UrduA mutation in a protein regulating natural killer (NK) cells’ function is at the root of immune deficiency in some people with a rare genetic condition characterized by cognitive and developmental delay, seizures, and other manifestations. The findings also have broader implications for immunity and cell therapies.

Central Park Zoo Releases Postmortem Testing Results for Flaco, the Eurasian Eagle Owl
The following statement was released today by Central Park Zoo:Postmortem testing has been completed for Flaco, the Eurasian eagle owl that was found down in the courtyard of a Manhattan building a little over a year after his enclosure at the Central Park Zoo was vandalized on February 2, 2023.
Mild Covid-19 infections make insomnia more likely, especially in people with anxiety or depression
A survey of people who had been diagnosed with Covid-19 but never hospitalized found that 76% developed insomnia — and anxious or depressed people were more vulnerable.
Cholesterol lures in coronavirus
New study shows that cholesterol aggregates can promote SARS-CoV-2 infection to help the virus invade cells
Physicians urged to consider fungal infections as possible cause for lung inflammation
UC Davis Health infectious diseases expert George Thompson warns of the rising threat and apparent spread of disease-causing fungi outside their traditional hot spots. Fungal lung infections are commonly misdiagnosed, leading to delays in treatment and increase in antimicrobial resistance in the community.
Flu causes cardiac complications by directly infecting the heart
Researchers have shown for the first time in mice that heart problems seen in some of the sickest flu patients are caused by direct influenza infection of cardiac cells.
Possible new antivirals against COVID-19, herpes
The immune system fights viruses with peptides. Now, scientists have treated animal models of herpes with synthetic peptide mimics known as peptoids. These molecules could one day cure or prevent many kinds of infections, including COVID-19. They will present their results at ACS Fall 2021.
Immune cell implicated in development of lung disease following viral infection
Scientists at Washington University School of Medicine in St. Louis have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
Am I Losing My Sense of Smell or Is It COVID-19
Do I have COVID-19 or is it something else? Bobby Tajudeen, MD, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center explains the differences between common smell loss and smell loss as a COVID-19 symptom and when to see a specialist.
ANTIVIRAL DEFENSE FROM THE GUT
Study demonstrates how a subset of common gut bacteria renders mice resistant to viral infections.
Microfluidics helps MTU engineers watch viral infection in real time
Watching a viral infection happen in real time is like a cross between a zombie horror film, paint drying, and a Bollywood epic on repeat. Over a 10-hour span, chemical engineers from Michigan Tech watched viral infections happen with precision inside a microfluidics device and can measure when the infection cycle gets interrupted by an antiviral compound.
Stopping lethal lung damage from the flu with a natural human protein
The raging lung inflammation that can contribute to death from the flu can be stopped in its tracks by a drug derived from a naturally occurring human protein, a new animal study suggests.
