Microglial dysfunction is a key pathological feature of Alzheimer´s disease (AD), but little is known about proteome-wide changes in microglia during the course of AD pathogenesis and their consequences for microglial function. Here, we performed an in-depth proteomic characterization of microglia in two AD mouse models, the overexpression APPPS1 and the knock-in AppNL-G-F (APP-KI) model. Proteome changes were followed from pre-deposition to early, middle and advanced stages of amyloid plaque ...

Extracellular vesicles (EVs) are small membrane-derived vesicles that shuttle proteins or nucleic acids between glia and neurons, thereby promoting neuronal survival and plasticity in the CNS. Exosomes are small EVs (40-150 nm) that are derived from multi-vesicular bodies (MVBs) of the endo-lysosomal pathway, formed by inward budding of the limiting membrane into the MVB lumen and released into the extracellular space upon fusion of the MVB with the plasma membrane (PM). Previous research revealed ...

Lewy body (LB) pathology and loss of dopaminergic neurons are imprints of Parkinson’s disease (PD). LBs are mainly comprised of alpha-Synuclein (Dijkstra et al., 2014). Strolling detection of LBs in brain regions contribute to progressive construct of PD pathology to which molecular mechanisms are not clear (H. Braak & Del Tredici, 2017). Two key facets of LB formation are protein aggregation via misfolding and transmission of misfoldled proteins to various brain regions, eventually causing ...

To study mechanisms of neurodegenerative diseases, neuronal cell lines are important model systems and are often differentiated into postmitotic neuron-like cells to resemble more closely primary neurons obtained from brains. One such cell line is the Lund Human Mesencephalic (LUHMES) cell line which can be differentiated into dopamine-like neurons and is frequently used to study mechanisms of Parkinson’s disease (PD) and neurotoxicity. Neuronal differentiation of LUHMES cells is commonly verified ...

To understand how cells communicate with each other, it is essential to define the cellular secretome, a collection of proteins including soluble secreted, unconventionally secreted and proteolytically-shed proteins. Quantitative methodologies to decipher the secretome are challenging, due to the requirement of large cell numbers and abundant serum proteins that interfere with the detection of low-abundant cellular secretome proteins. Here, we have use the highe perfomance ...

Niemann-Pick type C disease is a rare neurodegenerative disorder mainly caused by mutations in Npc1, resulting in abnormal late endosomal/lysosomal lipid storage. Although microgliosis is a prominent pathological feature, direct consequences of NPC1 loss on microglial function remain uncharacterized. Previously, we have characterized microglial proteome alterations in the NPC1 KO mouse model (PXD019447). In order to investigate similar changes in humans, we have cultured monocyte derived macrophages ...
