How pollution and the microbiome interact with Tregs, the immune system regulators whose discovery was honored with the Nobel Prize

Researchers are gaining insights into how external factors like air pollutants, diet and medications, and even microbes in the gut interact with regulatory T cells, for better or for worse.

Coupes budgétaires dans la recherche médicale sous Trump : un impact majeur dans les États ruraux, notamment républicains

Les NIH, qui financent la recherche médicale aux États-Unis, ont annoncé des coupes budgétaires massives. Celles-ci vont affecter davantage les États ruraux qui, pour la plupart, ont voté Trump.

CDC greenlights two updated COVID‑19 vaccines, but how will they fare against the latest variants? 5 questions answered

Only time and data will tell whether the CDC-recommended reformulated shots can stand their ground against the ever-changing SARS-CoV-2 variants.

Pivotal points in the COVID‑19 pandemic – 5 essential reads

With the emergency phase of the COVID-19 pandemic in the rearview mirror, at least for now, we look back on a handful of stories that provided sharp insights at key moments in the pandemic.

Beneficios y riesgos de consumir gominolas y otros derivados del cannabis

Los investigadores trabajan para determinar cómo y qué productos del cannabis pueden ayudar a quienes padecen dolores crónicos o enfermedades graves. Pero a la ciencia le cuesta seguir el ritmo de un mercado en auge.

Cannabis‑derived products like delta‑8 THC and delta‑10 THC have flooded the US market – two immunologists explain the medicinal benefits and potential risks

Researchers are working to determine how and which cannabis products can help those suffering from chronic pain or serious illness. But science is having a hard time keeping up with the booming market.

People produce endocannabinoids – similar to compounds found in marijuana – that are critical to many bodily functions

A THC-like substance that occurs naturally in humans and other vertebrates helps maintain immunity, memory, nerve function and more – and research suggests a lack of it can harm health.
Insect bites or stings, like the one on this person’s hand, are a manifestation of inflammation. Suthep Wongkhad/EyeEm via Getty Images

What is inflammation? Two immunologists explain how the body responds to everything from stings to vaccination and why it sometimes goes wrong

Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.

How long does protective immunity against COVID‑19 last after infection or vaccination? Two immunologists explain

Because COVID-19 is a relatively new virus, researchers still aren’t sure exactly how long vaccines and prior infections provide protection.

Is the omicron variant Mother Nature’s way of vaccinating the masses and curbing the pandemic?

Some of the omicron variant’s unique properties – such as its ability to spread rapidly while causing milder COVID-19 infections – could usher in a new phase of the pandemic.

What does ‘survival of the fittest’ mean in the coronavirus pandemic? Look to the immune system

Who is most likely to survive an infection of the new coronavirus? Two immunologists explain that it is those who mount exactly the right immune response – not too weak, not too strong.
