The research group

Our research interests are to unravel the mechanisms underlying motor deficits induced by spinal cord injury and brain injury. Injury of the central nervous system usually causes motor deficits at different degrees. The symptoms include, among others, reduced muscle activity, such as paralysis, and/or increased muscle tone, such as hypertonia. Spasticity is a symptom of altered skeletal muscle performance with a combination of paralysis, increased tendon reflex activity, and hypertonia (Wikipedia). So far the mechanisms of pathophysiology of spasticity are not fully understood. They may involve reduced inhibition of motor neurons in the spinal cord from supra spinal sources, increased sensory activity of afferent signals from periphery, and/or plastic changes of spinal network in the spinal cord below the lesion. To understand the mechanisms of its pathogenesis is essential for developing strategies to treat or alleviate this disorder.

Current projects

1. Plasticity of monoamine system in the spinal cord following spinal cord injury: In this project we use different spinal cord injury models, including hemisection, contusion and complete spinal transection models to study plastic changes of monoamine system in the spinal cord. At present our focus is on serotonin and dopamine system, including the transmitter and their receptors. In addition, we will also study intrinsic spinal sensory neurons, including cerebral spinal fluid-contacting neurons, and try to reveal their anatomical distribution and functions at normal and different pathological situations.
2. Mechanisms of hypotension following spinal cord injury: A symptom following spinal cord injury is the lowered blood pressure especially in its acute and subacute phase. Often the patients experience hypotension when the body position is changed – so called orthostatic hypotension. Although there are some hypotheses the exact mechanism is still not clear. We will investigate the mechanism behind this cardiovascular functional change using spinal cord injured animal models.
3. Motor deficits following traumatic brain injury: Traumatic brain injury is a complex injury with a broad spectrum of symptoms and disabilities, which include a variety of physical and psychological effects. The impact on a person and his or her family can be devastating. Motor deficits are commonly seen following traumatic brain injury. One of the physical changes is abnormal posturing, especially when the injury is severe. In an ongoing project in collaboration with Prof. Georgy Bakalkin from Uppsala University and Prof. Jens Schouenborg we try to investigate a spinal mechanism underlying the formation of abnormal posture using a rat model. One of the aims is to find a pharmacotherapy to treat or alleviate abnormal postural symptom induced by brain injury.

Principle investigator

Mengliang Zhang received his education in medicine in China at Jinzhou Medical University from 1981 to 1986.  He obtained his Master degree in neuroanatomy at Dalian Medical University in China in 1991. He got his PhD in neurophysiology at Lund University in Sweden in 2001 under the supervision from Prof. Jonas Broman. From 2001 to 2004 he did a 3-year postdoc at Pennsylvania State University, USA, with Prof. Kevin Alloway, working on neuronal synchronization from sensorimotor cortex. In 2004, as a research associate professor, Mengliang Zhang joined “Motor Control of Movement Group in Copenhagen” at University of Copenhagen directed by Prof. Hans Hultborn, where he worked until 2016. Here he got several research grants independently or collaboratively and developed his own research direction – plasticity of monoamine system in the spinal cord following spinal cord injury. From 2013, as a researcher, Mengliang Zhang also part-timely worked at Neuronano Research Center at Lund University directed by Prof. Jens Schouenborg. He became a reader (docent) in 2017 at Lund University. Mengliang Zhang was recruited as an associate professor in anatomy and neurobiology to the Dept. of Molecular Medicine at the University of Southern Denmark in 2018.
