Nociception as a mechanism of sensing noxious stimuli and escaping potential harm is widely conserved across metazoan species, including the fruit fly. We use the adult Drosophila to study molecular mechanisms that are activated in peripheral somatosensory neurons (nociceptors) upon injury – mimicking nociceptive sensitisation similar to that observed in human chronic pain conditions. Identification of molecular mechanisms & markers involved in nociceptive sensitisation facilitates the use of genetic biosensor tools for further mechanistic and pharmacological studies.

Diseases of the Nervous System
SBBS is home to a number of Investigator groupings that work in collaboration toward shared research questions in relation to disorders of the nervous system and neurodegeneration. Research topics cover multiple sclerosis, prion based diseases, Alzheimer’s disease, movement disorders including dystonia. Drawing expertise from neuroscientists and pharmacologists, considerable emphasis is placed on the development of neurotherapeutics.
Research Interests: Cilia, C. elegans, intraflagellar transport, Ciliopathy, intracellular trafficking, Bardet Biedl syndrome, basal body, flagella.
RESEARCH INTERESTS
Our research is focused on understanding the molecular mechanisms which drive epilepsy development following epilepsy-inciting events.
Our research is designed to answer three critical difficulties faced by clinicians and researchers in epilepsy.
Arm 1; Firstly we do not fully understand the mechanisms by which an epilepsy-inciting event causes epilepsy. Towards this end we are studying the immediate and persistent epigenetic and epitranscriptomic changes which take place following epilepsy-causing brain insults which eventually reprogram cells to behave differently, culminating in seizures, behavioral changes and cognitive impairment.
Arm 2; Current anti-epileptic drugs are effective at suppressing seizures in about 66% of epilepsy patients. That means about one third of patients are failed by conventional anti-epileptic drugs. Current treatments do not target the molecular basis of the disease. We therefore do not have mechanism based drugs which treat the underlying causes of the disease or have the potential to reverse already established epilepsy. This arm of our research program employs small molecule inhibitors and/or RNA-based antisense or mimic approaches, based on our findings from arm 1, to try to prevent epileptogenesis following an epilepsy-inciting event.
Arm 3; Presently it is not possible to predict with any degree of certainty patients likely to develop epilepsy following a potential epilepsy-causing disease. We are thus attempting to define molecular signatures in peripheral biofluids such as blood plasma which may predict a likelihood of developing epilepsy. This would allow immediate treatment and in future prevention-based therapies to block epileptogenesis.
Research Interests: neuroinflammation; neuroimmunology; neurodegeneration; learning, memory and executive brain function.
Dr. Haase’s research group is interested in the regulation of neurotransmitter systems under physiological and pathological conditions, with a particular focus on the serotonergic system and its relevance to mood disorders as well as the mechanism of action of antidepressant drugs and psychostimulants. The group has been studying various aspects of serotonin transporter (SERT) regulation, primarily the identification and characterisation of SERT interacting proteins using conventional and proteomics approaches. More recently, using animal models of human disease, the research group has been focussing on the regulation of SERT in response to immune system activation.
