox) tolerated when other proteins are not?

Cancer drugs struggle to reach a tumour's core. Cambridge researchers develop cellular 'Trojan horse' to deliver cancer drugs more effectively.

As ubiquitous messengers, exosomes play a role in how our bodies manage energy. From adipocytes to the gut microbiome, new insights into how exosomes modulate human metabolism might be providing a glimpse into the future of metabolic disease treatment.

It is said that a drug without side effects is a drug without efficacy. Could the same be true of artificial sweeteners? Are we hoping too much that the sweetness we crave can be satisfied without the normal cost in calories, cavities and surges in blood sugar levels?

Both hormones and exosomes regulate physiological processes by transmitting signals to distant cells. Although clearly distinct, these two systems interact in complex and important ways.

Look hard enough and microscopic crystals are common in animals, including humans. Naturally occurring crystals in-vivo play important roles in health as well as disease. Recombinant protein crystals are also being used, or are in development, as drug delivery systems providing therapies to treat diseases including diabetes, cancer, osteoarthritis and macular degeneration.

When proteins are used therapeutically, each protein and its target pair present unique challenges for delivery. Placing proteins in the right place (targeting) for a sufficient period (sustained delivery) to achieve efficacy requires solutions appropriate to each drug.

Pattern recognition is one of the mechanisms by which the immune system discriminates pathogens from self. Immune cells are not simply identifying common pathogenic patterns, but instead, respond to fragments of pathogens released during unsuccessful pathogenic adaptation activities.
