Circulin B
Circulin B is a macrocyclic plant cyclopeptide. Circulin B functions as a plant defense peptide and exhibits antibacterial and anti-HIV activities. Circulin B has high binding affinity for the envelope protein of dengue virus, showing potential anti-dengue virus activity. Circulin B can be used in studies related to dengue virus infection, human immunodeficiency virus infection and microbial infection.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
