To determine the role of C3a-C3a receptor signalling in ischaemia-induced neural plasticity, we subjected C3a receptor-deficient mice, GFAP-C3a transgenic mice expressing biologically active C3a in the central nervous system, and their respective wild-type controls to photothrombotic stroke. We found that C3a overexpression increased, whereas C3a receptor deficiency decreased post-stroke expression of GAP43 (P < 0.01), a marker of axonal sprouting and plasticity, in the peri-infarct cortex. To verify the translational potential of these findings, we used a pharmacological approach. Daily intranasal treatment of wild-type mice with C3a beginning 7 days after stroke induction robustly increased synaptic density (P < 0.01) and expression of GAP43 in peri-infarct cortex (P < 0.05). Importantly, the C3a treatment led to faster and more complete recovery of forepaw motor function (P < 0.05). We conclude that C3a-C3a receptor signalling stimulates post-ischaemic neural plasticity and intranasal treatment with C3a receptor agonists is an attractive approach to improve functional recovery after ischaemic brain injury.]]> Wed 17 Nov 2021 16:30:36 AEDT ]]> Neurofilament light chain (Nfl) in blood—a biomarker predicting unfavourable outcome in the acute phase and improvement in the late phase after stroke https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50139 Wed 05 Jul 2023 12:54:49 AEST ]]> Plasma neurofilament light chain levels predict improvement in late phase after stroke https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49081 Wed 03 May 2023 16:22:13 AEST ]]> Reactive astrocytes prevent maladaptive plasticity after ischemic stroke https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47354 Fri 13 Jan 2023 13:20:00 AEDT ]]> Astrocyte Responses to Complement Peptide C3a are Highly Context-Dependent https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51514 Fri 08 Sep 2023 12:03:44 AEST ]]>
