UrduResearchers identified a key metabolite in cells that helps direct immune responses and explains at a single cell level why immune cells that most efficiently recognize pathogens, vaccines, or diseased cells grow and divide faster than other cells.

Engineered bacteria paint targets on tumors for cancer-killing T cells to see
Synthetic biologists at Columbia Engineering report today a new approach to attacking tumors. They have engineered tumor-colonizing bacteria (probiotics) to produce synthetic targets in tumors that direct CAR-T cells to destroy the newly highlighted cancer cells.
Asymptomatic infections may underlie recent rise in whooping cough
In a new study, scientists at La Jolla Institute for Immunology (LJI) compared the immune response of individuals who received older versus newer versions of the whooping cough vaccine. The unexpected findings may help explain the recent rise in whooping cough cases and point to potential targets for the next generation of vaccines.
“COVID rebound” is common, even in untreated patients
“COVID rebound,” in which evidence of the illness disappears and then returns days or weeks later, is surprisingly common—whether or not patients are given the antiviral Paxlovid.
Newly discovered surface structures may affect immune function
Using new microscopic methods in combination with machine learning-based image analysis, researchers from Freiburg have discovered new structures on the surface of living B cells that affect the distribution and possibly the function of their antigen receptors.
Quenchbody immunosensors pave the way to quick and sensitive COVID-19 diagnostics
The incredibly fast spread of COVID-19 throughout the world brought to light a very important fact: we need better methods to diagnose infectious diseases quickly and efficiently.
Early plasma antigen levels predict illness severity and clinical outcomes in hospitalized patients with COVID-19
A large cross-sectional study conducted in 114 centers in 10 countries confirmed that plasma viral antigen can be quantified in early samples obtained from patients hospitalized with COVID-19 and is highly associated with both baseline severity of illness and clinically important patient outcomes. The findings are published in Annals of Internal Medicine.
Researchers find new mechanism to turn on cancer-killing T cells
In a new study, researchers at the University of Chicago Medicine Comprehensive Cancer Center and the University of Amsterdam have brought insight into one crucial step in the anti-cancer immune response process: T cell priming.
This COVID-19 Detector Has Berkeley Lab Roots
A technology spun from carbon nanotube sensors discovered 20 years ago by Lawrence Berkeley National Laboratory (Berkeley Lab) scientists could one day help healthcare providers test patients for COVID-19, the disease caused by the coronavirus SARS-CoV-2.
