Scientists uncover biological explanation for why upper respiratory infections are more common in colder temperatures
by Massachusetts Eye and Ear Infirmary Credit: CC0 Public Domain Researchers at Mass Eye and Ear and Northeastern University have discovered a previously unidentified immune response inside the nose that fights off viruses responsible for upper respiratory infections. Further testing has revealed this protective response becomes inhibited in colder temperatures, making an infection more likely...

Stressed mitochondria help cells survive respiratory infections
ECOLE POLYTECHNIQUE FÉDÉRALE DE LAUSANNE Many respiratory infections, such as influenza or COVID-19 add significant stress to cells and organs, which can lead to acute respiratory distress syndrome (ARDS), which itself can eventually cause death in aged or sensitive individuals. “Novel therapeutic strategies to address ARDS, instead of fighting the infectious agent, could try to...

New research on vitamin D and respiratory infections important for risk groups
Earlier studies have shown that supplementary vitamin D seems to provide a certain degree of protection against respiratory infections. A new study involving researchers from Karolinska Institutet has now made the most comprehensive synthesis to date of this connection. The study, which is published in the journal Lancet Diabetes & Endocrinology, confirms that vitamin D...
