**Background of ICAM5 Recombinant Protein**
ICAM5 (Intercellular Adhesion Molecule 5), also known as Telencephalin, is a transmembrane glycoprotein belonging to the immunoglobulin (Ig) superfamily. Predominantly expressed in neurons of the telencephalon, it plays critical roles in synaptic plasticity, neuronal migration, and immune regulation within the central nervous system (CNS). Structurally, ICAM5 features nine extracellular Ig-like domains, a single transmembrane region, and a short cytoplasmic tail. Its unique domain organization distinguishes it from other ICAM family members, such as ICAM1 or ICAM2. which are broadly expressed in endothelial and immune cells.
Recombinant ICAM5 protein is engineered to study its biological functions and therapeutic potential. Produced via heterologous expression systems (e.g., mammalian CHO or HEK293 cells), the recombinant form typically includes the extracellular domain to enable ligand-binding studies without membrane-associated complications. This protein is pivotal in investigating interactions with ligands like leukocyte integrins (e.g., LFA-1) or pathogens (e.g., enterovirus 71), which exploit ICAM5 for host cell entry.
Research highlights ICAM5's dual role in neuroprotection and neuroinflammation. It regulates dendritic spine maturation and stabilizes synaptic connections under physiological conditions. Conversely, during neuroinflammatory diseases (e.g., Alzheimer's) or viral encephalitis, upregulated ICAM5 may exacerbate inflammation by facilitating leukocyte infiltration into the CNS.
Therapeutic applications of recombinant ICAM5 include developing inhibitors to block pathological integrin binding or viral entry, as well as biomarker discovery for neurological disorders. Its study also aids in understanding neuro-immune crosstalk, offering insights into targeted therapies for neurodegenerative and inflammatory diseases. Overall, ICAM5 recombinant protein serves as a vital tool bridging neuroscience, immunology, and drug development.
