Inhibiting HIV Infection Using Integrin Antagonists


Infection with HIV depletes and impairs CD4 cells, a key component of the immune system. Effective therapies such as highly active antiretroviral therapy (HAART) have focused on preserving CD4 cells. However, long term HAART has significant toxicity associated with it. The current technology describes the use of integrin antagonists as an alternative to treating or preventing HIV infection and replication. Specifically, alpha4 integrin plays a role in directing lymphocytes to the primary site of HIV replication. Inhibition of the interaction of alpha4beta1 or alpha4beta7 with gp120 can therefore be important in the development of effective HIV treatments.
