The size and stiffness of red and white blood cells can change if people are infected with the coronavirus. Such a result was showed during the study of the blood samples of over 50 people. The results of the studies of the scientists of the Max Planck Institute for Medical Research and German Center Immunotherapy were published by Biophysical Journal.
The scientists analyzed data of 17 patients with different phases of coronavirus, 14 recovering patients, and 24 healthy people who entered the control group. The specialists studied over four million blood cells of the patients and compared them to the rates of healthy people.
“We found significant changes in lymphocyte stiffness, 12 monocyte size, neutrophil size and deformability, and heterogeneity of erythrocyte deformation and 13 size,” the publication states.
Some patients had their blood cells returned in the normal state a few months after recovering; while recovery of other patients have significantly delayed.
As we reported, Australian researchers have begun clinical trials of a new type of Covid-19 vaccine in the form of a nasal spray. The study was approved by an independent ethics committee. The nasal spray will be available in a year or two.
