Antibody and cellular immunity in severe vs. mild COVID-19

Now, a new study published in the journal Signal Transduction and Targeted Therapy in August 2020 shows that while humoral and T-cell immune responses are more robust in severe infection, the disease activates memory T cells as part of the adaptive immune system in COVID-19 patients irrespective of disease severity.

Targeting SARS-CoV-2 with off-the-shelf CAR-NK cells

The current COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread and cause disease and death in many countries even today. At present, there is no effective treatment. A recent study published on the preprint server bioRxiv in August 2020 reports the potential of a new class of drugs called CAR NK cells, which could be used off-the-shelf to treat this disease.
