About Human LDL Receptor Class A Domain Containing 3 (LDLRAD3) Stable Cell Line

Low-Density Lipoprotein Receptor Class A Domain Containing 3 (LDLRAD3) is a member of the low-density lipoprotein receptor (LDLR) superfamily and is expressed in a variety of tissues, particularly within the central nervous system. Although the physiological functions of LDLRAD3 are not yet fully understood, emerging evidence suggests that the protein is involved in cell-cell interactions, receptor-mediated signaling, and neuronal biology. In recent years, LDLRAD3 has gained significant attention as a host factor involved in viral infection, particularly as an alternative receptor that can facilitate cellular entry of certain neurotropic viruses, including Venezuelan equine encephalitis virus (VEEV). As a result, LDLRAD3 has become an important target for studies of virus-host interactions, receptor biology, and antiviral therapeutic development.

The identification of LDLRAD3 as a viral entry factor has expanded interest in its biological functions and potential therapeutic applications. Studies have demonstrated that interactions between viral envelope proteins and LDLRAD3 can mediate viral attachment and entry into susceptible cells. These findings have established LDLRAD3 as a valuable target for investigating viral pathogenesis, host susceptibility factors, and the development of receptor-blocking antibodies and antiviral agents. Beyond infectious disease research, LDLRAD3 may also contribute to neuronal signaling pathways and cellular communication mechanisms that remain active areas of investigation.

Biological Significance of LDLRAD3

LDLRAD3 is an emerging receptor of significant interest in both receptor biology and infectious disease research. As a member of the LDL receptor family, LDLRAD3 contains characteristic ligand-binding domains that facilitate interactions with extracellular proteins and signaling molecules. Recent discoveries identifying LDLRAD3 as a host receptor for neurotropic alphaviruses have highlighted its importance in viral pathogenesis and host susceptibility. These findings have opened new opportunities for understanding viral entry mechanisms and developing receptor-targeted therapeutic strategies. In addition, the expression of LDLRAD3 within the nervous system suggests potential roles in neuronal function and cellular communication. Because of its growing importance as a viral receptor and potential signaling molecule, LDLRAD3 remains an active area of investigation in virology, neuroscience, and drug discovery research.
