For attachment, rabies virus binds to a

Correct answer: B. Integrin ICAM-1

  • A. Complement receptor
  • B. Integrin ICAM-1
  • C. Acetylcholine
  • D. Epidermal growth factor

Explanation

To clarify, the attachment of the rabies virus to host cells involves interactions between viral glycoproteins and specific receptors, and in the case of the rabies virus, one of the receptors used for attachment is the nicotinic acetylcholine receptor (nAChR). This receptor is normally associated with nerve signal transmission but is repurposed by the virus for attachment, facilitating its entry into host cells.

About Viruses

Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
