Prosetta Biosciences Inc. has presented data on small molecules that inhibit cellular host factors needed for viral replication as a discovery tool to identify molecular interfaces upstream of Alzheimer’s disease cellular pathology.

It has been previously demonstrated that genetic loss-of-function of triggering receptor expressed on myeloid cells 2 (TREM2) impairs microglia migration, with the TREM2 R47H variant having been linked to increased risk of Alzheimer’s disease (AD) due to impaired microglia clustering and enhanced neuronal damage.

At first glance, the number of drugs that received accelerated approval from the U.S. FDA’s Center for Drug Evaluation and Research (CDER) in 2023 was nothing to write home about. Yes, CDER granted nine accelerated approvals last year, up from six in 2022. But the proportion of novel drugs with accelerated approval was 16% both years. And when compared with the 12 drugs in 2020 and the 14 that received accelerated approval in 2021, last year’s crop was a little lackluster. However, a deeper look at the 2023 class of accelerated approvals shows a historic milestone. For the first time since the path was created in 1992, the number of novel biologics getting accelerated approval at CDER outpaced the number of small-molecule drugs.

Recent studies have identified HAVCR2, which encodes immune checkpoint molecule TIM-3 (T-cell immunoglobulin mucin receptor 3), as a risk gene for late-onset Alzheimer’s disease (AD).

Deep molecular profiling of cell types in the brain is needed to uncover the mechanisms behind neurodegeneration.

Alterations in mitochondrial dynamics are hallmarks of Parkinson’s disease (PD) and other neurodegenerative disorders such as Alzheimer’s disease (AD).

Advances in understanding the processes underlying brain neurodegeneration have allowed lots of new treatment and prevention strategies to begin to flourish. Several presentations at the 2024 Alzheimer’s & Parkinson’s Diseases Conference recently held in Lisbon reflect that eyes are now on some individuals who, despite showing pathological signs in their brains, stay cognitively healthy across several endogenous mechanisms of resilience.

In a new study, researchers from Harvard Medical School and Regulus Therapeutics Inc. further investigated the role of miR-155 in Alzheimer's disease (AD).
