Dr Matlakala C Ntsapi is a Senior Lecturer and researcher in the Department of Basic Medical Sciences at the UFS.

A researcher from the University of the Free State (UFS) is investigating the potential benefits of medicinal plants as supplementary treatments for neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Huntington’s diseases.

The work of Dr Matlakala Claudia Ntsapi, Senior Lecturer in the Department of Basic Medical Sciences at the UFS, focuses on preserving human brain health to delay or prevent age-related conditions.

According to her, while the primary focus is on age-related neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s, the bioactive compounds in these medicinal plants may also have therapeutic potential for other neurological disorders, various types of cancers and Type 2 Diabetes. The broad protective effects of these plant-based bioactive compounds could make them relevant in the potential treatment of other diseases involving oxidative stress and inflammation.

She is involved in several multidisciplinary projects, collaborating with research experts from Denmark, the UK, and various national institutions such as the Central University of Technology (CUT), North West University (NWU), and the Stellenbosch University (SUN), as well as colleagues from the UFS. 

The potential of medicinal plants

“In collaboration with experts from our institution, the CUT and SU, who have strong backgrounds in pharmacology and ethnobotany, we are focusing on underexplored medicinal plants and nutraceuticals. These plants contain bioactive compounds with potential neuroprotective properties, which are believed to provide extra health benefits beyond basic nutritional value,” says Dr Ntsapi.

“We hope that these medicinal plants have the potential to preserve cognitive function and slow the progression of neurodegenerative diseases like Alzheimer’s. Specifically, we aim to identify novel therapeutic targets and discover new avenues for intervention that can improve the quality of life for individuals affected by age-related brain conditions,” she says.

Identifying therapeutic targets and discovering new interventions

The bioactive compounds found in selective medicinal plants and nutraceuticals, explains Dr Ntsapi, serve as a promising source of ‘natural’ therapeutics that may be safer and have fewer side effects compared to conventional synthetic drugs. Additionally, the untapped potential of these compounds for neuroprotection and the preservation of brain health could provide innovative therapeutic solutions. These compounds may be used as complementary therapies to existing drugs, which often have limited efficacy on their own, thereby enhancing overall treatment outcomes for neurodegenerative diseases.

“By utilising cutting-edge techniques, such the innovative CelVivo ClinoStar 2 System, we strive to gain insights into the safety and efficacy of underexplored medicinal plants in preserving cognitive function and slowing disease progression.

“By exploring the untapped potential of bioactive compounds found in medicinal plants and nutraceuticals, our research group aims to contribute to the identification of novel therapeutic targets and the discovery of new avenues for intervention to improve the quality of life for individuals affected by age-related brain conditions,” says Dr Ntsapi.

The researchers, in collaboration with others in the UFS School of Clinical Medicine, will develop 3D cell-based models of the human cortex and hippocampus by utilising the CelVivo ClinoStar 2 System. This cutting-edge technology, housed in an easy-to-use CO² incubator, mimics ‘animal model-like’ conditions with low sheer stress, allowing scientists to generate cell-based models that closely resemble real-world conditions.

Dr Ntsapi explains that they will specifically focus on the technologies’ applications in studying age-related neurodegenerative disorders, such as Alzheimer’s disease. The potential impact of this research is immense, as it could contribute to the development of novel therapeutic strategies for combating the debilitating progression of neurodegenerative diseases, and ultimately improving the quality of life for affected individuals.

Hope for the research

“Our hope for this research is to significantly advance our understanding of neurodegenerative disease progression and to develop novel therapeutic strategies that can effectively combat these debilitating conditions. Ultimately, we aim to improve the quality of life for individuals affected by neurodegenerative diseases by preserving cognitive function and slowing disease progression.

“This research will contribute to the knowledge pool in this field, with the potential to lead to groundbreaking discoveries in the treatment of Alzheimer’s disease and other related disorders, potentially contributing to the policy guidelines on how these conditions are managed and treated,” she says.

The international partners from Denmark and the UK have made their expertise and facilities available to postgraduate students from the UFS, some of whom they are co-supervising.

Dr Ntsapi, who is passionate about exploring innovative solutions to address the gradual decline in normal brain function associated with aging, was this year one the university’s nominations for the prestigious 2023/2024 NSTF-South32 Awards, popularly known as the “Science Oscars” of South Africa.

Plant-strengthening agent a result of joint effort between UFS and German company
2015-07-27

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.

The application of a plant-strengthening agent in the agricultural industry has, until recently, been largely ignored, says Dr Elmarie van der Watt of the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS). The agent was co-developed by researchers at the UFS and a German company.

The product is moving into new markets, such as China, Vietnam, the USA, and Australia.

ComCat® was the result of extensive research by the German company Agraforum AG. Commercialisation was limited initially to Europe, while research was expanded to other parts of the world, with the University of the Free State as the main research centre.  ComCat® is a unique, non-toxic plant strengthening agent derived from wild plants. It enhances plant growth and yield, as well as resistance against abiotic and biotic stress factors.

Dr Van der Watt says that, in nature, plants communicate and interact by means of allelochemicals (the inherent silent tool of self-protection among plants) and other phytochemicals (chemical compounds that occur naturally in plants), as part of their resistance mechanisms towards biotic and abiotic stress conditions.

Most wild-plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent. “Active compounds contained in extracts from wild plants applied to monoculture crops can potentially supply the signal for the latter to activate their dormant resistance mechanisms.” 

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.  A major advantage is that, despite its enhancing effects on root development and yield, it does not induce unwanted early vegetative growth that could jeopardise the final yield, as happened in the past for nitrogen application at an early growth stage. 

Dr Van der Watt says, “Physiological data on the effect of the natural bio-stimulant product on photosynthesis, respiration, and resistance towards biotic stress conditions indicate that it can be regarded as a useful tool to manipulate agricultural crops. Research also showed that the field of application for this natural product is never-ending, and new applications are being investigated every day.”
