Breakthrough stress sensor discovery reveals new mechanism of antimicrobial resistance

Researchers from the Antimicrobial Resistance (AMR) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, in collaboration with Singapore Centre for Environmental Life Sciences Engineering (SCELSE), Nanyang Technological University Singapore (NTU Singapore) and Massachusetts Institute of Technology (MIT), have discovered a new stress signaling system that enables bacteria cells to adapt and protect themselves against the immune system and certain antibiotics.

NIAID funds research to better understand Post-treatment Lyme Disease Syndrome

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has awarded five projects for research to better understand Post-treatment Lyme Disease Syndrome (PTLDS), which is a collection of symptoms, such as pain, fatigue, and difficulty thinking or "brain fog," which linger following standard treatment for Lyme disease.

Proteins CEACAM1 and TIM-3 may help protect liver transplants

A new study identifies how certain proteins in the immune system interact leading to organ rejection. The study, which involved experiments on mice and human patients, uncovered an important communication pathway between two molecules called CEACAM1 (CC1) and TIM-3, finding that the pathway plays a crucial role in controlling the body's immune response during liver transplantation.

Study provides new insights into how SARS-CoV-2 affects glucose metabolism

Research conducted at the University of São Paulo (USP) in Brazil shows that SARS-CoV-2, the virus that causes COVID-19, can infect liver cells (hepatocytes), stimulating glucose production and leading to a condition similar to diabetes (hyperglycemia) in hospitalized patients, even if their blood sugar level was normal before they were admitted to hospital.
