Recombinant Human inlA Protein，His

InlA, also known as internalin A, is a surface protein produced by the pathogenic bacterium Listeria monocytogenes, which is known for its ability to invade human cells and establish infections. This protein plays a crucial role in the bacterium’s pathogenesis by facilitating its entry into epithelial cells through interaction with the host’s E-cadherin, a key component of cell-cell adhesion. The study of InlA is of significant interest due to its implications for understanding infection mechanisms and developing therapeutic interventions. Research has shown that the binding affinity between InlA and E-cadherin is essential for Listeria's virulence, making it a potential target for vaccine development and antibody-based therapies. Furthermore, examining the structural and functional aspects of InlA can provide insights into the broader category of microbial pathogenesis, particularly in how pathogens exploit host cell machinery. Recent studies have employed techniques such as X-ray crystallography and mutagenesis to elucidate the molecular interactions involved, revealing potential sites for drug design. Given the increasing incidence of listeriosis, particularly in immunocompromised individuals and pregnant women, understanding the role of InlA is critical not only for microbiology but also for public health initiatives aimed at preventing foodborne diseases. Thus, ongoing research continues to focus on InlA, aiming to uncover its complete functional landscape and harness this knowledge for innovative therapeutic strategies against L. monocytogenes infections.
