Using human iPSC-derived cortical neurons for the early prediction of neurotoxicity

Using human iPSC-derived cortical neurons for the early prediction of neurotoxicity

All pharmaceutical development programs carry a certain amount of risk. However, when it comes to developing drugs that target the central nervous system, the odds of success narrow significantly.

The rise of hiPSC-Derived Motor Neurons as a physiologically relevant model for drug discovery

The rise of hiPSC-Derived Motor Neurons as a physiologically relevant model for drug discovery

Amyotrophic Lateral Sclerosis (ALS), a Motor Neuron Disease (MND) subtype, is a debilitating neurodegenerative disorder affecting the upper and lower motor neurons (UMNs/LMNs), brain stem and spinal cord. This leads to progressive muscular weakness and atrophy, paralysis, and eventually death, usually within three to five years after the onset of symptoms. Decades of failed drug development mean that MND/ALS is still incurable; only two FDA-approved drugs exist (riluzole, and more recently, edaravone), but these only slow down disease progression.

Human iPSC-Derived Motor Neurons: Expert tips on best cell-culture practices to enhance your research

Despite intensive research, there is still no known cure or standard treatment for Amyotrophic Lateral Sclerosis (ALS), a Motor Neuron Disease (MND) subtype. Researchers have traditionally used animal models (usually mice) to screen candidate compounds, but these models are now known to lack physiological relevance to the human pathology, which could limit translational drug development.

Using human iPSC-Derived Renal Cells to enhance safety toxicity testing during drug development

Using human iPSC-Derived Renal Cells to enhance safety toxicity testing during drug development

Kidneys play a key role in removing waste and toxins from the body, as well as having essential endocrinological and homeostatic functions. If certain pharmaceuticals are abused, administered incorrectly or taken regularly, they can induce toxicity in the kidneys (nephrotoxicity). This can result in impaired renal function, and even death in the most severe cases. For example, nephrotoxic drugs (NDs) are responsible for 19-25% of acute kidney injury in critically ill patients.

Enhancing Amyotrophic Lateral Sclerosis (ALS) drug discovery using physiologically relevant hiPSC-Derived Motor Neurons

Enhancing Amyotrophic Lateral Sclerosis (ALS) drug discovery using physiologically relevant hiPSC-Derived Motor Neurons

Amyotrophic Lateral Sclerosis (ALS), a Motor Neurone Disease (MND) subtype is characterised by the degeneration and death of nerves (motor neurons) in the brain and the spinal cord that control essential voluntary muscle activity. Affecting over 400,000 patients worldwide each year, MND/ALS progressively causes difficulties in speaking, walking, breathing, and swallowing, with the disease eventually being fatal in about a quarter of all patients affected each year.

Guest Post: Are 3D neural cell cultures the best translational models towards finding a cure for Alzheimer's disease?

Guest Post: Are 3D neural cell cultures the best translational models towards finding a cure for Alzheimer's disease?

Diagnosed by the German psychiatrist and neuropathologist, Dr. Alois Alzheimer in 1906, Alzheimer’s disease (AD) is the most prevalent form of dementia in the ageing population (Korolev et al., 2014). Recently declared as the sixth major cause of death in the world; patients affected with AD suffer a gradual decline of cognitive abilities and memory functions till the disease renders them incapable of performing daily activities. Some of these traits, which are typical of neurodegenerative diseases are also shared by other forms of dementia.

Guest Post: Using neural stem cells for safety pharmacology studies

The brain is the most complex organ in the body, controlling our highest functions, as well as regulating myriad processes which incorporate the entire physiological system. There is a significant risk that a novel therapeutic agent might impact brain structure and function, resulting in serious pathologies and even death. Therefore, CNS testing forms part of the 'core battery' of safety pharmacology studies .

Macrophages and the immune system: the role of microglia in immunity and neurodegenerative disease

Macrophages and the immune system: the role of microglia in immunity and neurodegenerative disease

The body’s immune system is our first line of defence against foreign substances, protecting us against infection and disease. It consists of a complex network of organs and cells that work to recognize and destroy these harmful substances, containing them at the site of infection. Macrophages play a crucial role in this; engulfing and destroying anything dangerous via phagocytosis.

Tracing the journey of monocytes to macrophages: what does it mean for your research?

Tracing the journey of monocytes to macrophages: what does it mean for your research?

The human immune response consists of a complex network of cells working together to identify and destroy foreign substances in the body. Two key players in this response mechanism are: 1) circulating peripheral blood monocytes, the cells first to the site of interest; and 2) macrophages, which arise at the point of injury or infection through differentiation of these monocytes into tissue-specific macrophages. Macrophages are responsible for destroying the foreign body before further infection occurs.

Why make the switch from animal cells to human iPSC-Derived Sensory Neurons?

Why make the switch from animal cells to human iPSC-Derived Sensory Neurons?

Millions of people around the world suffer from debilitating pain. However, with impressive advances being made in pain research and drug discovery efforts, researchers are continuing to delve deeper into the molecular pathways underpinning pain, to ultimately improve both the screening of drug candidates and the quality of life for people across the world.

Expert tips on culturing human iPSC-Derived Sensory Neurons to aid your research

Innovations in biotechnology and advances in stem cell biology are currently revolutionizing biomedical research and drug discovery. One exciting breakthrough has been the ability to produce sensory neurons from human induced pluripotent stem cells (hiPSCs) and culture them in vitro on multi-electrode array (MEA) systems, to advance pain research and the discovery of effective pain therapies.

How can human iPSC-Derived Sensory Neurons transform your pain research?

How can human iPSC-Derived Sensory Neurons transform your pain research?

Millions of people around the world suffer from debilitating pain, causing immense suffering and reducing their quality of life. With the economic costs of chronic pain estimated to be up to $635 billion each year in the US alone , it’s crucial for scientists to be able to fully understand the functionality of human sensory neurons and how they respond to potential new drugs. In the race to find effective treatments, scientists commonly study in vitro neuron cultures to characterize the molecular pathways underlying pain, which can help to identify therapeutic targets and quickly screen potential drug candidates.

A suffering relationship in Alzheimer's disease

A suffering relationship in Alzheimer's disease

Age, diabetes and having the two copies of the gene for apolipoprotein E 4 (APOE ε4) are just some of the factors that significantly increase the chance of developing Alzheimer’s disease later on in life. Associate Professor Carmela Matrone’s research group used stem cells generated from Alzheimer’s disease patients with the APOE ε4 gene to show that this genetic risk factor is connected to a deterioration of a relationship between two key proteins, sortilin-related receptor (SORL1) and amyloid precursor protein (APP) 1 .
