Why zebrafish hearts heal so well: Early immune signals can improve repair even further
When the human heart is damaged by a heart attack, stiff scar tissue eventually forms around the affected areas. This weakens the heart's pumping ability and increases the risk of heart failure and arrhythmias. Zebrafish, ...

Blocking stress signals could limit harmful inflammation after heart attack
After a heart attack, the body rapidly floods the injured heart with neutrophils—white blood cells that help repair damage but can also make it worse when too many arrive too quickly. New research from the University of Oklahoma ...

Ticked off: How a bite can turn meat against you
Mammalian meat allergy (MMA) is one of the few known food allergies caused by an environmental trigger—a tick bite. In simple terms, MMA results in an allergic reaction to red meat, making it difficult or sometimes even impossible ...

Why this CAR T advance matters: Complete remissions without chemotherapy at doses as low as 250,000 cells/kg
Stem-cell memory T (TSCM) cells are a rare subset of immune cells with the ability to self-renew, persist long term, and mount potent anti-tumor responses. These properties make them an attractive candidate for next-generation ...

T cells secrete DNA to boost the immune system's cancer-fighting ability
Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell Medicine. The discovery ...

Restoring protein recycling helps exhausted T cells fight tumors again
T cells are crucial components of our immune system, serving as critical protectors against infection and disease. But there are limits to their defensive capabilities. T cells are not inexhaustible protectors. Often, when ...

Scientists recruit red blood cells to deliver genetic cargo with instructions to kill cancer
Scientists have developed a way to turn the body's own immune cells into cancer-fighting agents—without removing them from the body—by using red blood cells to deliver genetic instructions. Current CAR (chimeric antigen receptor) ...
How eating primes immune cells for future responses
Diets and healthy eating habits hold promise for preventing and treating diseases, but far less is known about acute effects on the immune system shortly after a meal.

Your nose may be the gateway to a stronger immune system
At the moment, an influenza vaccine called FluMist is the only licensed intranasal vaccine approved for use in humans. The vaccine is administered through a spray of fluid in the nose, rather than with an injection.

A natural molecule boosts CAR-T therapy and turns cold tumors hot
CAR-T cell therapy works well in blood cancers, but many patients still become resistant. A key reason is the presence of CAR-T regulatory T cells (CAR-Tregs), which weaken immune responses. Therefore, selectively targeting ...
