The Immune System

A new study has uncovered a previously unknown link between the immune system and the fear response, and how psychedelics can play a role in suppressing it. The finding could improve the treatment of both mental, emotional and physical afflictions.

In a breakthrough finding, researchers have discovered that immune cells near the spinal cord are triggered by estrogen and progesterone to produce a natural painkiller called enkephalin. The finding could change the way we treat chronic pain.

Egg prices have slowly come down, thanks to supply and demand issues leveling out and a reprieve in bird flu outbreaks. But the truth is that the cost is unlikely to stay low. Here's a handy guide to getting all the protein you need – on any budget.

Recent human trials of a new one-year-long immune-based treatment for post-polio syndrome, which can strike polio survivors years after the initial infection and be very debilitating, have produced positive results.

Skipping one night of sleep causes healthy adults to see a spike in immune cells linked to chronic inflammation, a key feature of obesity, according to new research. It highlights the powerful link between sleep and immune health.

Human protection against bird flu may be easier than previously thought, thanks to new findings about the genetic makeup of the virus and one particular immune cell that all of us have. It also paves the way for fast-tracking the first H5N1 vaccine.

Scientists have uncovered a mechanism for reinvigorating the immune system to stop it from flagging when it’s fighting long-term conditions like chronic infections and cancer. It could make treatments more effective and improve clinical outcomes.

New research has found that a chemical abundant in fruits, vegetables and plant products can suppress the immune response seen in food allergies. It paves the way to developing a natural treatment for this globally increasing problem.

A new kind of cancer gene therapy can be remotely activated at a specific part of the body. The team developed a version of CRISPR that responds to ultrasound, and demonstrated how it can be used to clear cancer in mice.

Scarring of heart tissue can be slowed but not stopped, and can lead to heart failure. But a new study has shown that an existing immunotherapy could stop scar tissue formation after heart attacks.

When it comes to getting a cold or the flu, there is a commonly held belief that men take it harder than women, exaggerating their symptoms and basically acting like big ol' babies. But is this phenomenon of "man sick" a real thing? We investigate.

T cells are our first line of defense against cancer, but the battle tends to exhaust them. Now, scientists have found a way to give them extra “batteries” to keep them fighting longer, with promising early results in mice.
