Potential Alzheimer's disease therapeutic target identified in brain immune cells
- Details
- Category: Research
Tim-3 is an immune checkpoint molecule involved in immunity and inflammation recently linked to late-onset Alzheimer's disease (AD), but its role in the brain was unknown until now. In a paper published in Nature, researchers from Mass General Brigham used preclinical models to uncover Tim-3's role in microglia, the brain's resident immune cells, and have identified it as a promising therapeutic target for Alzheimer's disease.
New study reveals how tumors hijack key nutrient to evade immune attack
- Details
- Category: Research
Chinese scientists have revealed a hidden metabolic partnership between breast cancer cells and immune cells that drives aggressive tumor behavior and resistance to immunotherapies. The study sheds light on how tumor cells exploit the amino acid arginine to both fuel their growth and evade the immune system.
The research was led by Prof. HU Hai, who holds dual appointments as professor at the Hangzhou Institute of Medicine (HIM) of the Chinese Academy of Sciences (CAS), and Chief Physician at Zhejiang Cancer Hospital, in collaboration with Prof. LUO Manli from Sun Yat-Sen University and Prof. LI Hongde from HIM.
Alternative approach to Lyme disease vaccine development shows promise in pre-clinical models
- Details
- Category: Research
Meeting the unmet need for a vaccine is the top priority for researchers studying Lyme disease, which infects about 476,000 people in the U.S. each year and can come with severe complications such as ongoing fatigue and joint issues. Vaccine developers have come close to success, but no human vaccine has yet been commercially viable.
After decades of trial and error, a promising new target is emerging - the Lyme bacterial protein CspZ, which the bacteria use to evade detection from the body's immune system.
Researchers find key to treating painful dry mouth disorder

- Category: Research
A significant discovery has identified a missing "gatekeeper" protein as the root cause of dry mouth in Sjögren's syndrome - a finding that could change the way the disease is treated. Researchers pinpointed tricellulin, a protein that helps seal the junctions between saliva gland cells, as the key factor. When inflammation damages tricellulin, saliva production stops and harmful substances leak through.
New research paves the way for better treatment of strokes

Every year, millions of people around the world suffer ischemic strokes that block blood flow to a region of the brain.
Restoring blood flow rapidly is decisive and can save lives. But paradoxically, it can also lead to further damage to the blood vessels in the brain.
New study helps optimize gene therapy
- Details
- Category: Research
Gene therapy, a technique that is revolutionizing the treatment of multiple genetic conditions, including eye and muscle diseases and blood disorders, requires efficient and specific delivery of the genetic material to the tissue and cell type of interest. To help improve gene therapy, a multidisciplinary team led by researchers at Baylor College of Medicine, the Jackson Laboratory and the University of Massachusetts Medical School has generated a comprehensive atlas that researchers can use to select the most effective viral vehicle for their target organ.
New research finds novel drug target for acute myeloid leukemia
- Details
- Category: Research
A team of scientists from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) has identified a promising new drug target for acute myeloid leukemia (AML), a deadly blood cancer with a five-year survival rate of just 30%, according to the National Cancer Institute. Their study, published in Cell Stem Cell in February, highlights the crucial role of a protein called paraspeckle component 1 (PSPC1) in the progression of AML.
