Abstract: Neurodegenerative diseases affect a considerable percentage of the elderly population. New therapeutic approaches are warranted, aiming to at least delay and possibly reverse disease progression. Strategies to elaborate such approaches require knowledge of specific immune system involvement in disease pathogenesis. In this review, innate and adaptive immunological aspects of neurodegenerative disorders, in particular Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis (ALS), are discussed. Initiating disease factors, as well as common mechanistic pathways, are detailed and potential immunological therapeutic targets are identified.

Abstract: Accumulating evidence has demonstrated that menstrual blood stands as a viable source of stem cells. Menstrual blood-derived stem cells (MenSCs) are morphologically and functionally similar to cells directly extracted from the endometrium, and present dual expression of mesenchymal and embryonic cell markers, thus becoming interesting tools for regenerative medicine. Functional reports show higher proliferative and self-renewal capacities than bone marrow-derived stem cells, as well as successful differentiation into hepatocyte-like cells, glial-like cells, endometrial stroma-like cells, among others. Moreover, menstrual blood stem cells may be used with increased efficiency in reprogramming techniques for induced Pluripotent Stem cell (iPS) generation. Experimental studies have shown successful treatment of stroke, colitis, limb ischemia, coronary disease, Duchenne's muscular atrophy and streptozotocin-induced type 1 diabetes animal models with MenSCs. As we envision an off-the-shelf product for cell therapy, cryopreserved MenSCs appear as a feasible clinical product. Clinical applications, although still very limited, have great potential and ongoing studies should be disclosed in the near future.

Abstract: Using EBMT data in patients from 1994 to 2015, we analyzed the development and factors influencing outcomes of HSCT for ADs. Transplant center experience, accreditation, and national socioeconomic factors are relevant for outcomes and future health service delivery.

Abstract: Cell therapy has been established as an important field of research with considerable progress in the last years. At the same time, the progressive aging of the population has highlighted the importance of discovering therapeutic alternatives for diseases of high incidence and disability, such as stroke. Menstrual blood is a recently discovered source of stem cells with potential relevance for the treatment of stroke. Migration to the infarct site, modulation of the inflammatory reaction, secretion of neurotrophic factors, and possible differentiation warrant these cells as therapeutic tools. We here propose the use of autologous menstrual blood cells in the restorative treatment of the subacute phase of stroke. We highlight the availability, proliferative capacity, pluripotency, and angiogenic features of these cells and explore their mechanistic pathways of repair. Practical aspects of clinical application of menstrual blood cells for stroke will be discussed, from cell harvesting and cryopreservation to administration to the patient.

Abstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive motor neuron death, leading to muscle atrophy, paralysis, and death usually within 3 to 5 years after diagnosis. Most cases are sporadic, with still undefined etiopathogenesis. Both the innate and adaptive immune systems are involved in ALS, with special participation of T lymphocytes and microglia. Inflammation plays a dual role in the disease, protective and T regulatory cell rich in the early stages and deleterious as disease progresses. Attempts to modulate immune/inflammatory system response are reported in the literature, and while beneficial effects are achieved in ALS animal models, results of most clinical trials have been disappointing. The impaired blood-brain barrier is an important feature in the pathogenesis of ALS and likely affects the immune system response. The present review describes the role of the immune system in ALS pathogenesis and the tight coupling of immunity and central nervous system barrier function.

Abstract: Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease with a complicated pathogenesis. Compelling evidence indicates impairment of all neurovascular unit components including the blood-brain and blood-spinal cord barriers (BBB/BSCB) in both patients and animal models, leading to classification of ALS as a neurovascular disease. The present review provides an updated analysis of the normal and impaired BBB/BSCB, focusing on the ALS-altered barrier. Here we describe the roles of cellular components, tight junctions, transport systems, cell interactions, cytokines, matrix metalloproteinases, and free radicals in the BBB/BSCB disruption, along with recent evidence from experimental and clinical ALS studies. The BBB/BSCB is a promising research area in ALS and this review will reveal some aspects of microvascular pathology in ALS and hopefully provide ideas for the development of new therapeutic strategies.

Abstract: Cerebrovascular diseases are the third leading cause of death and the primary cause of long-term disability in the United States. The only approved therapy for stroke is tPA, strongly limited by the short therapeutic window and hemorrhagic complications, therefore excluding most patients from its benefits. Parkinson's and Huntington's disease are the other two most studied basal ganglia diseases and, as stroke, have very limited treatment options. Inflammation is a key feature in central nervous system disorders and it plays a dual role, either improving injury in early phases or impairing neural survival at later stages. Stem cells can be opportunely used to modulate inflammation, abrogate cell death and, therefore, preserve neural function. We here discuss the role of stem cells as restorative treatments for basal ganglia disorders, including Parkinson's disease, Huntington's disease and stroke, with special emphasis to the recently investigated menstrual blood stem cells. We highlight the availability, proliferative capacity, pluripotentiality and angiogenic features of these cells and explore their present and future experimental and clinical applications.

Abstract: Vascular pathology, including blood-brain/spinal cord barrier (BBB/BSCB) alterations, has recently been recognized as a key factor possibly aggravating motor neuron damage, identifying a neurovascular disease signature for ALS. However, BBB/BSCB competence in sporadic ALS (SALS) is still undetermined. In this study, BBB/BSCB integrity in postmortem gray and white matter of medulla and spinal cord tissue from SALS patients and controls was investigated. Major findings include (1) endothelial cell damage and pericyte degeneration, (2) severe intra- and extracellular edema, (3) reduced CD31 and CD105 expressions in endothelium, (4) significant accumulation of perivascular collagen IV, and fibrin deposits (5) significantly increased microvascular density in lumbar spinal cord, (6) IgG microvascular leakage, (7) reduced tight junction and adhesion protein expressions. Microvascular barrier abnormalities determined in gray and white matter of the medulla, cervical, and lumbar spinal cord of SALS patients are novel findings. Pervasive barrier damage discovered in ALS may have implications for disease pathogenesis and progression, as well as for uncovering novel therapeutic targets.

Abstract: Cerebrovascular diseases are a major cause of death and long-term disability in developed countries. Tissue plasmin activator (tPA) is the only approved therapy for ischemic stroke, strongly limited by the short therapeutic window and hemorrhagic complications, therefore excluding most patients from its benefits. The rescue of the penumbra area of the ischemic infarct is decisive for functional recovery after stroke. Inflammation is a key feature in the penumbra area and it plays a dual role, improving injury in early phases but impairing neural survival at later stages. Stem cells can be opportunely used to modulate inflammation, abrogate cell death and, therefore, preserve neural function. We here discuss the possible role of stem cells derived from menstrual blood as restorative treatment for stroke. We highlight the availability, proliferative capacity, pluripotentiality and angiogenic features of these cells and explore their present and future experimental and clinical applications.
