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.

The gut microbiota plays an important role in human health and the prevention of disease. As a result, changes in its regular functioning may play a part in some medical conditions, such as irritable bowel syndromeTrusted Source, obesityTrusted Source, and cardiovascular diseasesTrusted Source.

A recent study investigates the connection between high fat diets, gut bacteria, and an increased risk of developing heart disease.

New evidence shows that patients with Long COVID syndrome continue to have higher measures of blood clotting, which may help explain their persistent symptoms, such as reduced physical fitness and fatigue.

The study, led by researchers from RCSI University of Medicine and Health Sciences, is published in the Journal of Thrombosis and Haemostasis.

Previous work by the same group studied the dangerous clotting observed in patients with severe acute COVID-19. However, far less is known about Long COVID syndrome, where symptoms can last weeks to months after the initial infection has resolved and is estimated to affect millions of people worldwide.

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.

An artificial neural network (AI) designed by an international team involving UCL can translate raw data from brain activity, paving the way for new discoveries and a closer integration between technology and the brain.

The new method could accelerate discoveries of how brain activities relate to behaviors.

The study published today in eLife, co-led by the Kavli Institute for Systems Neuroscience in Trondheim and the Max Planck Institute for Human Cognitive and Brain Sciences Leipzig and funded by Wellcome and the European Research Council, shows that a convolutional neural network, a specific type of deep learning algorithm, is able to decode many different behaviors and stimuli from a wide variety of brain regions in different species, including humans.

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 brain would normally see in the second half of pregnancy.

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.

What if we are living in a simulation, and the world as we know it is not real? To tackle this mind-bending idea, acclaimed filmmaker Rodney Ascher (ROOM 237 THE NIGHTMARE) uses a noted speech from Philip K. Dick to dive down the rabbit hole of science, philosophy, and conspiracy theory. Leaving no stone unturned in exploring the unprovable, the film uses contemporary cultural touchstones like THE MATRIX, interviews with real people shrouded in digital avatars, and a wide array of voices, expert and amateur alike. If simulation theory is not science fiction but fact, and life is a video game being played by some unknowable entity, then who are we, really? A GLITCH IN THE MATRIX attempts to find out.
