Abstract
VH3 and VH4 type immunoglobulins display superantigen-type binding affinity for the HIV gp120 envelope glycoprotein. VH3 and VH4 type antibody molecules, including IgG and IgM, are shown to suppress HIV infection in vivo and in vitro. Determining the level of such antibody molecules is correlated to the advancement of HIV disease state.
Claims3
A method of determining the HIV-1 disease state of a patient infected with HIV-1, comprising:
- obtaining a biological sample from said patient, said sample containing antibodies;
- determining the level of VH3-containing antibodies having gp120 binding activity in said sample;
- and
- comparing the determined level of said antibodies with a predetermined level of said antibodies in a biological sample from an asymptomatic HIV-1 infected patient, wherein a lower level in said biological sample from said patient relative to said predetermined level is indicative of a disease state more advanced than said asymptomatic HIV-1 infected patient.
