Role of Amyloid Precursor Protein (APP) and Its Derivatives in the Biology and Cell Fate Specification of Neural Stem Cells
Amyloid precursor protein (APP) is a member of the APP family of proteins, and different enzymatic processing leads to the production of several derivatives that are shown to have distinct biological functions. APP is involved in the pathology of Alzheimer's disease (AD), the most common neurodegen...
Micromotor-based electrochemical immunoassays for reliable determination of amyloid-β (1-42) in Alzheimer's diagnosed clinical samples
Alzheimer's disease (AD), in addition to being the most common cause of dementia, is very difficult to diagnose, with the 42-amino acid form of Aβ (Aβ-42) being one of the main biomarkers used for this purpose. Despite the enormous efforts made in recent years, the technologies available to determi...
Electroanalytical Immunotool to Determine Matricellular Protein Periostin, a Stromal Biomarker of Prognosis in Colorectal Cancer
Tumor-associated stroma biomarkers are emerging as key signaling molecules of metastasis in colorectal cancer (CRC). In this sense, periostin (POSTN), a protein of the extracellular matrix from the stromal compartment, is envisioned as a potential stromal prognostic biomarker, which facilitates the...
Bronchoalveolar cytokine profile differentiates Pulmonary Langerhans cell histiocytosis patients from other smoking-related interstitial lung diseases
Background: Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial lung disease (ILD) associated with smoking, whose definitive diagnosis requires the exclusion of other forms of ILD and a compatible surgical lung biopsy. Bronchoalveolar lavage (BAL) is commonly proposed for the diag...
Hepatitis E Virus Seroprevalence is Associated with Neurodegenerative Disorders in Older People with Dementia: A Case-Control Study
In this case-control study, we evaluated the association between serum antibodies against hepatitis E virus (HEV) and central nervous system (CNS) neurodegenerative disorders (NDs) in older people with dementia. The presence of anti-HEV antibodies was related to a higher adjusted odds ratio (aOR) o...
Aβ42 Peptide Promotes Proliferation and Gliogenesis in Human Neural Stem Cells
Amyloid-β 42 [Aβ1-42 (Aβ42)] is one of the main Aβ peptide isoforms found in amyloid plaques of brains with Alzheimer's disease (AD). Although Aβ42 is associated with neurotoxicity, it might mediate several normal physiological processes during embryonic brain development and in the adult brain. Ho...
Advances in Alzheimer’s Disease Research: Human Cerebral Organoids
Alzheimer’s disease (AD) is the main neurodegenerative disorder in old age, causing memory impairment and dependency. The histopathology of AD is characterized by the presence of amyloid plaques and neurofibrillary tangles formed by Aβ peptide and hyperphosphorylated Tau, respectively. There is sti...
Highly efficient generation of human Cerebral Organoids bypassing embryoid body stage
Human cerebral organoids (hCOs) are a promising in vitro model that may overcome some of the limitations that currently exist when studying human brain development and disease. Since Lancaster et al. first generated hCOs, efforts have been made to better recapitulate the physiology of the human bra...
Effects of Polystyrene Nanoplastics on the biology of human Neural Stem Cells and human Cerebral Organoids
Global plastic production has increased exponentially in recent decades and a significant proportion persists in the environment, where it is degraded by mechanical and physical processes giving rise to micro (< 5mm) and nanoplastics (< 1000 nm; NP) and can reach humans through ingestion, inhalatio...
Neurodevelopmental effects of Cypermethrin in human Neural Stem Cells
The lack of adequate models for the study of developmental neurotoxicity has made difficult to correctly assess the risk and effects of toxic exposure. Despite the large body of results on animals, these studies are costly, time consuming and the results are not always reliable to assess the impact...
RNA-SEQ analysis reveals the implication of Amyloid Precursor Protein (APP) in cell fate specification of human neural Stem Cells by several Signaling Pathways. IBRO Neuroscience Reports
Numerous studies have focused on the pathophysiological role of amyloid precursor protein (APP) in Alzheimer's disease (AD), being the aggregation of β-amyloid (Aβ) peptide a central event. However, many authors consider that alterations in physiological functions of APP are likely to play a key ro...
SINGLE-CELL sequencing workflow to study cellular composition and cell type specific expression profiles of human Cerebral Organoids
Human cerebral organoid culture is a technology with immense potential in the areas of developmental neurobiology and neurodegeneration for example to study cell types, mechanisms involved, to discover of new biomarkers, to propose specific therapeutic strategies or to study the effects of compound...
Studying the cellular and molecular evolution of familiar Alzheimer'sdisease using human Cerebral Organoids
The leading cause of dementia in the elderly is Alzheimer's disease (AD), and its increase is expected in the coming years. The histopathological hallmarks of AD are associated with the presence in brain of neurofibrillary tangles, due to the increase in hyperphosphorylated Tau protein, as well as ...
Early and differential autoimmune diseases diagnosis by interrogating specific autoantibody signatures with multiplexed electrochemical bioplatforms
This work reports the first bioplatform to assist in the early and reliable diagnosis of autoimmune diseases by quadruple determination of autoantibodies (Abs) produced against extractable nuclear antigens (ENAs): La/SSB-Abs, Ro/SSA-Abs, U1snRNP70-Abs and smRNP-Abs. The bioplatform involves indirec...
Dual detection system for cancer-associated point mutations assisted by a multiplexed LNA-based amperometric bioplatform coupled with rolling circle amplification
DNA point mutation in a BRAF proto-oncogene, V600E, is considered an important prognostic and predictive biomarker in various types of cancer, such as melanoma or colorectal cancer. We report here a novel electrochemical (EC) bioplatform for the analysis of BRAF V600E mutation coupled with rolling ...
Benefits of FAIMS to Improve the Proteome Coverage of Deteriorated and/or Cross-Linked TMT 10-Plex FFPE Tissue and Plasma-Derived Exosomes Samples
The proteome characterization of complex, deteriorated, or cross-linked protein mixtures as paired clinical FFPE or exosome samples isolated from low plasma volumes (250 µL) might be a challenge. In this work, we aimed at investigating the benefits of FAIMS technology coupled to the Orbitrap Explor...
Modeling of Respiratory Diseases Evolving with Fibrosis from Organoids Derived from Human Pluripotent Stem Cells
Respiratory disease is one of the leading causes of morbidity and mortality worldwide. There is no cure for most diseases, which are treated symptomatically. Hence, new strategies are required to deepen the understanding of the disease and development of therapeutic strategies. The advent of stem c...
Altered Clock Gene Expression in Female APP/PS1 Mice and Aquaporin-Dependent Amyloid Accumulation in the Retina
Alzheimer's disease (AD), the most prevalent form of dementia, is a neurodegenerative disorder characterized by different pathological symptomatology, including disrupted circadian rhythm. The regulation of circadian rhythm depends on the light information that is projected from the retina to the s...
Schnurri-3 drives tumor growth and invasion in cancer cells expressing interleukin-13 receptor alpha 2
Interleukin 13 receptor alpha 2 (IL13Rα2) is a relevant therapeutic target in glioblastoma (GBM) and other tumors associated with tumor growth and invasion. In a previous study, we demonstrated that protein tyrosine phosphatase 1B (PTP1B) is a key mediator of the IL-13/IL13Rα2 signaling pathway. PT...
