Scientists have found a way to prove that biochemical signals sent from cell to cell play an important role in determining how those cells develop, findings that can help explain how stem cells differentiate and how cancer arises and proliferates, poss…
Immune memory less durable after severe COVID-19, study suggests
Patients recovering from severe COVID-19 may have a more dysfunctional B cell response than patients who had less-severe COVID-19, a new study suggests.
Disarming a blood-clotting protein prevents gum disease in mice
Blocking function of a blood-clotting protein, called fibrin, prevented bone loss from periodontal (gum) disease in mice, according to new research. The study suggests that suppressing abnormal fibrin activity could hold promise for preventing or treat…
Dietary fiber improves outcomes for melanoma patients on immunotherapy
Melanoma patients receiving therapy that makes it easier for their immune system to kill cancer cells respond to treatment better when their diet is rich in fiber, according to a large, international research collaboration.
CBD reduces glioblastoma’s size, supportive environment in experimental model
Inhaled CBD shrinks the size of the highly aggressive, lethal brain tumor glioblastoma in an animal model by reducing the essential support of its microenvironment, researchers report.
What makes an mRNA vaccine so effective against severe COVID-19?
A new study helps explain why mRNA vaccines have been so successful at preventing severe disease.
HIV infection: Better understanding the reservoir of virus in the body
Researchers have developed a method that allows resting human immune cells to be genetically analyzed in detail for the first time.
Dominant SARS-CoV-2 Alpha variant evolved to evade our innate immune system
The SARS-CoV-2 Alpha (B.1.1.7) variant mutated to evade our ‘innate immune system’, helping establish it as the world’s first ‘Variant of Concern’, a new study finds.
Researchers lay groundwork for potential dog-allergy vaccine
Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people–the first step in developing a vaccine against most causes of dog allergies.
T cells: No time to die
They are at the forefront in the fight against viruses, bacteria, and malignant cells: the T cells of our immune system. But the older we get, the fewer of them our body produces. Thus, how long we remain healthy also depends on how long the T cells su…
