At an RNA metabolism meeting, scientists reported connections between C9ORF72 loss and gain of function. Their talks brimmed with new biology implicating autophagy, the cellular stress response, and RAN translation off introns.
Swine that express mutated human SOD1 exhibit the hallmarks of ALS pathology, including aggregates and degeneration in motor neurons, preceded by a lengthy preclinical phase.
FDG PET revealed the formation of a new functional brain network. It explains clinical improvements noted previously.
In mice, a daily low dose restored regulatory T cells and held off symptoms of a demyelinating disease. Could an old, over-the-counter drug help with ALS, in which similar cells decline?
The Food and Drug Administration has said it will accept cognition alone as the basis for approval in preclinical AD. Now what? Industry is confronting the challenge to show robust and meaningful change.
In sporadic and familial forms of AD, progranulin climbs in the cerebrospinal fluid as disease progresses, perhaps reflecting microglial activation.
In a new take on mosaicism and Alzheimer’s, scientists claim that APP mRNAs convert into DNA and reinsert into the genome. Full of mutations, these “genomic cDNAs” crop up in aging and sporadic AD.
At CTAD, researchers discussed baseline data from the first 500 participants in the EPAD cohort and, finally, the start of recruitment for TRC-PAD.
At CTAD, intranasal insulin trial stumbles, pioglitazone gets a postmortem, a RAGE inhibitor tries to hang on.
In Barcelona, data ran the gamut from a few hopeful little hints on new treatments to mixed signals on familiar players, and failed drugs thrown on the scrap heap.
Researchers are applying the proposed 2018 NIA-AA diagnostic criteria to three large, standing cohorts. How did the research framework perform?
Cultured sensory neurons from ALS mouse models have truncated, less-complex neurites that grow slowly compared to controls.
People with a lot of neurofilament light protein in their spinal fluid are more likely to develop mild cognitive impairment in the next four years.
Large IDEAS data set establishes that PET scans are valuable in clinical practice. Other studies suggest CSF biomarker ratios perform nearly as well.
Scientists at CTAD were excited about postmortem validation of tau scans and new, more sensitive tracers. Others are exploring practical applications for live imaging of tau pathology.
