LC3B: A microtubule-associated protein influences disease progression and prognosis

Abstract

Microtubule-associated protein 1 light chain 3B (MAP1LC3B, also known as LC3B) is a mammalian homolog of the autophagy-related protein 8 (ATG8) family. It plays a crucial role in cellular autophagy and is involved in several vital biological processes, including apoptosis and differentiation. Additionally, LC3B regulates immune responses. Due to its close association with malignant tumors and neurodegenerative diseases, and its potential as a prognostic indicator and therapeutic target, LC3B has become a significant research focus. This article aims to provide a comprehensive and systematic understanding of LC3B's role and mechanisms in autophagy, its impact on apoptosis and the underlying mechanisms, its regulation of cellular differentiation and transdifferentiation, its modulation of immune and inflammatory responses, the influence of upstream regulatory factors on LC3B's function, and its relevance to disease diagnosis, treatment, and prognosis. The goal is to establish a solid foundation for understanding LC3B's role in cellular processes and its regulatory mechanisms.
