Microglia play a major role in the pathophysiology of Parkinson's disease, where they regulate both α-synuclein (αSyn) aggregate clearance and inflammatory responses. Interferon gamma (IFNγ) is a strong immunomodulator, but its role in shaping human microglial phenotypes during αSyn exposure remains incompletely understood. Further, whether the secreted factors from microglia after exposure to αSyn pre-formed fibrils (PFFs) and IFNγ can affect morphology and functionality of dopamine neurons has...

Delirium is a common and severe neuropsychiatric syndrome with lasting cognitive consequences, yet its pathophysiology remains poorly understood. We hypothesize that impaired glymphatic flow represents a central mechanism by which delirium evolves. This hypothesis builds on recent evidence showing that major delirium risk factors, such as ageing, dementia, cardiovascular disease and renal failure, are all associated with reduced glymphatic clearance. Similarly, common delirium triggers,...

Sex differences in immune function arise from sex chromosome complement, which drives differential expression and activity of X-linked genes in immune cells, and gonadal steroids that transcriptionally regulate innate and adaptive immune cells through their respective receptors. These fundamental differences shape divergent outcomes between male and female individuals in viral and bacterial infections, post-acute infection syndromes and vaccine responses throughout the lifespan. Understanding...
