Transplantation of bone marrow mesenchymal stem cells improves cognitive deficits and alleviates neuropathology in animal models of Alzheimer ’s disease: a meta-analytic review on potential mechanisms

ConclusionsMultiple signal pathways involve therapeutic mechanisms by which the transplantation of BMMSCs improves cognitive and behavioral deficits in AD models. Gene expression profile can be utilized to establish statistical regression model for the evaluation of therapeutic effect. The transplantation of autologous BMMSCs maybe a prospective therapy for patients with Alzheimer ’s disease.

AbstractVascular dementia (VD) is the second most common cause of dementia following Alzheimer ’s disease (AD). The major symptoms of VD including memory loss, language deficits and impairment of executive functions. Its specific etiology and pathogenesis remain unknown. Currently, treatment options of VD are still limited. The therapeutic strategies aim to control the vascular risk factors and improve the cognitive function. In recent years, cell therapy for neurodegenerative diseases has attracted a great deal of attention. Evidence suggested that stem cell transplantation could improve the symptoms of cerebral inf...

Age-Related Epigenetic Changes that Suppress Mitochondrial Function https://www.fightaging.org/archives/2020/03/age-related-epigenetic-changes-that-suppress-mitochondrial-function/ Today's open access research reports on two specific epigenetic changes observed in old individuals that act to reduce mitochondrial function. This joins an existing list of genes for which expression changes are known to impact mitochondrial function with age. A herd of hundreds of mitochondria are found ...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

Publication date: Available online 2 July 2019Source: Biochimica et Biophysica Acta (BBA) - Molecular Basis of DiseaseAuthor(s): Arubala P. Reddy, Janani Ravichandran, Nurgul Carcaci-SalliAbstractNeurodegenerative diseases are devastating mental illnesses without a cure. Alzheimer's disease (AD) characterized by memory loss, multiple cognitive impairments, and changes in personality and behavior. Although tremendous progress has made in understanding the basic biology in disease processes in AD and PD, we still do not have early detectable biomarkers for these diseases. Just in the United States alone, federal and nonfeder...

In this study, we aimed to decipher the role of neurotrophic factors in the reversal of memory loss by transplantation of lineage negative (Lin-ve) stem cells in a male mouse model of cognitive impairment induced by intrahippocampal injection of amyloid β-42 (Aβ-42). The efficacy of human umbilical cord blood (hUCB) derived Lin-ve stem cells were analyzed by neurobehavioral parameters, i.e., Morris water maze and passive avoidance after bilateral intra-hippocampal transplantation using stereotaxic surgery. Real-time PCR and immunohistochemistry w as carried out in brain tissues in order to analyze the expression ...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...
