Bioarctic AB has entered into a research and collaboration agreement with Eli Lilly and Co. on a new treatment in the field of neurodegeneration. The collaboration will see Bioarctic generate a new drug candidate combining its Braintransporter technology with an undisclosed Lilly molecule.

Elixiron Immunotherapeutics Inc. announced positive interim open-label phase II Alzheimer’s disease (AD) study findings of enrupatinib, an oral brain-penetrant colony-stimulating factor 1 receptor inhibitor, with plans to move the asset into a biomarker-based and placebo-controlled study.

Parkinson’s disease (PD) involves the progressive loss of dopaminergic neurons, particularly in the substantia nigra. This neurodegeneration is linked to the abnormal accumulation of α-synuclein, a protein that forms toxic aggregates and spreads between cells, damaging them. At the 20th International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD), held from March 17 to 21, 2026, in Copenhagen, several strategies were presented that aim to modify the course of the disease and offer real alternatives to purely symptomatic treatments.

Researchers at INSERM and collaborators have identified hypothalamic tanycytes as mediators of tau clearance and shown that their structural and genetic disruption may drive Alzheimer’s disease pathology.

Researchers at INSERM and collaborators have identified hypothalamic tanycytes as mediators of tau clearance and shown that their structural and genetic disruption may drive Alzheimer’s disease (AD) pathology. AD is characterized by the buildup of extracellular amyloid-β plaques and intracellular tau tangles, protein aggregates that disrupt neuronal function and drive neurodegeneration.

Antiretroviral therapies against HIV have been in use for more than 30 years and have enabled people living with HIV to maintain undetectable viral levels. Many of them are aging in good health. However, others present symptoms of cognitive decline. HIV can reach the brain and establish a reservoir there. Yet, it is still unknown what this reservoir is like, which cells are affected, and which comorbidities are typical of aging or are associated with the virus.

Parkinson’s disease is a neurodegenerative disorder that affects movement, and tremor is one of its signatures. But it is a much more wide-ranging disorder, and patients experience problems with cognitive and emotional processes as well. SCAN, the somato-cognitive action network identified in 2023, could reshape the definition of PD. Treating this circuit can improve outcomes.
