Abortive infection of bat fibroblasts with SARS-CoV-2.

ABSTRACT: Bats are tolerant to highly pathogenic viruses such as Marburg, Ebola, and Nipah, suggesting the presence of a unique immune tolerance toward viral infection. Here, we compared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection of human and bat (Rhinolophus ferrumequinum) pluripotent cells and fibroblasts. Since bat cells do not express an angiotensin-converting enzyme 2 (ACE2) receptor that allows virus infection, we transduced the human ACE2 (hA) receptor into the cells and found that transduced cells can be infected with SARS-CoV-2. Compared to human embryonic stem cells-hA, infected bat induced Pluripotent Stem Cells (iPSCs)-hA produced about a 100-fold lower level of infectious virus and displayed lower toxicity. In contrast, bat embryonic fibroblast-hA prod
