In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet in Sweden describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity, may contribute to future treatments for COVID-19, among other diseases.
The structure of the lungs exposes them to viruses and bacteria from both the air and the blood. Macrophages are immune cells that, among other things, protect the lungs from such attacks. But under certain conditions, lung macrophages can also contribute to severe lung diseases, such as chronic obstructive pulmonary disease (COPD) and COVID-19.

Different dimensions of psychopathic traits are associated with different brain abnormalities in youth, according to new research published in the As a neuropsychologist, the neuropsychology of psychopathy has been one of my research interests. More importantly, prior studies have largely focused on adult psychopathy and whether the same brain correlates apply to adolescents whose neuropsychological functioning is drastically changing over time warrants investigation, said study author Bess Yin-Hung Lam, a research assistant professor at The University of Hong Kong.
In the study, the psychopathic traits of 29 children living in Brooklyn, New York, were assessed when they were 7 to 10 years old. Four years later, the participants underwent magnetic resonance imaging (MRI) of the brain to assess gray matter volumes.
