**Background of LAIR1 Recombinant Protein**
LAIR1 (Leukocyte-Associated Immunoglobulin-like Receptor 1) is an inhibitory immune receptor belonging to the immunoglobulin superfamily. It is primarily expressed on leukocytes, including natural killer (NK) cells, T cells, B cells, and monocytes. LAIR1 plays a critical role in modulating immune responses by interacting with collagen and other extracellular matrix (ECM) components. Upon binding to its ligands, LAIR1 transmits inhibitory signals through immunoreceptor tyrosine-based inhibitory motifs (ITIMs) in its cytoplasmic domain, thereby dampening excessive immune activation and maintaining immune homeostasis.
The development of recombinant LAIR1 protein stems from its potential therapeutic and research applications. Recombinant LAIR1 is typically produced using expression systems (e.g., mammalian, insect, or bacterial cells) to ensure proper folding and post-translational modifications. This engineered protein often includes the extracellular domain of LAIR1. which retains its ligand-binding capacity.
Research on LAIR1 has gained momentum due to its dual role in immunity: it not only regulates autoimmune and inflammatory diseases but is also exploited by pathogens like *Plasmodium falciparum* (malaria parasite) to evade host immunity. For instance, malaria proteins mimic collagen to bind LAIR1. suppressing immune cell activity. Recombinant LAIR1 proteins are thus used to study these interactions, develop blocking agents, or engineer LAIR1-based biologics (e.g., fusion proteins with Fc regions) to enhance immune responses in cancer immunotherapy.
Additionally, LAIR1 recombinant proteins serve as valuable tools in structural studies, ligand screening, and diagnostic assays. Their therapeutic potential is being explored in autoimmune disorders, chronic infections, and cancer, where modulating LAIR1 signaling could restore immune balance or enhance pathogen clearance. Overall, LAIR1 recombinant protein represents a promising avenue for both understanding immune regulation and developing targeted therapies.
