Innovative Technique Enables In Vivo Imaging of Intracellular Protein Aggregates

Tau aggregates have become the main study focus for figuring out the mechanisms underlying neurodegeneration since they are a prevalent form of amyloid protein. Tau fibrils and oligomers, among other forms of tau aggregates, have been linked to a variety of neurodegenerative disorders.

Stem Cell Zoo Uncovers Scaling Laws Governing Species-Specific Development

Pregnancy last around nine months in humans, only 20 days in mice, and up to 17 months in rhinoceroses. Even though many mammalian species go through the same phases of embryo development, the rate of development varies greatly between animals.

Scientists Discover New Embryonic Cell Type that Self-Destructs to Protect the Developing Embryo

Scientists studying gene activity data of the early human embryo have discovered an overlooked type of cell which self-destructs within days of forming, as part of a quality control process to protect the developing foetus.

Review: Role of Alternative Splicing Defects in Major Neurodegenerative Diseases

Alternative splicing, a clever way a cell generates many different variations of messenger RNAs -; single-stranded RNAs involved in protein synthesis -; and proteins from the same stretch of DNA, plays an important role in molecular biology.

Microglial Cells Serve as a Stable Viral Reservoir for Latent HIV

Human immunodeficiency virus-1 (HIV) introduces a copy of its DNA into human immune cells as part of its life cycle. Some of these newly infected immune cells can subsequently enter an inactive, latent state for an extended length of time, which is known as HIV latency.

Understanding How Genes Predispose Humans to Allergies

New research is expanding the scientific understanding of why some people are more allergic than others. Researchers at the University of Pennsylvania’s Perelman School of Medicine discovered how genetic changes that modify a specific protein called ETS1 can affect our body’s response to allergens.

New Mechanism to Maintain Astrocyte-Neuron Communication

Neurons and astrocytes are the two types of cells required by the brain to enjoy the scent of morning coffee and freshly baked cookies or to discern the warning smell of something burning.

New Data Shows Gene Expression at Different Stages of Pregnancy

While the exterior features of a woman can alter throughout pregnancy, scientists are surprisingly ignorant about the interior biological changes that take place.

iPSC-Based Model System Helps Study Lung-Specific Mesenchyme

Lung mesenchymal cells, which are crucial components of the lung’s distinctive structure, also play a significant role in disease and injury recovery, but research into their biology and how they start disorders like pulmonary fibrosis is limited.

Study Links Timing of Childhood Adversity With Epigenetic Patterns in Adolescents

Childhood adversity-;circumstances that threaten to a child's physical or psychological well-being--has long been associated with poorer physical and mental health throughout life, such as greater risks of developing cardiac disease, cancer, or depression.

Achieving 3D Printing Inside 'Mini-Organs' Growing in Hydrogels

Scientists from the NIHR Great Ormond Street Hospital Biomedical Research Centre (a collaboration between GOSH and UCL), London, and University of Padova, Italy, have shown for the first time how 3D printing can be achieved inside 'mini-organs' growing in hydrogels -- controlling their shape, activity, and even forcing tissue to grow into 'molds.'
