This superfood, also known as "Lion's Mane", can improve brain ailments, including Alzheimer's
A recent study sheds light on this mushroom's therapeutic potential, revealing that its polysaccharide-enriched extract may significantly alleviate symptoms of AD and protect nerve cells from apoptosis through mitochondrial pathways.
Alzheimer's and its urgent need for alternatives
Researchers are continuously finding ways to explore alternatives to counter this deadly brain-altering disease. AD, accounting for over 60% of dementia cases worldwide, is marked by progressive cognitive decline and poor prognosis.
If left untreated, it can lead to fatal complications like pulmonary embolism and even infections.
The study titled
'The Neuroprotective Properties of Hericium erinaceus in Glutamate-Damaged Differentiated PC12 Cells and an Alzheimer's Disease Mouse Model'
shows that one of the key pathological features of AD includes neuronal apoptosis, heavily associated with mitochondrial dysfunction, particularly an overload of intracellular calcium and the production of reactive oxygen species (ROS), leading to cellular death.Animal and cellular models have become crucial in testing potential interventions.

In this study, researchers used PC12 cells—a type of rat pheochromocytoma cell line known for mimicking neuronal behavior—as well as a mouse model induced with Alzheimer's-like symptoms through d-galactose and aluminum chloride (AlCl₃) administration.
Lion's mane: Mushroom with medicinal might
Hericium Erinaceus is no stranger to the world of traditional medicine, often used for its antitumor and antioxidant effects. However, its neuroprotective capabilities are increasingly catching scientists' interest.
This miracle mushroom is known to stimulate nerve growth factor (NGF) and support cholinergic neuron development.
Other benefits of Lion's mane
It supports mental health by alleviating symptoms of anxiety and depression
It helps to improve sleep and also reduces irritability
It fights oxidative stress and protects cells from aging
It protects against gastric ulcers and stomach inflammation
Key findings
In l-glutamate-induced PC12 cell models, HE showed a marked ability to reverse nuclear apoptotic changes. At concentrations of 50 and 100 µg/mL over 24 and 48 hours, HE stimulated the transformation of PC12 cells into neuron-like shapes, similar to the effect of NGF. The treated cells developed axons and polygonal morphology, with an increase in β-tubulin III expression—a key marker of neuronal differentiation.
Notably, HE improved cell viability by mitigating mitochondrial damage and reestablishing membrane potential, thereby preventing apoptosis triggered by oxidative stress and calcium overload.
The outcomes of this research underscore HE's potential to interfere with denigrative processes underlying Alzheimer's, notably by targeting the mitochondrial-mediated apoptotic pathway.
Our scientists have progressed so much that they are now turning to nature's most overlooked resources, such as fungi, for answers to some of the most complex diseases in nature, like Alzheimer's.

7 women pregnant after free IVF treatment at GMC
Panaji: Seven women who received free IVF treatment at GMC's Centre for Assisted Reproductive Treatment (ART) are currently pregnant. The centre operates under an MoU signed between the public health dept, GMC, and Dr Kedar's Maternity, Infertility, and Surgical Hospital (Subunit: Goa IVF Centre) in Panaji. Nine women who underwent the IVF treatment at the GMC's super specialty block have successfully delivered to date. The centre has 316 persons registered for ART and has performed 104 IVF procedures on 69 patients to date. The centre has also performed 403 IUI procedures on 172 patients. The cost per IVF case is around Rs 1.37 lakh, health minister Vishwajit Rane said in a written reply in the assembly. This includes Rs 1 lakh for injections for ovarian hyperstimulation, Rs 8,000 for medicines after OPU and embryo transfer, Rs 7,000 for IVF media and Rs 12,000 for IVF consumables. As per the MoU between the GMC's public health department and Dr Kedar's Maternity, Infertility, and Surgical Hospital, Panaji, Goa, Dr Kedarnath Padte and his team of anaesthetists, embryologists and support staff provide their services at the Centre for ART, SSB, GMC. In May, the centre reported the birth of triplets to a mother, the first of its kind at the facility.

KGMU intensifies preps for NAAC evaluation
Lucknow: KGMU is going all out on its mission to secure a higher grade in the upcoming assessment by the National Assessment and Accreditation Council (NAAC). The NAAC peer team is scheduled to visit the university for a three-day inspection from July 31 to Aug 2. Having received an 'A+' grade in 2023, the university reapplied with the objective of improving its overall score and getting A++ (the top grade). According to the officials, vice chancellor Prof Soniya Nityanand is supervising the preparations, with all clinical and non-clinical departments aligning their work with the assessment framework. Mock presentations are being conducted across departments to highlight various aspects of institutional functioning. NAAC assesses higher education institutions on seven key criteria: teaching-learning and evaluation; research, innovations, and extension; infrastructure and learning resources; student support and progression; governance, leadership and management; and institutional values and best practices. In its previous assessment, KGMU received lower scores in areas related to student activities and placement outcomes. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Doctor: '10-Second Morning Method Helps Drain Swollen Legs" (See How) goldentree Learn More Undo The university also faced difficulties in presenting its research data comprehensively. Steps have since been taken to address these gaps. KGMU comprises 149 buildings, 77 departments and over 4,000 hospital beds. It has a workforce of more than 550 faculty members, 800 resident doctors and approximately 10,000 other staff members. To support its operations and academic initiatives, the Uttar Pradesh govt allocated Rs 1,843.7 crore to the university in this year's budget. "Ahead of the NAAC visit, the university has worked to compile its research documentation and improve student-related activities. Efforts are focused on presenting these developments clearly during the assessment," said a senior official.

China PM warns against a global AI 'monopoly'
China PM warns against a global AI 'monopoly' China will spearhead the creation of an international organisation to jointly develop AI, the country's premier said, seeking to ensure that the world-changing technology doesn't become the province of just a few nations or companies. Artificial intelligence harbours risks from widespread job losses to economic upheaval that require nations to work together to address, Premier Li Qiang told the World Artificial Intelligence Conference in Shanghai on Saturday. That means more international exchanges, Beijing's No 2 official said during China's most important annual technology summit. Li didn't name any countries in his short address to kick off the event. But Chinese executives and officials have taken aim at Washington's efforts to curtail the Asian country's tech sector, including by slapping restrictions on the export of Nvidia chips crucial to AI development. On Saturday, Li acknowledged a shortage of semiconductors was a major bottleneck, but reaffirmed President Xi Jinping's call to establish policies to propel Beijing's ambitions. The govt will now help create a body - loosely translated as the World AI Cooperation Organization - through which countries can share insights and talent. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The Most Beautiful Female Athletes Right Now Undo "Currently, key resources and capabilities are concentrated in a few countries and a few enterprises. If we engage in technological monopoly, controls and restrictions, AI will become an exclusive game for a small number of countries and enterprises," Li told hundreds of delegates huddled at the conference venue on the banks of Shanghai's iconic Huangpu river. China and the US are locked in a race to develop a technology with the potential to turbocharge economies and - over the long run - tip the balance of geopolitical power. This week, US President Donald Trump signed executive orders to loosen regulations and expand energy supplies for data centers - a call to arms to ensure companies like OpenAI and Google help safeguard America's lead in the post-ChatGPT era. At the same time, the breakout success of DeepSeek has inspired Chinese tech leaders and startups to accelerate research and roll out AI products. The weekend conference in Shanghai - gathering star founders, Beijing officials and deep-pocketed financiers by the thousands - is designed to catalyze that movement. The event, which has featured Elon Musk and Jack Ma in years past, was launched in 2018. This year's attendance may hit a record because it's taking place at a critical juncture in the global race to lead GenAI development. It's already drawn some notable figures: Nobel Prize laureate Geoffrey Hinton and former Google chief Eric Schmidt were among heavyweights who met Shanghai party boss Chen Jining Thursday, before they were due to speak at the event.
