MSH: Specific molecular components of the cell capable of recognizing and interacting with a virus, and which, after binding it, are capable of generating some signal that initiates the chain of events leading to the biological response.,CSP: viruses must first bind to their target cell's surface before infection can proceed; this is mediated by specific molecular receptors for certain viral antigens, many of which have other known functions; e.g., the MHC-II receptor CD4 is also an HIV receptor.,NCI: Cell surface molecules that are capable of interacting with virus particles, thereby mediating their entry into the cell or otherwise eliciting a cellular response.
