    Culinary and medicinal mushrooms have been appreciated since prehistoric times as valuable resources for food and medicine. Edible mushrooms represent an untapped source of nutraceuticals and valuable palatable food. Long considered tonics, they are now treasured as functional foods that can improve human health and quality of life. Numerous studies have provided insights into the neuroprotective effects of edible mushrooms, which are attributed to their antioxidant, antineuroinflammatory, and cholinesterase inhibitory properties, and their ability to prevent neuronal death. Here we review the recent literature on the role of culinary and medicinal mushrooms in the management of neurodegenerative diseases and neurotrauma. We highlight some of the molecular mechanisms for how these alternative medicines provide health benefits that could help us to harness their neuroprotective effects.

    Stem cells can multiply into more cells with similar types in an undifferentiated form and differentiate into other types of cells. The great success and key essence of stem cell technology is the isolation of high-quality Mesenchymal Stem Cells (MSCs) with high potency, either with multipotent or pluripotent property. In this line, Stem cells from Human Exfoliated Deciduous teeth (SHEDs) are highly proliferative stem cells from dental pulp and have multipoint differentiation capacity. These cells play a pivotal role in regenerative medicine, such as cell repair associated with neurodegenerative, hepatobiliary, and pancreatic diseases. In addition, stem cell therapy has been widely used to regulate immune response and repair of tissue lesions. This overview captured the differential biological characteristics, and the potential role of stem cell technology and paid special attention to human welfare SHEDs in eliminating the above-mentioned diseases. This review provides further insights into stem cell technology by expanding the therapeutic potential of SHEDs in tissue engineering and cell organ repairs.

    Excessive exposure to toxic substances or chemicals in the environment and various pathogens, including viruses and bacteria, is associated with the onset of numerous brain abnormalities. Among them, pathogens, specifically viruses, elicit persistent inflammation that plays a major role in Alzheimer's disease (AD) as well as dementia. AD is the most common brain disorder that affects thought, speech, memory and ability to execute daily routines. It is also manifested by progressive synaptic impairment and neurodegeneration, which eventually leads to dementia following the accumulation of Aβ and hyperphosphorylated Tau. Numerous factors contribute to the pathogenesis of AD, including neuroinflammation associated with pathogens, and specifically viruses. The human immunodeficiency virus (HIV) is often linked with HIV-associated neurocognitive disorders (HAND) following permeation through the blood-brain barrier (BBB) and induction of persistent neuroinflammation. Further, HIV infections also exhibited the ability to modulate numerous AD-associated factors such as BBB regulators, members of stress-related pathways as well as the amyloid and Tau pathways that lead to the formation of amyloid plaques or neurofibrillary tangles accumulation. Studies regarding the role of HIV in HAND and AD are still in infancy, and potential link or mechanism between both is not yet established. Thus, in the present article, we attempt to discuss various molecular mechanisms that contribute to the basic understanding of the role of HIV-associated neuroinflammation in AD and HAND. Further, using numerous growth factors and drugs, we also present possible therapeutic strategies to curb the neuroinflammatory changes and its associated sequels.

    INTRODUCTION: Mesenchymal Stem Cell (MSC) therapy in recent years has gained significant attention. Though the functional outcomes following MSC therapy for neurodegenerative diseases are convincing, various mechanisms for the functional recovery are being debated. Nevertheless, recent studies convincingly demonstrated that recovery following MSC therapy could be reiterated with MSC secretome per se thereby shifting the dogma from cell therapy to cell "based" therapy. In addition to various functional proteins, stem cell secretome also includes extracellular membrane vesicles like exosomes. Exosomes which are of "Nano" size have attracted significant interest as they can pass through the bloodbrain barrier far easily than macro size cells or growth factors. Exosomes act as a cargo between cells to bring about significant alterations in target cells. As the importance of exosomes is getting unveil, it is imperial to carry out a comprehensive study to evaluate the neuroprotective potential of exosomes as compared to conventional co-culture or total condition medium treatments.

    OBJECTIVE: Thus, the present study is designed to compare the neuroprotective potential of MSC derived exosomes with MSC-condition medium or neuron-MSC-co-culture system against kainic acid induced excitotoxicity in in vitro condition. The study also aims at comparing the neuroprotective efficacy of exosomes/condition medium/co-culture of two MSC viz., neural crest derived human Dental Pulp Stem Cells (hDPSC) and human Bone-Marrow Mesenchymal Stem Cells (hBM-MSC) to identify the appropriate MSC source for treating neurodegenerative diseases.

    RESULT: Our results demonstrated that neuroprotective efficacy of MSC-exosomes is as efficient as MSC-condition medium or neuron-MSC co-culture system and treating degenerating hippocampal neurons with all three MSC based approaches could up-regulate host's endogenous growth factor expressions and prevent apoptosis by activating cell survival PI3K-B-cell lymphoma-2 (Bcl-2) pathway.

    CONCLUSION: Thus, the current study highlights the possibilities of treating neurodegenerative diseases with "Nano" size exosomes as opposed to transplanting billions of stem cells which inherit several disadvantages.
