Synaptic plasticity processes, which underlie learning and memory formation, require RNA to be translated local to synapses. The synaptic tagging hypothesis has previously been proposed to explain how mRNAs are available at specific activated synapse...

Cell type–specific super-resolution imaging reveals an increase in calcium-permeable AMPA receptors at spinal peptidergic terminals as an anatomical correlate of inflammatory pain (2019)
Journal Article
Woodhams, S. G., Markus, R., Gowler, P. R., Self, T. J., & Chapman, V. (2019). Cell type–specific super-resolution imaging reveals an increase in calcium-permeable AMPA receptors at spinal peptidergic terminals as an anatomical correlate of inflammatory pain. PAIN, 160(11), 2641-2650. https://doi.org/10.1097/j.pain.0000000000001672

Spinal hyperexcitability is a key event in the development of persistent pain, and arises partly from alterations in the number and localization of α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA)-type glutamate receptors. However, determinin...

Neisseria meningitidis, a major cause of bacterial meningitis and septicaemia, secretes multiple virulence factors, including the adhesion and penetration protein (App) and meningococcal serine protease A (MspA). Both are conserved, immunogenic, type... Read More about Nuclear trafficking, histone cleavage and induction of apoptosis by the meningococcal App and MspA autotransporters.

Open Biology, 4(1), Article 130202. https://doi.org/10.1098/rsob.130202

Campylobacter jejuni is an important cause of human foodborne gastroenteritis; strategies to prevent infection are hampered by a poor understanding of the complex interactions between host and pathogen. Previous work showed that C. jejuni could bind...

Open Biology, 3, Article e130048. https://doi.org/10.1098/rsob.130048

Interactions between commensal pathogens and hosts are critical for disease development but the underlying mechanisms for switching between the commensal and virulent states are unknown. We show that the human pathogen Neisseria meningitidis, the lea... Read More about Pro-inflammatory cytokines can act as intracellular modulators of commensal bacterial virulence.

Adenosine-A3 receptors in neutrophil microdomains promote the formation of bacteria-tethering cytonemes (2013)
Journal Article

The A3‐adenosine receptor (A3AR) has recently emerged as a key regulator of neutrophil behaviour. Using a fluorescent A3AR ligand, we show that A3ARs aggregate in highly polarized immunomodulatory microdomains on human neutrophil membranes. In additi...
