Hypothesis

Does Griffithsin have a safe and effective profile as a microbicide candidate against HIV?

Conclusion

Griffithsin has an outstanding safety profile with minimal toxicity and retains antiviral activity against HIV.

Supporting Evidence

  • GRFT binds to human epithelial and PBMC cells through oligosaccharide-dependent interactions.
  • GRFT treatment induces minimal changes in inflammatory cytokine secretion.
  • GRFT does not significantly upregulate markers of T-cell activation.

Takeaway

Griffithsin is a natural protein that can help prevent HIV without causing harm to human cells.

Methodology

The study involved binding assays, cell viability tests, and gene expression analysis using human cervico-vaginal cell lines and PBMC.

Potential Biases

Potential conflicts of interest due to funding sources and author affiliations.

Limitations

The study primarily focused on in vitro models, which may not fully represent in vivo conditions.

Participant Demographics

Freshly isolated PBMC from 3 different donors were used.
