A preclinical study by neuroscientists indicates that an antigen-presenting dendritic vaccine with a specific antibody response to oligomeric A-beta may be safer and offer clinical benefit in treating Alzheimer’s disease. The vaccine uses immune cells known as dendritic cells loaded with a modified A beta peptide as the antigen.

New generation CRISPR technology lays foundation for therapeutics to treat a wide range of inherited ocular diseases. A breakthrough study, led by researchers from the University of California, Irvine, results in the restoration of retinal and visual functions of mice models suffering from inherited retinal disease.

Published today in Nature Biomedical Engineering, the paper, titled, “Restoration of visual function in adult mice with an inherited retinal disease via adenine base editing,” illustrates the use of a new generation CRISPR...

Multidrug resistance (MDR) — a process in which tumors become resistant to multiple medicines — is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers reporting in ACS’ Nano Letters have developed nanoparticles that release bursts of calcium inside tumor cells, inhibiting drug pumps and reversing MDR.

A pump protein called P-glycoprotein (P-gp) often plays a key role in MDR. P-gp is in the cell membrane, where it uses energy in the form of adenosine triphosphate (ATP) to pump drugs out of tumor cells...

A new study published in Current Biology identifies the biological triggers that promote quicker nerve regeneration. From their previous studies, the researchers knew that damaged nerves regrow more quickly when “stress granules” in the site of the nerve injury are broken apart. Now they know what causes those stress granules to disassemble through a process called protein phosphorylation.

“The important thing is that we identified the protein that drives that process and showed how that’s regulated,” Jeff Twiss, a UofSC biology professor and co-author on the paper, said.

“It actually opens something new,” Pabitra Sahoo, the paper’s lead author, said...
