A small study in 65 US women without HIV infection from the Study of Women’s Health Across the Nation (SWAN) found that fatty acid–binding protein 2, a marker of gut epithelial integrity, and soluble CD14 (sCD14), a marker of immune activation resulting from gut microbial translocation, increased in stored blood samples collected from 3 to 5 years after the FMP when compared to samples collected from 3 to 5 years prior to the FMP [32]. The gene discussed is FABP2; the disease is HIV infectious disease.
