     summary: Financially supporting journals by national or international funding organizations (such as Gates Open Research) is also not helpful, because funding is usually restricted to a limited period of time, so that permanent structures which are mandatory for scientific journals are endangered. I am deeply convinced that the purpose of scientific journals is publishing science, ideally the best science, but definitely not making money, for whomsoever.

       title: The “neuroepithelial tumor”: Exchanging our trash can for an industrial size dumpster?

     summary: For instance, whereas we previously had only two known NET entities, dysembryoplastic neuroepithelial tumor (DNET) (don’t even get me started on “dysembryoplastic”) and cribriform neuroepithelial tumor (CRINET), we’ve since added: 1) high-grade neuroepithelial tumor (HGNET) with MN1 alteration (HGNET-MN1), 2) HGNET with BCOR exon 15 internal tandem duplication (HGNET-BCOR), 3) neuroepithelial tumor with H3 G34 mutation (NET-H3-G34), and 4) polymorphous low-grade neuroepithelial tumor of the young (PLNTY)3-9. This explains the intended use of neuroepithelial tumor in the original 1988 description of DNET10, wherein the authors emphasized their view that DNET is likely related to a developmental disorder or malformation, given the frequent histologic findings resembling focal cortical dysplasia in adjacent cortex.

     summary: Although originally be-lieved to disturb brain development in the course of intrauterine infection (Counotte et al 2019), it became clear in the last years that it may also infect the adult human nervous system and give rise to inflammatory diseases of the central and peripheral nervous system (da Silva et al 2017). Epstein-Barr Virus specific CD8 T cells selectively infiltrate the brain in multiple sclerosis and interact locally with virus-infected cells: Clue for a virus driven immunopathological mechanism (Serafini et al 2019) Even in the absence of an overt inflammatory disease of the central nervous system there is a small to moderate number of T-lymphocytes present in the brain and spinal cord, while infiltration of the tissue by T-cells and B-cells is massively increased in inflammatory brain diseases.

     summary: Cerebral endothelial cells of these mice also overexpressed Sox2.They limited Sox2 expression in endothelial cells by generating heterozygous Cdh5-cre/Sox2fl/wt mice with endothelial deletion of Sox2 in heterozygosis. In the affected vessels, endothelial cells suffer endothelial-to-mesenchymal transition (EndMT), express stem cell markers, and undergo loss of typical endothelial cell properties, with increased cell migration, reduced adherence, and increased blood-brain barrier (BBB) permeability.

     summary: Fixation time of dura mater samples ranged from 3 to 10 years. This suggests propagation of alpha-synuclein from the brain and may indicate that dura mater could be a potential risk tissue for inadvertent transmission of alpha-synuclein by dura mater grafts or surgery.

     summary: In 2019, this was emphasized by the positive results of a very large clinical trial (CRASH 2019), the use of magnetic resonance imaging (MRI) and subsequent neuropathology correlation in TBI patients (Griffin, Turtzo et al. 2019) and a pre-clinical model of sub-concussive blast exposure in the rat (Gama Sosa, De Gasperi et al. 2019). Fibrinolysis, with increased concentrations of fibrinogen degradation products, is commonly seen in the brains of acute TBI patients and predicts the development of further intracranial hemorrhagic expansion (Zhang, He et al. 2018).

     summary: Autoimmune-prone female non-obese diabetic (NOD) mice immunized with the MOG35-55 peptide consistently induced severe and long-lasting progressive EAE (PEAE) in 100% of animals characterized by paralysis of fore and hind limbs with (Slavin et al., 1998; Hidaka et al., 2014; Dang et al., 2015) or without discernible remissions (Basso et al., 2008; Jayaraman et al., 2017; 2018). Regardless, PEAE induced in NOD mice mimics features of progressive MS including the life-long disease, prominent demyelination, axonal loss, and astrogliosis (Slavin et al., 1998; Basso et al., 2008; Hidaka et al., 2014; Dang et al., 2015; Jayaraman et al., 2017; 2018), and hence is ideal for testing the efficacy of new drugs to treat progressive MS.

This period of full-time research reinforced my passion for investigating brain diseases of which there seemed so many without an effective treatment, in part a consequence of inadequate understanding of the disease process – hardly surprising given the complexity of the nervous system and the difficulty of accessing brain tissue during the course of many of these diseases.

     summary: However, knockout mouse models of C9orf72 do not show neuronal defects but, rather, exhibit an inflammatory phenotype (39-41), although reduction of C9orf72 protein appears to exacerbate phenotypes in mice overexpressing mutant C9orf72 RNA (42). The mutation is associated with a reduction of C9orf72 protein and accumulation of toxic RNA and dipeptide repeat aggregates.

      flesch: 52
     summary: Downregulated proteins included DSP, IDE, HBG1. Conclusions: The present study reports an in-depth quantitative proteomic profiling of white matter from patients with CAA, highlighting extracellular matrix proteins and clusterin as key molecules in the pathophysiology of white matter changes in cases of CAA. Introduction Cerebral amyloid angiopathy (CAA) is characterized by the deposition of amyloid proteins including amyloid beta (Aβ), cystatin C, prion protein, ABri/ADan, transthyretin, gelsolin and immunoglobulin light chain amyloid (1) in the walls of leptomenigeal arteries and cortical arterioles (CAA-Type 2) (2) and in the walls of arteries or capillaries (CAA-Type 1), but rarely in the walls of venules (1-3).

     summary: As we did not observe any area with axonal spheroids to have reactive ramified microglia, it is unlikely that axonal spheroids precede microglia loss. Our results and conclusions in this study (i.e. the correlation between microglia loss and axonal spheroids) are based on the pathological findings only, regardless of the underlying genetic alterations.

     summary: Experimental DSS colitis-induced at a young age exacerbates αSyn brain pathology and dopaminergic neuron loss in old αSyn transgenic mice At this point, we have established and repeatedly demonstrated that modulation of inflammatory mechanisms in experimental colitis induced by acute and chronic DSS administration is causatively linked to induction and persistence of intracellular αSyn inclusions in the ENS of young adult mice. Recently, it was reported that experimental colitis in αSyn transgenic mice leads to enteric accumulation of αSyn and the development of PD-like brain pathology and symptoms within a few months

There appears to be little support for the concept that viral infections are a major contributor to today’s common dementias.

     summary: We propose that antiplatelet agents targeting thromboxane A2 receptor signaling such as low-dose aspirin merit consideration for chemoprophylaxis when administering the adenovirus based COVID-19 vaccines to young adults at risk of thrombosis provided there are no contraindications. B. Predilection of cerebral venous sinuses for thrombosis following vaccination Recent studies have demonstrated that arterial, venous and sinusoidal endothelial cells in the brain uniquely express markers of the lymphatic endothelium including podoplanin.37 Podoplanin (D2-40) serves as a ligand for CLEC2 receptors on platelets.38 Thromboxane A2-dependent CLEC2 signaling leads to platelet activation (Figure 1), while a TxA2 receptor antagonist nearly abolished CLEC2 signaling and platelet activation.38 TxA2-dependent CLEC2 signaling promotes release of exosomes and microvesicles from platelets, leading to activation of CLEC5A and TLR2 receptors respectively on neutrophils, neutrophil activation and release of neutrophil extracellular traps (NETs) (Figure 1).39 Neutrophil activation, more than platelet activation, is associated with thrombotic complications in COVID-19.13,18,40 As proposed above, the expression of podoplanin by cerebral venous sinuses may be responsible for the predilection of brain vascular bed to thromboinflammation and CVST as a complication of COVID-19 vaccines.

To obtain histological confirmation of the CMBs detected by ex vivo MRI, the 1 cm brain slabs were dissected further and MHs or areas corresponding to the CMBs detected by ex vivo MRI were blocked and serially sectioned at 6 μm intervals.

     summary: One difference between human and rodent neuropathology is the age-related accumulation of iron in the brain (Connor et al. 1992, Hametner et al. 2013), which is largely absent in rodents, at least at ages of the animals generally investigated in AD models. Iron accumulation in human microglia is increased in neurodegenerative diseases, and it is associated with a pro-inflammatory activation of the cells (Mehta et al. 2013, Hametner et al. 2013, van Duijn et al. 2017), possibly related to its pro-oxidative function.

     summary: Similarly, clinical AD dementia cases were twice as likely as NI cases to have either single or multiple cerebrovascular lesions (OR 2.24, 1.50 - 3.36, p<0.001). Indeed, several ‘vascular’ risk factors are also AD risk factors and previous studies have suggested that up to 35% of late-life dementia may be preventable by targeting multiple risk factors such as diabetes, hypertension, obesity, smoking, depression, cognitive inactivity, and physical inactivity (1,27,28).

     summary: Many of these cell states mirror the neurodevelopmental hierarchy, and it has been suggested that tumor cells can transition between more or less differentiated states. At the same time, there may be an opportunity for immunohistochemistry here as well: for example, loss of H3K27me3 staining of tumor cell nuclei in meningioma has been reported as an additional tool for identification of meningiomas with higher risk of recurrence 36,37.

     summary: While these results are very promising from the tissue engineering standpoint, it remains to be seen whether a similar approach can be used to promote muscle fiber regeneration in muscle dystrophies and other muscle diseases that show a significant loss of muscle volume. From the muscle pathology perspective, the most recognizable autophagy defect involves inhibition of the bulk autophagic flux, which results in the autophagic vacuolar myopathy (AVM) phenotype; however, defects of autophagy induction and cargo sequestration can also result in muscle disease (Fig. 3).

     summary: Cell Culture To improve our understanding of the interaction of the virus with endothelial cells and furin, cultures of four cell lines were used: human endothelial cells derived from Induced pluripotent stem cells (iPSC-d-ECs), a human cerebral microvessel endothelial cell line (hCMEC/D3), a Human Umbilical Vein Endothelial Cell line (HUVEC) and a primate kidney cell line (Vero E6 cells). While no viral particle or viral RNA was found in the brain, the SARS-CoV-2 spike protein was detected in the Golgi apparatus of brain endothelial cells where it closely associated with furin, a host protease known to play a key role in virus replication.

     summary: Mechanism or associated outcome Role in postmortem brain decomposition Cell death by oncotic necrosis The main cell death pathway in the postmortem brain, wherein the loss of ATP leads to a sequence of morphological changes and eventual necrosis Autolysis Primary role in the early postmortem decomposition of brain cells Apoptosis Not a substantial contributor to postmortem decomposition, because this cell death pathway requires ATP Compacted neurons (a.k.a. dark neurons) May become more common after short periods of PMI, but less common with longer periods of PMI; is not thought to contribute to postmortem decomposition Temporary ischemia Temporary cerebral ischemia followed by reperfusion has much different mechanisms of decomposition (e.g. requiring ATP) than the permanent global cerebral ischemia that occurs postmortem Postmortem fluid shifts Biomolecular breakdown and blood extravasation leads to dramatic fluid shifts in the early postmortem brain; eventually, the brain is transformed to a paste- or fluid-like consistency Perivascular and pericellular rarefactions These areas expand and become more frequent in the PMI, which appears to be due to the swelling of astrocyte processes and other cells, causing those areas to not stain on light microscopy Vacuolization Common finding in postmortem brain cells and tissue spaces such as the neuropil that evolves throughout the PMI and can cause alteration of cell morphometry or compression of other structures Biomolecule degradation Largely driven by enzymes, biomolecule breakdown is a key driving force of postmortem decomposition, varying in rate based on many factors, such as the substrate and the temperature Biomolecule redistribution The breakdown of the factors stabilizing biomolecules in place in vivo leads them to eventually diffuse away from their original locations, with degrees of both Gaussian and non-Gaussian spread Table 1. Many studies describe vacuoles as a characteristic morphologic finding in postmortem brain cells (Haines and Jenkins, 1968; Hilbig et al., 2004; Koenig and Koenig, 1952).

     summary: Importantly, in the year prior the same laboratory published the results from a different experiment in which the artificial brain model was exposed to blast wave; this resulted in an entirely different pattern of tissue distortion with physical strain maximized at interface regions, particularly the subpial region and gray-white matter junction, closely corresponding to the pattern of pathology observed in interface astroglial scarring.8,9 Chronic traumatic encephalopathy is primarily a neuronal disease Debate over how to identify and classify CTE pathology continued in 2022, with a focus being on the relevance of astrocytic ptau pathology in cases of CTE and largely in response to the de-emphasis of astrocytic ptau as necessary for a CTE diagnosis in the most recent consensus diagnostic statement.10 Authors Butler et al., with the resources of the Boston University CTE Brain Bank, examined dorsolateral frontal cortex samples from the brains of 150 decedents with known CTE for the precise cellular distribution of ptau pathology in the cerebral cortex.11 Individuals whose brains were examined in the study ranged from 21 to 80 years of age. Finally, a large-scale analysis of APOE genotypes contends that gene status may influence CTE pathology and outcomes.

Given the demonstrated morphological heterogeneity of mcPXA tumors, this work contributes to providing an alternative for defining PXA on molecular, rather than morphological grounds.

     summary: In concrete terms, when the authors of the WHO endocrine pituitary tumor classification recommend that the complete panel of stains be performed on all pituitary adenomas, they promote a classification system that overfits the data and reduces reproducibility while at the same time generating expensive, wasteful, and distracting false positives and false negatives in laboratories worldwide. While WHO committees do not endorse particular tests, marker co-expression is a fundamental feature of pituitary adenoma classification that needs to be addressed.

     summary: First, affected cerebrospinal tracts show not only diffuse loss of myelin, resulting from moderate loss of myelinated fibers, but also moderate diffuse loss of pNFP-immunoreactive axons (Fig. 1) that seems to be commensurate with myelin loss. Thus the situation is complicated by the mutual dependency between myelin sheath and axon, leading to secondary axonopathies in primary myelinopathies, and vice versa.

     summary: To determine a practical value for p53 immunostaining in everyday neuropathology practice and to validate whether a 10 % cut-off can be reliably used to suggest TP53 mutation (as suggested by WHO 2021), we analyzed a group of diffuse gliomas for p53 staining and TP53 mutations. The median p53 immunohistochemistry labeling index for tumors harboring TP53 mutation was 60 % (Range: 0-95 %) with an interquartile range (IQR) of 66.25 %, while the median value for those without TP53 mutations was 10 % with an IQR of 10.5 % (Range: 0-30 %).

     summary: The suggested model that AD-TLE represent a specific disease subtype needs further validation to confirm the role of hyperphosphorylated tau in epilepsy patients with and without AD considering age and age at epilepsy onset as potential moderator variables. Twenty-nine cases were previously published with a diagnosis of FCD Type 1, mMCD or non-lesional, which needs reconsideration and which also highlights the difficulty to achieve agreement in the histopathological diagnosis of epilepsy surgery brain samples as was already discussed above.

     summary: Although formic acid may not adversely affect histology after short exposure times of one hour, its long-term effects on brain tissue preservation are still a concern (Brown et al., 1990). A more recent study using mass spectrometry found that there was a loss of phosphatidylethanolamine and phosphatidylserine detection in fixed brain tissue, while sphingolipids remained intact after years of storage in formalin (Gaudin et al., 2014).

     summary: Our investigation highlights the superior efficacy of sarkosyl, an anionic surfactant traditionally used to prepare protein lysates from brains and cultured neurons, in preserving the aggregated state of tau dGAE fibrils in vitro, underscoring its potential for further exploratory studies. Although sarkosyl has traditionally been used to prepare lysates from brain tissues and from cultured neurons to detect tau aggregates, the effectiveness of sarkosyl in maintaining the aggregated state of tau dGAE fibrils in vitro presents a promising avenue for future studies.

     summary: Regarding the understanding of brain tumor development and progression, several novel mechanisms have been presented which might also be considered as treatment targets in the future, such as a) autonomous rhythmical Ca2+ oscillations in interconnected glioma cell networks driving tumor growth; b) transfer of mitochondria from normal astrocytes to glioma cells enhancing proliferation and self-renewal; c) brain endothelial cell remodeling upon matrix-metalloprotease 9 secretion by tumor cells metastasizing into the CNS and d) anti-tumor activity of microglia in CNS metastasis of breast cancer. Once cancer cells successfully extravasated and started perivascular metastatic growth, prominent endothelial cell remodeling led to the formation of capillary loops that followed the localization of tumor cells.

Goodwill Published: 07 October 2024 https://doi.org/10.17879/freeneuropathology-2024-5817 Keywords: Pigmented, Ependymoma, YAP1, Siderosis, DNA methylation Ependymomas containing pigmented tumor cells are rare, with only 17 reported cases in the literature1,2,3,4, most of which arrising from the fourth ventricle or adjacent locations in the infratentorial compartment. Furthermore, the presence of lipofuscin argues in favor of postmitotic tumor cells that have aged long enough to allow for the accumulation of non-degradable proteins within the cytoplasm.

     summary: The reviews on brain tissue cryopreservation have tended to focus on aspects other than histology, such as biobanking in general (Shabihkhani et al., 2014) or cellular survival (Paynter, 2008). Second, our review focused primarily on brain tissue cryopreservation, with limited consideration of other tissue types.

The question arises if these tumors should be included in the G3/MMR high-risk subgroup where MMR mutations are causative, or if their tumors, like the M53/SC case, show only added hypermutator phenotype to a baseline mutation core that fits another G1–G7 subgroup and show therefore better prognosis.

In contrast to previously reported CNS cases harboring an alternative gene fusion of the PRC1.1 complex, the current tumor presented histopathological similarities to CNS tumors with BCOR alterations but not sarcomas (5).

An important next step in the development of time-dependent transcriptomics would be expanding its applicability to cells that remain within a distinct cellular collec- tive, such as brain tumor cells.

     summary: The new diagnostic framework of MS establishes MS as a disease continuum and allows diagnosis based on purely biologic considerations in the absence of any clinical manifestation and new imaging and biomarkers as well as AI approaches may facilitate the prediction of the disease course and treatment responses in individual pwMS in the not too far future. New studies reinforce the strong link between Epstein-Barr virus (EBV) and MS, while recent data point towards a role of genetics in MS disease progression.

      flesch: 43
     summary: Introduction Since the 1950s, when the synapse was first visualized with an electron microscope, the ultra- structural analysis of brain tissue has enabled many critical discoveries about the structure of the brain (Sotelo, 2020; Nahirney and Tremblay, 2021). Previous studies have found that fixation and sample preparation methods can influence the visualized ultrastructure of brain tissue (Schiff and Gennaro Jr., 1979; Small, 1981; Sele et al., 2019; Eberhardt et al., 2022; Shafiei et al., 2024).

     summary: Results Approach to brain perfusion In preliminary experiments, we cannulated and perfused the common carotid arteries using an anterior cervical approach that has previously been demonstrated to provide high-quality perfusion of the brain (Insausti et al., 2023). The complex interplay between these factors – agonal state, age, disease history, medications, and environmental circumstances during the PMI – likely contributes to substantial variability in postmortem brain perfusion beyond the PMI alone.
