Core Tip

Core Tip: The tremendous public health and economic impact of the coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a huge challenge for countries across the whole world. Increased evidences have revealed that SARS-CoV-2 also induced intestinal infection. Type III interferon (IFN), also called IFN-λ, plays an antiviral role in intestinal infection, and has focused, long-lasting, as well as non-inflammatory characteristics. In this review, we summarized the invasion and immune escape mechanisms of the SARS-CoV-2. Furthermore, we concerned about the gastrointestinal impact of the SARS-CoV-2 and the comprehensive role of IFN-λ, also called type III IFN, in anti-enteric SARS-CoV-2 infection.
