New approach with mRNA preparation reprograms T cells to attack heart fibroblasts

An experimental immunotherapy can temporarily reprogram patients' immune cells to attack a specific target via only a single injection of messenger RNA (mRNA), similar to the mRNA-based COVID-19 vaccines, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania.

SARS-CoV-2 appears to persist in organs throughout the body for months

The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leads to asymptomatic or mild symptoms in most cases. However, in a significant minority, it causes moderate or severe disease, with lung damage and sometimes multi-organ dysfunction, the origin of which is currently a matter of intense debate.

SARS-CoV-2 spreads through cell-to-cell transmission, study finds

The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found.
