mTORC1 hyperactivation in lymphangioleiomyomatosis leads to ACE2 upregulation in type II pneumocytes: implications for COVID-19

Eur Respir J. 2021 Feb 11;57(2):2002737. doi: 10.1183/13993003.02737-2020. Print 2021 Feb.

Abstract

Increased pneumocyte expression of the SARS-CoV-2 entry receptor ACE2 in lymphangioleiomyomatosis (LAM) is associated with upregulation of interferon pathways in natural killer cells as well as increased IL6 expression in LAM-associated fibroblasts https://bit.ly/34ChSsg
