Background: Vaxxinity is developing an active immunotherapy targeting Tau for Alzheimer's disease (AD) and other tauopathies. VXX-301 is a multi-epitope vaccine designed to target the N-terminal and repeat domains of Tau. This design enables targeting multiple forms of Tau thought to contribute to Tau associated pathologies.

The role of Natural Killer (NK) cells of the innate immune system in AD has largely been overlooked. In a murine model, depletion of NK cells augmented the accumulation of pathological α-syn.
View Article and Find Full Text PDFBackground: In the brain as in other organs, complement contributes to immune defence and housekeeping to maintain homeostasis. Sources of complement may include local production by brain cells and influx from the periphery, the latter severely restricted by the blood brain barrier (BBB) in healthy brain. Dysregulation of complement leads to excessive inflammation, direct damage to self-cells and propagation of injury.

Background: Pathological tau accumulation is the primary constituent of neurofibrillary tangles and other tau aggregates seen in various neurodegenerative diseases collectively known as tauopathies. Recently, immunotherapeutic strategies focused on tau have shown promise in reducing tauopathy in both cellular and animal models.
Method: We previously used humanized yeast models to purify recombinant hyper-phosphorylated human Tau for mouse immunizations and the isolation of a high-affinity anti-Tau monoclonal antibody (mAb) with enhanced diagnostic and prognostic capacities.
Background: Evidence suggests glucagon-like peptide 1 receptor agonists (GLP-1RAs) may have therapeutic potential in Alzheimer's disease (AD). Cumulative evidence has indicated a potential reduction in cognitive decline in people with AD, while real-world evidence has shown decreased dementia risk in patients with type 2 diabetes. Non-clinical data reveal that GLP-1RAs impact neuroinflammation and other biological processes believed to be involved in AD pathophysiology, including effects on central and peripheral immune cells.
