Solute carriers (SLCs) are specialized transport proteins that control the movement of nutrients, ions and neurotransmitters across cell membranes and are essential for brain metabolism and neuronal communication. While some SLCs have been targeted successfully by drugs for decades, most of this large protein family remains therapeutically unexplored. A new review in Nature Reviews Drug Discovery (DOI: 10.1038/s41573-026-01513-4; impact factor: 91), led by Giulio Superti-Furga, founding scientific director of the Austrian Academy of Sciences (OeAW) institutes CeMM and Cori, highlights the growing potential of SLC transporters as targets for drugs and gene therapies in central nervous system disorders, including epilepsy, autism spectrum disorders, Alzheimer’s disease and Parkinson’s disease.
By delivering short bursts of pink noise in phase with neural slow waves in the brain, Joshua Levitt and colleagues were able to increase the flow of cerebrospinal fluid (CSF) in sleeping adults. Their approach helps confirm that CSF flow can be modulated through slow wave neurofeedback. CSF normally pulses through the brain in waves to help maintain healthy brain function. Disrupted CSF flow has been associated with diseases such as Alzheimer's and Parkinson’s, which has prompted researchers to look for ways to encourage flow. In participants napping in an MRI machine, Levitt et al. first used a neural network technique to time pink noise bursts with the peaks of EEG slow waves detected in the sleepers. The technique increased EEG slow waves, which in turn increased CSF flow waves – but only when the auditory stimuli were aligned with slow wave peaks. The researchers also discovered that the auditory stimulus caused widespread suppression of gray matter blood oxygenation signals, indicating a drop in blood volume. This drop in blood volume may allow for increased CSF flow, the authors suggest. The results “provide a tool for modulating CSF flow that can next be explored in populations with disrupted sleep or CSF flow circulation,” Levitt et al. write.
UNMC researchers have published an article in “Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association” detailing the creation of an animal model that helps resolve questions about the relationship between HIV and Alzheimer’s disease (AD).
The work can serve as a guide for the development of novel therapeutics to halt memory loss antiretroviral drugs have shown strong potential to prevent and slow progression of both HIV and AD. Specific classes of HIV medications suppress brain inflammation and genetic mutations linked to Alzheimer’s pathology.
