Abstract
Hepatitis B virus (HBV) remains a major global public health challenge, with approximately 254 million individuals chronically infected worldwide. The interaction between HBV and the innate immune system has garnered significant attention within the scientific community, with numerous studies exploring this relationship over the past several decades. While some research suggests that HBV infection activates the host's innate immune response, other studies indicate that HBV suppresses innate immune signaling pathways. These conflicting findings underscore the complexity of the HBV-innate immunity interaction, which remains inadequately understood. This review aims to clarify this interplay by examining it from three perspectives: (a) studies showing HBV activation of innate immunity; (b) evidence suggesting HBV suppression of innate immunity; and (c) findings that support HBV's role as a stealth virus. By synthesizing these perspectives, we aim to deepen the understanding of virus-host interactions that are crucial to HBV persistence and immune evasion, with potential implications for developing new therapeutic strategies for chronic HBV infection.
