Researchers have developed a vaccine that protects animals from Salmonella. These bacteria often escape the effects of vaccination by genetically modifying their protective coat. The researchers have succeeded in manipulating this process to lure the b…
How platelets help resolve lung inflammation
Scientists have found how platelets interacting with white blood cells contribute to the resolution of bacterial lung inflammation in mice. The results may help in the search for therapies to specifically regulate inflammation.
Scientists learn what fuels the ‘natural killers’ of the immune system
Scientists are understanding more about natural killer (NK) cells, which are your allies when it comes to fighting infections and cancer.
Researchers discover drug that blocks multiple SARS-CoV-2 variants in mice
A small molecule STING agonist was highly protective against the virus that causes COVID-19 and likely other coronaviruses, researchers have found.
Stem cell drugs surprise researchers: Could lead to better drugs in the future
Chemotherapy destroys stem cells, which then cannot develop into immune cells and become part of the body’s defenses. There are drugs that can remedy this, but previously we did not know exactly how these drugs worked. Now, a new study details their fu…
Versatile coronavirus antibody may be starting point for broader-acting vaccines
Scientists investigated how the immune system’s previous exposure to cold-causing coronaviruses impact immune response to COVID-19. In doing so, they discovered one cross-reactive coronavirus antibody that’s triggered during a COVID-19 infection.
Ultrasensitive blood test detects viral protein, confirms mRNA vaccine activates robust immune response
In series of samples collected from individuals vaccinated against COVID-19, an ultrasensitive test detected low concentrations of circulating antigen. Following robust production of antibodies, investigators found that the viral protein declined to un…
Salmonella use intestinal epithelial cells to colonize the gut
The immune system’s attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to scientists.
How ‘non-professional’ cells can trigger immune response
Researchers are finding new details on the complex dynamics involved in how organisms sense an infection from pathogens. The researchers found that worms can sense changes in their metabolism in order to unleash protective defenses, even if they don’t …
A COVID-fighter’s guide to T cells
A new paper brings together research findings from COVID-19 researchers around the world. The results are striking: human T cells can target more than 1,400 sites on the SARS-CoV-2 virus.
