Innate immunity constitutes the first line of immune defense. As a part of the body's innate immunity, the antimicrobial peptide LL-37 plays a crucial role in maintaining homeostasis, with two primary functions: direct antimicrobial activity and immunomodulation. Currently, research on LL-37 mainly focuses on its function, while its induced expression in vivo has rarely been studied. However, understanding the induced expression of LL-37 is essential for delving into the body's immune defense mechanisms. Therefore, this paper briefly reviewed the research progress on the synthesis and functions of LL-37, the factors inducing its secretion, and the regulatory pathways involved in its induced expression. The aim is to offer new insights into the regulatory pathways and immune defense functions of LL-37 in the human body.
