The adaptive immune system has two main ways of dealing with viral infection: the first targets viruses in its initial extracellular phase, the second targets infected host cells. '''B-lymphocytes''' are capable of producing Antibody to neutralize the spike proteins of the viral lipid envelope. This adaptive response depends on CD4 TH-1 cells monitoring blood-borne pathogens and returning to lymph organs for presentation to B cells, and can take considerably longer than the second response. '''Cytotoxic (CD8+) T cells''' target infected cells, which present any number of danger signals. Once alerted to the infection, CD8+ T-cells will recruit help and proceed to wipe out all infected cells in the area.
