Just last month, we shared some neuroblastoma research using our Primary Human Neurons (cat. HNC001). Well, it didn't take long for our neurons to remind us about their extensive abilities and get back in the spotlight.

Earlier this month, researchers at the University of Maryland School of Medicine released preliminary findings demonstrating a link between COVID-19 and Alzheimer’s disease. Using human primary neurons provided by Neuromics, the investigators infected the cells with SARS-CoV-2 and saw the infection created an Alzheimer's-like neuropathology in the formerly healthy neurons.

Cellular A aggregation (top row) and cellular p-Tau deposition (bottom row). AB Aggregate and p-Tau accumulation in the cytoplasm or neuronal axon are indicated by white arrowheads. Scale bar, 50 µm."

This effect on primary neurons translated to other donor neuron tissues as well, with the scientists continuing to find an Alzheimer’s-like neuropathology in healthy individuals and an aggravated Alzheimer’s neuropathology in Alzheimer’s patients. We encourage you to check out the full publication here.

These new findings remind us that there is still much unknown about the COVID-19 virus, especially how it infects the brain and passes through the blood-brain barrier. However, it is incredible to see our reagents helping answer some of those questions

We encourage you to check out all publications using our primary neurons along with the many publications using the rest of our human cells.
