Scientists 3D Print Living, Viable Brain Tumor, to Practice Killing It

Posted by in categories: 3D printing, biotech/medical, neuroscience

A team of mad scientists successfully 3D-printed out a living, “viable” glioblastoma tumor — the deadliest kind of brain cancer — for the express purpose of learning how to kill it.

Practice makes perfect!

Histamine and Inflammation Could Be Key Players in Depression

Posted by in category: neuroscience

What is causing chronic inflammation?

Summary: A new study adds to the growing body of research linking inflammation to depression. Researchers found the molecule histamine directly inhibits the release of serotonin in the brain by attaching to inhibitory receptors on serotonin neurons in mice.

Widespread Pain Linked to Heightened Dementia and Stroke Risk

Posted by in categories: biotech/medical, neuroscience

Widespread pain, a subset of chronic pain associated with musculoskeletal disorders, is linked to an increased risk of all types of dementias, including Alzheimer’s disease, and a greater risk of stroke.

Loss of placental hormone linked to brain and social behavior changes

Posted by in categories: biotech/medical, neuroscience

In the study, researchers in the laboratory of Anna Penn, MD, Ph.D., now at Columbia University Vagelos College of Physicians and Surgeons and previously at Children’s National Hospital in Washington, D.C., found that reducing amounts of a single hormone, called allopregnanolone (ALLO), in the placenta caused brain and behavior changes in male offspring that resemble changes seen in some people with autism spectrum disorder. The study also found that both brain structure and behavioral changes in the mice could be prevented with a single injection of ALLO in late pregnancy.

Preterm birth has been shown to increase the risk of autism spectrum disorders and other developmental problems, particularly in males. The more premature a baby is, the greater the risk of either motor or cognitive deficits. What does the preterm baby lose that is so critical to long-term outcomes?

A new study, in mice, suggests that one factor may be the loss of a placental hormone that the developing would normally see in the second half of pregnancy.

Tiny human brain grown in lab has eye-like structures that ‘see’ light

Posted by in category: neuroscience

A big step in the right direction.

Small blobs of human brain grown in a dish have been coaxed into forming rudimentary eyes, which respond to light by sending signals to the rest of the brain tissue.

Brain organoids develop optic cups that respond to light

Posted by in categories: biotech/medical, neuroscience

Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a study published today in the journal Cell Stem Cell.

Brain Gene Expression Patterns Altered by Chronic Opioid Use

Posted by in category: neuroscience

Summary: Opioid use disorder affects genes associated with proinflammatory immune molecule encoding and genes associated with remodeling the extracellular matrix, suggesting the connection between neurons may be altered as a result of opioid use. Additionally, those with OUD have higher levels of microglia in the brain.

The epidemic of opioid abuse affects millions of people worldwide, but researchers know surprisingly little about the molecular changes caused by opioids in the human brain.
