Researchers in France have discovered that patients suffering from severe COVID-19 show changes in a class of immune cells known as unconventional T cells. The study suggests that monitoring the activity of these cells in the blood of patients could predict the severity and course of the disease.

Cytokines play a crucial role in the immune response. If this immune response is too strong, also known as 'cytokine storm', it can cause harm to the patient. Following the measurement of several important cytokines in patients with COVID-19 and various other severe diseases, researchers show that COVID-19 is not characterized by a cytokine storm. This may have consequences for the treatment of these patients, the researchers write.

The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, 'heme' is produced, which in turn can influence the protein cocktail in the blood. Researchers have now discovered in complex detective work that the 'activated protein C' (APC) can be commandeered by heme. At the same time, APC can also reduce the toxic effect of heme.

Researchers have developed a unique method for precisely controlling the deposition of hydrogel, which is made of water-soluble polymers commonly used to support cells in experiments or for therapeutic purposes. The researchers noticed that their technique - which allows for the encapsulation of a single cell within a minute hydrogel droplet - can be used to coax bone marrow stem cells into specialized cells.

Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, researchers have designed a new mask intended to do just that -- and are providing the plans so individuals and manufacturers can make it.
