The research suggests that these other tissues could potentially be targeted to help treat cancer. |
| Researchers identify a missing piece of the Lyme disease puzzle Posted: 13 May 2021 11:24 AM PDT Epidemic. Pandemic. These terms have become second nature to us, popping up in everyday conversation, and for good reason -- COVID-19 is the latest pandemic to pose a threat to humanity. But in recent months, far less attention has been paid to another widely spread problem that has been proliferating since the late 1970s: Lyme disease. |
| Posted: 13 May 2021 11:24 AM PDT Cooperation plays a crucial role in evolution.

| A delicate balance: Learning new ways that gut microbes educate the immune system Posted: 12 May 2021 01:40 PM PDT An immune system that mistakes our good gut bacteria for an enemy can cause a dangerous type of inflammation in the intestines called colitis. An immune system that looks the other way while gut microbes spill past their assigned borders is equally dangerous. Understanding how the immune system learns to make a brokered peace with its microbial residents, called the microbiota, is therefore an important area of research. |
| How the body builds a healthy relationship with 'good' gut bacteria Posted: 12 May 2021 01:40 PM PDT Research reveals insights into how the body maintains balance with 'good' gut bacteria that allows these microbes to flourish in the intestine but keeps them out of tissues and organs where they're not supposed to be. |
