Collaborative Research and Licensing Opportunity: HIV targets CD62L on central memory T cells through viral envelope glycans for adhesion and induces selectin shedding for viral release
NIAID researchers have shown that inhibition of CD62L shedding dramatically reduced HIV-1 infection and viral release from both viremic and aviremic CD4+ T cells. Therefore, inhibitors for CD62L sheddase can function as an anti-HIV treatment that may be effective alone or in combination with existing therapeutics.
Despite the success of anti-retroviral therapy in controlling HIV in infected individuals, treatment is less effective at eliminating HIV viral reservoirs. The nature of HIV reservoirs and the factors controlling their size and release are a major research focus for achieving a cure for HIV/AIDS.
NIAID researchers have identified L-selectin/CD62L as a new target for treating HIV by inhibiting viral release from infected cells. They found that shedding of CD62L on T cells is required for the efficient release of HIV virus from infected cells. Further, they have shown that inhibition of CD62L shedding dramatically reduced HIV-1 infection and viral release from both viremic and aviremic CD4+ T cells. Therefore, inhibitors for CD62L sheddase can function as an anti-HIV treatment that may be effective alone or in combination with existing therapeutics.
