Anti-Rhinovirus Capsid VP1 Antibody, clone HRV-18003

Rhinoviruses (RV) belong to the Picornavirus family and are known as a leading cause of respiratory infections. Over 160 different types of rhinoviruses have been identified and based on their genetic diversity and phylogenetic sequence analysis they are grouped as rhinovirus A, B, and C. Three different membrane glycoproteins are known to serve as receptors for these viruses. ICAM-1 is used by a majority of A group and all B group rhinoviruses, a small number of group A viruses use the low-density lipoprotein receptor (LDLR), and the group C of rhinoviruses use cadherin-related family member 3 receptor (CDKR3). Canyons on the surface of the virus are known to provide an attachment site for receptors on the surface of susceptible target cells. Viral infectivity is neutralized when host immunoglobulin G binds to the surface of the virus, thereby blocking interaction between the host cell receptor and the receptor binding site located at the base of the canyon. The RV is composed of single-stranded RNA within a capsid with icosahedral symmetry. The viral capsid of human RV is comprised of four viral proteins: VP1, VP2, VP3, and VP4. The remaining viral proteins are responsible for viral replication and subsequent assembly. Capsid protein VP1 forms an icosahedral capsid of pseudo-T=3 symmetry with capsid proteins VP2 and VP3. VP1 interacts with host cell receptor to provide virion attachment to target host cells. This attachment induces virion internalization. VP1 is the most exposed surface protein and plays a critical role in viral antigenicity and induction of neutralizing antibodies. Clone HRV-18003 binds to a conserve epitope within VP1 and displays cross reactivity with multiple types of rhinoviruses, including A1A, A1B, A15, and A49. It exhibits strong antibody dependent cellular phagocytosis (ADCP) against A1A and A16 viruses. (Ref.: Behzadi, MA., et al. (2020). Sci. Rep. 10(1):9750; Basnet, S., et al. (2019).
