Role of sleep-related brain activity in clearing toxic proteins and preventing Alzheimer s disease

This neuronal activity was more strongly linked with cerebrospinal fluid flow in healthy controls than higher risk groups and patients, and the findings could serve as a potential imaging marker for clinicians in evaluating patients. The development of Alzheimer s disease is believed to be driven by the buildup of the toxic proteins amyloid-β and tau in the brain. The brain s glymphatic system plays a crucial role in clearing these toxins and previous work has shown a possible relationship between sleep-dependent global brain activity and the glymphatic system by showing this activity is coupled by cerebrospinal fluid f

Monitoring the potency of cell therapies using bioelectronic assays

Monitoring the potency of cell therapies using bioelectronic assays 2 Chimeric antigen receptor (CAR) T and natural killer (NK) therapies may become the future of cancer treatment. Dr Jim Ross explains how bioelectronic assays are a non-invasive, label-free approach built for real-time, dynamic assessment of cell therapy potency. Personalised medicine is now within reach for thousands of cancer patients thanks to immunotherapies such as CAR T cells. This cell therapy involves training a patient’s immune system through genetic engineering to recognise tumour cells as foreign bodies and attack them directly, without attacking healthy tissue. In 2017, the US Food and Drug Administration (FDA) approved Kymriah, the first CAR T-cell therapy, for the treatment of B-cell acute lymphoblastic leukaemia. Now, patients across the US can access the treatment at any one of over 130 treatment centers.
