    Researchers have discovered the vital role of a hormone, that develops in men during puberty, in providing an early prediction of whether they could develop certain diseases in later life.

    Scientists from the University of Nottingham have discovered that the novel insulin-like peptide hormone, called INSL3, is consistent over long periods of time and is an important early biomarker for prediction of age-linked disease. Their latest findings have been published today in Frontiers in Endocrinology.

    INSL3 is made by the same cells in the testes that make testosterone, but unlike testosterone which fluctuates throughout a man’s life, INSL3 remains consistent, with the level at puberty remaining largely the same throughout a man’s life, decreasing only slightly into old age...

    Study shows that Adaptive Immune Responses can cause Cellular Loss in the Aging-Related Brain

    Study shows that adaptive immune responses can cause cellular loss in the aging brain
    The cell type composition of scRNA-seq was analyzed and oligodendrocytes were separated into four different sub-clusters. Two previously unknown oligodendrocyte clusters appeared in aged mice, which were enriched in the white matter. One was associated with injury responses. Because this cluster was highly enriched in the aged white matter, it was named aging-related oligodendrocytes (Fig. 1b-c, e). Also a smaller interferon-responsive oligodendrocyte subpopulation (IRO) was characterized by the expression of genes commonly associated with an interferon response. Credit: Kaya et al.

    Past neuroscience studies have consistently demonstrated that the aging of the mammalian nervous system is liked with a decline in the volume and functioning of white matter, nerve fibers found in deep brai...

    Brain Changes in Autism are far more sweeping than previously known, study finds

    November 4, 2022, Categories  Health/Medical, Biology/Biotechnology

    This shows a brain
    The new study finds brain-wide changes in virtually all of the 11 cortical regions analyzed, regardless of whether they are higher critical association regions – those involved in functions such as reasoning, language, social cognition and mental flexibility – or primary sensory regions. Image is in the public domain

    Brain changes in autism are comprehensive throughout the cerebral cortex rather than just particular areas thought to affect social behavior and language, according to a new UCLA-led study that significantly refines scientists’ understanding of how autism spectrum disorder (ASD) progresses at the molecular level.

    The study, published today in Nature, represents a comprehensive effort to characterize ASD at the molecular level...
