WebJan 10, 2024 · 少部分人群，其肺泡巨噬细胞偏向M1型，则易被新冠病毒感染，且易发展为重症，但是正常人的肺泡巨噬细胞偏向M2型，通常抑制CTSL，从而能够较好抵御新冠病毒的入侵，表现为不发病或轻微感染。然而，Delta突变攻破了M2型肺泡巨噬细胞的防御机制。 WebCathepsin L (CTSL) is a lysosomal protease and is involved in a wide range of cellular functions with implications in disease. Badano and colleagues demonstrated that CTSL plays a role in the processing of antigenic peptides and negatively regulates B-cell production, maintaining homeostasis of B-cells ( Badano et al., 2013 ).
