Lactylation, a novel form of post-translational modifications (PTMs) of protein, particularly within histone proteins, has recently gained attention for its role in regulating gene expression and cellular processes. In recent years, lactylation has been widely studied in cancer, immune diseases, neurological diseases, cardiovascular diseases, metabolic diseases, etc. Increasing evidence now suggests that lactylation also plays a significant role in the host's innate immune response to viruses. Lactylation influences fundamental cellular functions, including transcriptional regulation, signal transduction, cell proliferation and differentiation. It affects protein behavior by modulating their function, stability, subcellular localization and interactions. Studies have shown that many viral infections promote lactate production through enhanced glycolysis, a process that facilitates viral replication. Given that innate immunity serves as the host's first line of defense against pathogenic invasion, understanding how lactylation regulates antiviral responses offers promising avenues for the development of diagnostic tools and therapeutic strategies against viral diseases. In this review, we provide a comprehensive overview of recent research on the role of lactylation in viral-host interactions.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
