Study Reveals Similarities in Protein Structures Between Alzheimer’s Disease and Down Syndrome
A recent study published in Nature Structural and Molecular Biology has utilized advanced cryo-electron microscopy imaging technology to investigate the similarities in protein structures between Alzheimer’s disease and Down syndrome. Lead investigator Ruben Vidal, Ph.D., highlighted the presence of amyloid β (Aβ) and abnormal accumulation of tau protein in individuals with both Down syndrome and Alzheimer’s disease. The study aimed to determine whether differences exist in the protein structures of Aβ and tau filaments between individuals with only Alzheimer’s disease and those with both Down syndrome and Alzheimer’s disease. The research team conducted a comparative analysis of high-resolution images of Aβ and tau filaments in individuals with Down syndrome and Alzheimer’s disease, and those with only Alzheimer’s disease. Vidal emphasized the potential implications of their findings, suggesting that the study may pave the way for improved treatments for both Alzheimer’s disease patients and individuals with Down syndrome. This study sheds light on the common mechanisms at play in individuals with sporadic Alzheimer’s disease and those with both Down syndrome and Alzheimer’s disease.

Researchers Make Strides in Understanding LAG-3 Protein
Researchers at Stanford University and New York University have made significant strides in understanding the properties of the LAG-3 protein, shedding light on its structure and function. This breakthrough could have far-reaching implications for the development of immune checkpoint inhibitor drug candidates targeting LAG-3. The study, published in Proceedings of the National Academy of Sciences, provides crucial insights into the molecular structure of LAG-3 and how it operates. LAG-3, like other checkpoint proteins, serves to prevent the immune system from attacking non-threatening entities. In the context of cancer, these proteins can shield tumor cells from immune recognition, hindering the body’s natural defense mechanisms. While existing antibody treatments focus on checkpoint proteins CTLA-4 and PD-1, the unique mode of action of LAG-3 presents an opportunity for novel approaches in cancer therapy. Scientists are optimistic about the potential of targeting LAG-3, driven by its distinct mechanisms compared to CTLA-4 and PD-1.
