Broadly neutralizing antibodies are effective against multiple strains of a certain pathogen
and are of particular interest in the treatment of HIV
A broadly neutralizing antibody
neutralizes the effect of the antigen
to which it binds and thereby supports the immune defense. What is special about these broadly neutralizing antibodies is that they bind to conserved pathogen
surface structures. These targeted structures do not change much even if the pathogen is modified by mutation. Broadly neutralizing antibodies have been found against HIV
virus. They could in the future play a role in the development of a vaccine
against these viruses.
