Dr Claudia Ntsapi
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.

Capturing 51 giraffes without any injuries or mortalities to collect data that will contribute to the conservation of these animals is not for everyone. Capturing a giraffe with minimum risk to the animal and the people involved, requires extraordinary skill, planning, and teamwork. “This exercise is a dangerous task, since a well-placed kick from these large and extremely powerful animals can cause serious injuries. Early in October was the first time that giraffes were captured on such a large scale,” said wildlife researcher Dr Francois Deacon.
 
Dr Deacon from the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State (UFS), led a multispecialist research group of over 30 people from 10 different countries to collect information about these little-known animals.

UFS first to collar giraffe
Taking a global approach, the team responsible for this intricate process consisted of wildlife biologists, conservationists, interdisciplinary scientists and five specialist veterinarians who are experienced in catching and working with wild animals. Specialised drugs sponsored by Dr Kobus Raath from Wildlife Pharmaceuticals, tested for the first time and administered with a dart gun were used to tranquillise the giraffe, which then allowed for the GPS collars to be fitted.  These collars, sponsored by Africa Wildlife Tracking, enable the researchers to record the location of individual giraffe for up to two years, give 24/7 readings, irrespective of weather conditions. In this cost-effective manner, data can be gathered on climatic factors, giraffe communication, social behaviour, home ranges, seasonal movements, human and giraffe interaction zones, as well as migration routes and the duration of the migration process. The collars will effectively be used to locate individuals to collect faecal samples for hormonal cycles, stress hormones, nutrient deficiencies based on diet and also internal parasites. 

“This knowledge we gain is the key to all keys in saving this iconic animal from becoming extinct,” said Dr Deacon.

Six years ago, during a pilot study, Dr Deacon was the first researcher to fit giraffes with a GPS collar. Collaring is less invasive and allows researchers to collect detailed samples. Not only was extensive knowledge and experience gained during the process, but he also initiated interest from the filmmaker and conservationist, Ashley Scott Davison, executive producer of Iniosante Inc. 

Getting to tell the story

Davison, who was doing research for a film on giraffe learnt about the silent extinction of the species. In a great number of countries giraffe numbers have been declining by as much as 40% over only a few years since 2000. Today West Africa has between 400 to 600 giraffe left while four out of five giraffes were lost in East Africa since 2000. This is a considerable decline in numbers and poses a real threat to the survival of the species in the longer term. At the end of 2016, the giraffe was classified as vulnerable on the International Union for Conservation of Nature Red Data list.

According to Davison, children in school learn about the destruction caused by ivory poaching and habitat loss. But in Africa today, there are six times as many elephants as there are giraffes. 

In the process to find out more about this majestic species Davison learnt of Dr Deacon’s work. After being introduced to and spending time with Dr Deacon, Davison not only describes the UFS as the leader in the conservation of giraffes but he returned to the university, three times to help build a dedicated research team to address unanswered research questions within various disciplines.

Flowing from the affiliation with the UFS is Iniosante’s award-winning production of a documentary, “Last of the Longnecks”. The film has received several awards, including official selection at the 2017 Global Peace Film Festival, the Wildlife Conservation Film Festival and the Environmental Film Festival in the US capital. 

The film team accompanied the multispecialist research team last week to gather footage for a follow-up documentary, “Catching Giants”. This film is expected to air in middle 2018.
