Characterization of alpha-defensins plasma levels in Macaca fascicularis and correlations with virological parameters during SHIV89.6Pcy11 experimental infection. | LitMetric

AI Article Synopsis

  • * Researchers measured alpha-defensins levels in healthy and SHIV-infected cynomolgus monkeys to understand their physiological response to infection.
  • * The study found that infected monkeys had higher alpha-defensins levels early on, with a notable difference in duration based on the infection route, indicating that mucosal infections may elicit a stronger and longer-lasting immune response than intravenous ones.

Article Abstract

Alpha-defensins have been shown to inhibit HIV-1 replication in vitro and may contribute to the overall control of viral replication in vivo. In the present work, we quantitatively measured the levels of alpha-defensins in the plasma of healthy and experimentally SHIV-infected Macaca fascicularis (cynomolgus monkeys), an animal model of AIDS pathogenesis and vaccine development. Characterization of physiological plasma alpha-defensins levels was performed in 12 healthy monkeys following longitudinal analysis using an alpha-defensins ELISA kit currently validated for macaque use. Subsequently, alpha-defensins levels were quantitatively measured in 23 cynomolgus monkeys during titration protocols following both the mucosal and systemic routes of infection with the pathogenic SHIV89.6P(cy11). A significant increase in plasma alpha-defensins levels was consistently observed at early time points in all infected animals, regardless of the infection route. Moreover, a positive correlation was observed between viral replication and levels of alpha-defensins during the acute phase of infection. Interestingly, in the animals infected through the mucosal route, alpha-defensins levels remained significantly higher at later time points, up to 19 weeks from the infection, while in cynomolgus infected intravenously, alpha-defensins levels returned to baseline levels by 4 weeks from infection, suggesting that the different route of infection may differently activate the innate immune response.
