Mechanism of ActionThymosin Alpha-1 modulates T-cell function, enhances dendritic cell maturation, and promotes Th1 immune responses. It increases IL-2, interferon-alpha, and interferon-gamma production while reducing inflammatory cytokines.Enfuvirtide is a 36-amino acid peptide that binds to HIV gp41, preventing the conformational change needed for virus-cell membrane fusion. This blocks HIV entry before the virus can infect the cell.
