SARS-CoV-2 infects T lymphocytes through its spike protein-mediated membrane fusion

The clinical manifestations of COVID-19 include pneumonia, diarrhea, dyspnea, and multiple organ failure. Interestingly, lymphocytopenia, as a diagnostic indicator, is common in COVID-19 patients. Xiong et al. found upregulation of apoptosis, autophagy, and p53 pathways in PBMC of COVID-19 patients.3 Some studies reported that lymphocytopenia might be related to mortality, especially in patients with low levels of CD3+, CD4+, and CD8+ T lymphocytes.4,5 Lymphocytopenia was also found in the Middle East respiratory syndrome (MERS) cases.

Lymphocytopenia is the condition of having an abnormally low level of lymphocytes in the blood. Lymphocytes are a white blood cell with important functions in the immune system. It is also called lymphopenia. The opposite is lymphocytosis, which refers to an excessive level of lymphocytes. Lymphocytopenia may be present as part of a pancytopenia, when the total numbers of all types of blood cells are reduced.

Ein richtig unangenehmes Kerlchen, dieses Virus.
