To comprehensively characterize complement pathway activation in chronic inflammatory demyelinating polyneuropathy (CIDP) and its association with clinical disease features using advanced complement profiling.Complement protein levels indicative of classical, lectin, and alternative pathway activation were quantified by multiplex ELISA and compared between 28 patients with typical CIDP, 24 patients with Charcot-Marie Tooth neuropathy (CMT), and 24 demographically matched healthy controls (HD).Serum levels of activated complement proteins-C3a, C4a, Ba, Bb, C5a, and the soluble terminal complement complex sC5b-9 (sTCC)-were significantly elevated in CIDP patients compared to healthy donors (HD) (p < 0.001). Except for C3a, these protein levels were also significantly higher in CIDP patients than in those with Charcot-Marie-Tooth disease (CMT). [...]

Severe optic neuritis (ON) is a common clinical manifestation in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and neuromyelitis optica spectrum disorder (NMOSD). Given distinct prognoses and often the necessity of early plasma exchange in NMOSD, prompt differentiation is crucial. [...]

Down syndrome (DS) is a genetic cause of Alzheimer's disease (AD), with virtually all individuals developing AD pathology by their fourth decade due to Amyloid Precursor Protein (APP) gene overexpression. In addition to amyloid beta (Aβ) plaques and hyperphosphorylated tau (p-Tau) aggregates, DS-associated AD (DSAD) often includes α-synuclein (αSyn) aggregates, contributing to Lewy body pathology (LBP). [...]

Background:High-resolution (7T) MRI facilitates in vivo imaging of fine anatomical structures selectively affected in Alzheimer's disease (AD), including medial temporal lobe subregions. However, 7T data is challenging to acquire and largely unavailable in clinical settings. [...]

The nucleus basalis of Meynert (NBM) is crucial for learning, attention, and memory. While its involvement in Alzheimer's disease (AD) has been widely reported, the role in frontotemporal dementia (FTD) remains unclear. [...]

Background: The basal forebrain (BF), home to cholinergic neurons essential for attention and memory undergoes structural changes in sporadic Alzheimer's Disease and in at-risk individuals, contributing to cognitive decline. To investigate whether BF volume is reduced in preclinical autosomal-dominant Alzheimer's disease (ADAD), we studied cognitively-unimpaired carriers of the PSEN1 E280A mutation from the Colombian kindred, the largest ADAD cohort with a single mutation, known for early cognitive decline (mild cognitive impairment at age 44, dementia at 49). [...]

With the approval of anti-amyloid therapies in Alzheimer's disease (AD), surrogate biomarkers are urgently needed to monitor treatment effects that translate into clinical benefits. Candidate biomarkers, including amyloid-PET, tau-PET, plasma phosphorylated tau (p-tau), and MRI-assessed atrophy, capture core pathophysiological changes in AD. [...]

The prevalence of neurodegenerative diseases (ND), including Alzheimer's disease (AD) and non-AD tauopathies, is projected to rise significantly by 2050 due to an aging global population. Chronic neuroinflammation, driven by glial activation in response to protein pathologies, is a major contributor to disease progression. [...]

Mitochondrial bioenergetics are vital for ATP production and are associated with several diseases, including Parkinson's Disease (PD). Here, we simulated a computational model of mitochondrial ATP production to interrogate mitochondrial bioenergetics under physiological and pathophysiological conditions, and provide a data resource that can be used to interpret mitochondrial bioenergetics experiments. [...]

Neuropsychiatric symptoms are common in Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD), yet their genetic underpinnings remain unclear. To gain insight into biological processes related to neuropsychiatric symptoms in dementia, we investigated whether polygenic risk scores (PRS) for psychiatric disorders - major depressive disorder (MDD), schizophrenia (SCZ), bipolar disorder (BD), and autism spectrum disorder (ASD) - are associated with neuropsychiatric symptoms in dementia.
