HIV-positive women with low blood platelet counts face significantly higher risk of death compared to women with normal counts, according to a study presented today at the 46th Annual Meeting of the American Society of Hematology.
Findings come from the Women’s Interagency HIV Study, or WIHS, a prospective study of women living with HIV (as well as HIV-negative women for comparison) in six urban areas across the United States. In this portion of the study, researchers looked at 1,990 HIV-infected women and 553 HIV-negative women.
When entering the study, 15 percent of HIV-positive women and less than 2 percent of the HIV-negative women had low blood platelet counts, also called thrombocytopenia. Platelets are minute cells in the blood that help in the blood clotting process.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
