Coulson Lab - Neurotrophin biology

My lab is currently focusing on the reasons why cholinergic neurons of the basal forebrain die in Alzheimer’s disease, what contribution their loss makes to cognitive decline and whether manipulating neurotrophic signalling  (NGF, BDNF, TrkA/B, p75) can protect or restore cognitive function, and what role the neurotrophins play in the normal function of these neurons.

The lab is supported by:

  • National Health and Medical Research Council of Australia (NHMRC)
  • Alzheimer’s Research UK
  • Motor Neuron Disease Research Institute of Australia (MNDRI)
  • Clem Jones Centre for Aging Dementia Research (CJCADR)
  • Mason Foundation (Perpetual Trustees)

We are currently recruiting mid-year Honours and Masters placement students for projects relating to Alzheimer’s Disease, including those mentioned below. Please send your CV to Bree Rumballe b.rumballe@uq.edu.au for review.

  • Project 1: The role of cleavage of p75 neurotrophin receptor in neurotrophic function (cell biology)
  • Project 2: The role of neurotrophins in regulating the synaptic function of cholinergic basal forebrain neurons (mouse studies: electrophysiology, behaviour, fMRI, in vivo genetic manipulation)
  • Project 3: Studying basal forebrain function in Alzheimer’s disease and sleep apnea (human MRI and PET analysis)
  • Project 4: Developing optimised peptides for treating neurotrophic dysfunction in neurodegenerative disease (biochemistry)
